There is no section inside of wikipedia explicitly covering plug welds (or at least that link to it). Someone with information on the subject needs to create an article. Plug welds are the welds that have a base metal and a hole in the second metal piece to be joined, the hole is filled with the filler metal when on top of the base metal and the two pieces are joined. Similar to spot welds but not at all the same —Preceding unsigned comment added by 12.155.97.57 ( talk) 18:56, 9 July 2008 (UTC)

Regarding the images that I'm looking for: I guess you could call them line drawings of the individual processes, such as SMA welding and GTA welding, as well as the torches used in GTA welding or Plasma arc welding. I'm not sure how easy that would be to do on CAD... I've done some work in CAD before as well and I tend to think that simply using drawing software would be easier. But my skills in that are limited – so far I've just done the uncomplicated joint design and HAZ images. Now, however, I'm not sure that those will be necessary for the welding article, since we a few more images of the processes used were just added. For the articles the individual processes, however, line drawings would be really useful.
Thanks for that picture of a fillet joint – we just have to figure out where to insert it. I'm planning to do some serious updating to the joinery article so that it includes welding joints as well, and that image could certainly be added there. On this article however, since such a small area is devoted to joint design, I'm not sure if it will fit. If you disagree, we can work something out, but I feel like this is just a general summary of joint design and that the images in the geometry section are of the type we need. Let me know what you think. -- Spangineer ∞ 19:12, May 15, 2005 (UTC)
Congratulations on achieving Featured Article status.... Very cool. I'm doing some of my regular money making business today, however I should be able to do a roughed-out cut away GMAW that we can use to haggle over the details with. I should be able to work on that this evening, and if not, tomorrow then. I'll post the rough draft JPEG in the commons, and link here for comments. Talk to you soon....

Oxy-acetylene is not a gas, but a kind of torch that uses a mixture of gases. You could say "oxy-acetylene torch" or process or even " oxy-acetylene welding", but strictly speaking, not " oxy-acetylene gas". I am also surprised that robotic welding is called "robot welding," which might better mean the welding of parts to make robots, but I guess if that is the term used in the trade, it has to be used.
Also in the first diagram you are intending to put in place you have two different spellings in the same picture: "electrafied" and "electrified" - the latter being the correct one. Better fix it before displaying it.
Also, simultaneously, at the same time you write "also flows simultaneously" which is redundant - "simultaneously" is enough already.
Also you have used the word "effect" instead of "affect" in "adversely effect the work piece" and I *think* you mean "workpiece" not "work piece". "Workpiece" is in Merriam Webster~ and I really think it is more appropriate. Pdn

Let's discuss how the images and text can be made more effective.
Why is there an image of the Delhi iron pillar on this page? It doesn't appear to be referred to in the text at all, and has little to do with welding.
Second line in the History section: " Welding was used in practical in welding until about 1900, when a suitable blowtorch was developed." Any ideas what the author may have intended? I would think fire, but I'm not about to guess the intent. Hard to believe that got approved to the main page.

I notice that this type of welding, which is increasing in popularity (particularly in the aviation industry, where it was recently FAA approved as a fabrication process for the new Eclipse personal jet), gets somewhat short-shrift in the welding section. At the least, a link to http://en.wikipedia.org/wiki/Friction_Stir_Welding would seem appropriate, yes? —Preceding unsigned comment added by Jkh ( talk • contribs)
I might have misunderstood, but the third paragraph of the summary starts 'Until the end of the 19th century' and then goes on to mention siginificant developments in the 1800s. Shouldn't it be 18th century ? (I guess I should 'be bold' and change it) Lee Elms 08:55, 9 February 2006 (UTC)
It seems the above MIG torch image would improve the article. This isn't a specialized item of narrow interest. Close up views of a MIG torch are seen every week on popular Discovery Channel TV shows, including American Chopper. Lots of viewers probably wonder what it is and how it works. Putting the above image in the article would make easy to recognize by sight, even if they didn't know the name. Joema 14:30, 20 May 2006 (UTC)
Recommend adding short section on weld symbols or a reference to a new page/longer article on weld symbols. See http://www.welding.com/weld_symbols_welding_symbols.shtml for detailed info from welding.com. —Preceding unsigned comment added by 161.209.206.1 ( talk • contribs)
Reinserted the discussion of sculptors who weld -- using American sculptor Jim Gary as an example of one who developed the skill of welding before becoming a sculptor and was renowned for his extremely effective use of the skill. Please let me know what type of references would suffice if the ones provided are not what the editor who deleted the edit had in mind... ---- kb -
The Submerged arc welding article mentions some welding positions (1F, 1G, 2F, 2G) but doesn't say what they are. The main Welding article should define all of the welding positions. I did some searching and found a page on the JEFF BONNER R&D, INC. website which describes his capabilities; it includes the following text (not to be used as-is, but for informational content only):
Sheet groove weld position: 1G; flat, 2G; horizontal, 3G; vertical, and 4G; overhead position:
Sheet fillet weld position: 1F; flat, 2F; horizontal, 3F; vertical , and 4F; overhead
Tube groove weld position: 1G; horizontal rolled, 2G; vertical, 5G; horizontal fixed, and 6G; inclined position.
Tube fillet weld position: 1F; flat, 2F; horizontal, 4F; overhead, and 5F; multiple position.
I'm guessing the "G" suffix means "groove", and the "F" suffix means "fillet", but we really need confirmation all of this. —The preceding unsigned comment was added by Dtgriscom ( talk • contribs) 02:44, 3 February 2007 (UTC).
I believe these terms are standard; when I find these terms on the Web, the context almost always implies that the viewer should know what they mean. In addition, the implied meanings seem very consistent. I also think they should be included in the Welding article rather than any subsidiary article. (If we won't include the definitions in the main page, then I agree that the SAW page should use the position names.)
Here's another page that gets a bit more explicit on the terms (although there's still ambiguity: what's the difference between the "Flat" and the "Horizontal" position?): Sim Welder Features Dan Griscom 11:29, 3 February 2007 (UTC)
Bingo. I finally found a relevant page at Fundamentals of Professional Welding: Welding Positions. This states that the various welding positions are defined by the American Welding Society, and then defines each one. Dan Griscom 11:55, 3 February 2007 (UTC)

I agree. I was reading the article for the first time and found that someone had vandalized the names of the sections. Took only a second to change, but changes like that should not be allowed. --the authentic david christians ( talk) 14:45, 20 April 2009 (UTC)
I was very surprised to see that this is a Featured Article (although I'm not suggesting it does not deserve the accolade). I came here while checking links I was adding to boiler, in a section mentioning how earlier boilers used rivetted construction and later ones were welded. In the UK, at least, the earliest bridges, fabricated frameworks, boilers, fireboxes, and ships were all constructed using rivets, and welding only came on the scene much later. Therefore, how come this article doesn't describe the relationship between the two joining technologies? nor even provide a link to rivet? This would appear to be a significant omission from the topic coverage (for example, when did welding establish itself as the preferred technology, compared to rivetting?).

I just tried to correct a link and promptly not only had my revision reverted but the link itself deleted. The link was to "The Welding Institute" at www.twi.co.uk. This name was inaccurate as twi.co.uk is the homepage of TWI Ltd, a research organisation focused around welding, wheras 'The Welding Institute" refers to a professional body for welders. Therefore the name of the link needed to be changed. If it's felt that using TWI's full name 'TWI - World Centre for Materials Joining Technology' is unnecessary then fair enough, but the link should not be called 'The Welding Institute'.
I don't know why the link was deleted althogether: it's been on this page for some time and quite rightly. Twi.co.uk hosts a major online database of information on welding (possibly the worlds biggest) much of which can be accessed by creating a free account and is a major source of welding information on the web. It's also one of the most influential welding organisations in the world, and is several times larger than EWI which has a similar role and continues to be linked from this page.
This longstanding link was removed completely with no explanation. Unless someone's got a good reason for taking it off (while leaving the link to EWI on) I'll replace it as (the correct) TWI Ltd. —Preceding unsigned comment added by 194.128.9.129 ( talk) 12:25, 20 August 2009 (UTC)
Just seen "Wizard191 (talk | contribs) (44,945 bytes) (Reverted 1 edit by 194.128.9.129; Rmv per WP:ELNO point 6. using TW"
This is not correct. ELNO point 6 discourages "Links to sites that require payment or registration to view the relevant content", but much of the relevant content on TWI requires neither payment nor registration. See, for example, the comprehensive seventy plus webpages on 'Job knowledge for welders' ( http://www.twi.co.uk/content/prof_jobknow.html). These are undeniably valuable, covering everything from cutting and gouging, health and safety, standards, weldability of materials, avoidance of defects, equipment, processes, etc. and are accessible without any payment or registration whatsoever. ELNO doesn't forbid linking to sites with valuable, accessible and "relevant" content just because they have other content which requires registration so long as there is relevant content which justifies its inclusion. I'll restore the link, please explain here if there is any reason why it should be removed. —Preceding unsigned comment added by 194.128.9.129 ( talk) 13:40, 20 August 2009 (UTC)
If you're concerned about the front page then why don't we link directly to the technical information page rather than removing the link althogether: http://www.twi.co.uk/content/tec_index.html ? It seems rather extreme to completely remove a longstanding link to a site with a huge amount of free technical information on welding just because of a slightly bombastic front page! Accusations of 'laywering' are rather unfair: if a site contains over 70 pages of high quality, free content without requiring registration does it really matter if they ask for payment or registration to access other content? —Preceding unsigned comment added by 194.128.9.129 ( talk) 13:59, 20 August 2009 (UTC)
Dear MrOllie, I've worked there in the past, which is why I noticed the name of the link on this page was seriously out of date. I spent part of my time there working on website content which is why I was frustrated at the kneejerk assumption that because it's a commercial site there's no valuable free content on there: I know that the welder knowledge pages in particular are some of the best free content available on the web. Thank you for your note regarding the 'three revert limit' by the way. I'm afraid I hadn't edited wikipedia before and I apologise if I broke any rules. If it's decided that the link doesn't add any value to the page then please delete it, I only wanted to draw attention to the technical information available on the site (which is presumably the reason why the link was put on and then remained on a formerly featured page for so long before I drew attention to it by correcting the name). I just ask that you look at the link I provided earlier in the talk before you make a decision. The exchanges surrounding this page have convinced me that I don't have the detailed knowledge of wikipedia's rules and guidelines (or the commitment needed to gain such knowledge!) necessary to make a useful contribution to the site so I won't post any more edits and I'll leave you and the other experienced contributers to decide what should be done with this page. I apologise if I've wasted your time. —Preceding unsigned comment added by 80.168.241.1 ( talk) 16:42, 20 August 2009 (UTC)

The development of nanotechnology has had a noticeable impact on welding techniques. Perhaps there should be an entry on the topic of nano-welding which would present these new methods. [1] [2] [3] ADM ( talk) 18:04, 21 February 2010 (UTC)
One thing I am confused about in the Butt Welding section are the advantages/disadvantages of using closed welds instead of open welds. I would think that using open welds would be more advantageous because it allows the molten metal to flow in between the two pieces and provides a larger surface area to bind to, yielding a stronger weld. My thinking may be wrong, but it would be interesting to have an explination on when both types of welds are used. Also, it mentions that open welds have a small gap in between the two pieces, but how small of a gap is it? It may be helpful to try to include some numbers. —Preceding unsigned comment added by Abethke ( talk • contribs) 19:33, 7 April 2010 (UTC)
Appearantly, there also exist "welding/tool belt quilts". I saw it being used by Kiki Pettit at Junkyard Mega Wars. Although I don't want to make a point about the quilts themselves, what struck me is the fabric they were made of; I don't think that this material is already discussed here (ie btw neither is the NASCAR carbon fibre mentioned in Smash Labs: "Forest fire"). 91.182.169.138 ( talk) 12:05, 17 September 2010 (UTC)

This article could use some referencing improvements. There are places that would be helped by having additions of cites, to satisfy verifiability for the reader. If not objected to by significant contributors to the article, I would be willing to identify some of these deficient locations in the article with {{ fact}} tags.

In "history" chapter, it reads: "During the 1920s, major advances were made in welding technology, including [...] During the following decade, further advances allowed for the welding of reactive metals like aluminum and magnesium. "

(see the talk page for the full story) For a while we deliberated on an article (Signature image processing) which appeared to be about a general technology for real-time weld monitoring but was actually about a particular supplier's product and method. Has a large amount of interesting content. We also noticed that there was no article on weld monitoring / testing, nor much on it in the welding article. We elected to morph the article into one on Weld monitoring, testing and analysis in general, making the previous article a (mere) section in the new article. Also knowing that the other sections would be stubs for now, but that such would hopefully be an impetus for developing them. We recently did it and the article is not in that state at Weld monitoring, testing and analysis. Of course, all are welcome to edit, including fleshing out those stub sections.

It seems to me that this article should have a section about the welding of non-metals. I see that we briefly mention plastic welding in passing, but do not describe it in any detail. There is also chemical welding of plastics, and welding of glass, which is a common glass blower's practice. (Any others?) If no one has any objections, I may add something in the near future.

This section seems pretty well-written, as an article on Metallurgy in general, but doesn't really have much to say about how welding processes affect the metallurgy or about how different metallurgical states affect the welding process, which is what I was expecting here.

The entry contains the word "aluminum" (6 times) as well as the word "aluminium" (once, and once in the notes).

It appears to me that electric shock, or electrocution avoidance should be added, in summary and links, to the Welding Safety Issues discussion. If it is already there somehow, I did not find it; and think it is worthy of emphasis. Aside from personal safety, It might be a factor for novices choosing electric vs gas welding, or in comparing shock safety of the many welding types? I am not expert re this, but Lincoln Electric and other sources have extensive information that could be inserted and referenced.

Under the heading "PROCESSES: Processes", the final sentence of the second paragraph reads "Furthermore, the process is generally limited to welding ferrous materials, though special electrodes have made possible the welding of cast iron, nickel, aluminum, copper, and other metals." Of course, cast iron is a ferrous material, so I think the sentence should be rephrased to acknowledge that fact, or perhaps cast iron should be dealt with in a separate sentence. Any suggestions?

"In some linguistic and physics circles, it is debated if welding can ever refer to joining non-metals. Many dictionaries refer to welding as a process specific to metal unless identified otherwise. aka Cambridge https://dictionary.cambridge.org/us/dictionary/english/weld."
I reverted this edit twice now, so per policy I am bringing it to the talk page for discussion. The problems with this addition are many. First are the use of weasel words, such as the all-knowing "they" or in this case "in some circles." What circles specifically say this. We need a source that specifically names these circles, which the dictionary does not.
The dictionary doesn't even say this. It simply defines the process as joining two pieces of metal together. Other dictionaries, such as https://www.collinsdictionary.com/us/dictionary/english/welding specifically say "plastics and metals", while yet others put the word metal in parentheses, indicating the word is most often used for metals, but not solely. And no dictionary would ever say that language could never change, because they all change constantly. The Oxford English department has written extensively on this, plus nearly every dictionary describes it in detail right in the front of the book.
The main problem is that a dictionary is only good for defining words, not for defining things. An encyclopedia is about defining things, so, unless the article is about a word, a dictionary is a useless source for defining the thing. Many other sources such as the book Fabrication and Welding Engineering by Roger Timings, Handbook of Laser Welding Technologies by S Katayama, or Welding of Plastics by TWI Core Research are much more reliable sources about the subject.

This article has (and it's children have) a bunch of great images. What we really need, and what I can't find anywhere on the 'net is a photo taken through welding glass of what the welder sees.

The photo with the comment "arc welding" has the title of Smaw. The photo is not of stick, it's a photo of either flux core (fcaw-s) or dual shield (fcaw-g). Judging from the amount of fumes coming off his arc, I would say it's dual shield, but I can't say that for sure as I can't see his welder. Not a huge thing, I just thought people shouldn't be confused by the article. 138 ( talk) 20:04, 13 March 2008 (UTC)

Regarding the images that I'm looking for: I guess you could call them line drawings of the individual processes, such as SMA welding and GTA welding, as well as the torches used in GTA welding or Plasma arc welding. I'm not sure how easy that would be to do on CAD... I've done some work in CAD before as well and I tend to think that simply using drawing software would be easier. But my skills in that are limited – so far I've just done the uncomplicated joint design and HAZ images. Now, however, I'm not sure that those will be necessary for the welding article, since we a few more images of the processes used were just added. For the articles the individual processes, however, line drawings would be really useful.
Thanks for that picture of a fillet joint – we just have to figure out where to insert it. I'm planning to do some serious updating to the joinery article so that it includes welding joints as well, and that image could certainly be added there. On this article however, since such a small area is devoted to joint design, I'm not sure if it will fit. If you disagree, we can work something out, but I feel like this is just a general summary of joint design and that the images in the geometry section are of the type we need. Let me know what you think. -- Spangineer ∞ 19:12, May 15, 2005 (UTC)

Oxy-acetylene is not a gas, but a kind of torch that uses a mixture of gases. You could say "oxy-acetylene torch" or process or even " oxy-acetylene welding", but strictly speaking, not " oxy-acetylene gas". I am also surprised that robotic welding is called "robot welding," which might better mean the welding of parts to make robots, but I guess if that is the term used in the trade, it has to be used.
Also in the first diagram you are intending to put in place you have two different spellings in the same picture: "electrafied" and "electrified" - the latter being the correct one. Better fix it before displaying it.
Also, simultaneously, at the same time you write "also flows simultaneously" which is redundant - "simultaneously" is enough already.
Also you have used the word "effect" instead of "affect" in "adversely effect the work piece" and I *think* you mean "workpiece" not "work piece". "Workpiece" is in Merriam Webster~ and I really think it is more appropriate. Pdn

Let's discuss how the images and text can be made more effective.
Why is there an image of the Delhi iron pillar on this page? It doesn't appear to be referred to in the text at all, and has little to do with welding.
Second line in the History section: " Welding was used in practical in welding until about 1900, when a suitable blowtorch was developed." Any ideas what the author may have intended? I would think fire, but I'm not about to guess the intent. Hard to believe that got approved to the main page.

I notice that this type of welding, which is increasing in popularity (particularly in the aviation industry, where it was recently FAA approved as a fabrication process for the new Eclipse personal jet), gets somewhat short-shrift in the welding section. At the least, a link to http://en.wikipedia.org/wiki/Friction_Stir_Welding would seem appropriate, yes? —Preceding unsigned comment added by Jkh ( talk • contribs)
I might have misunderstood, but the third paragraph of the summary starts 'Until the end of the 19th century' and then goes on to mention siginificant developments in the 1800s. Shouldn't it be 18th century ? (I guess I should 'be bold' and change it) Lee Elms 08:55, 9 February 2006 (UTC)
It seems the above MIG torch image would improve the article. This isn't a specialized item of narrow interest. Close up views of a MIG torch are seen every week on popular Discovery Channel TV shows, including American Chopper. Lots of viewers probably wonder what it is and how it works. Putting the above image in the article would make easy to recognize by sight, even if they didn't know the name. Joema 14:30, 20 May 2006 (UTC)

Please let me know what type of references would suffice if the ones provided are not what the editor who deleted the edit had in mind... ---- kb -
The Submerged arc welding article mentions some welding positions (1F, 1G, 2F, 2G) but doesn't say what they are. The main Welding article should define all of the welding positions. I did some searching and found a page on the JEFF BONNER R&D, INC. website which describes his capabilities; it includes the following text (not to be used as-is, but for informational content only):
Sheet groove weld position: 1G; flat, 2G; horizontal, 3G; vertical, and 4G; overhead position:
Sheet fillet weld position: 1F; flat, 2F; horizontal, 3F; vertical , and 4F; overhead
Tube groove weld position: 1G; horizontal rolled, 2G; vertical, 5G; horizontal fixed, and 6G; inclined position.
Tube fillet weld position: 1F; flat, 2F; horizontal, 4F; overhead, and 5F; multiple position.
I'm guessing the "G" suffix means "groove", and the "F" suffix means "fillet", but we really need confirmation all of this. —The preceding unsigned comment was added by Dtgriscom ( talk • contribs) 02:44, 3 February 2007 (UTC).
I believe these terms are standard; when I find these terms on the Web, the context almost always implies that the viewer should know what they mean. In addition, the implied meanings seem very consistent. I also think they should be included in the Welding article rather than any subsidiary article. (If we won't include the definitions in the main page, then I agree that the SAW page should use the position names.)
Here's another page that gets a bit more explicit on the terms (although there's still ambiguity: what's the difference between the "Flat" and the "Horizontal" position?): Sim Welder Features Dan Griscom 11:29, 3 February 2007 (UTC)
Bingo. I finally found a relevant page at Fundamentals of Professional Welding: Welding Positions. This states that the various welding positions are defined by the American Welding Society, and then defines each one. Dan Griscom 11:55, 3 February 2007 (UTC)

I was very surprised to see that this is a Featured Article (although I'm not suggesting it does not deserve the accolade). I came here while checking links I was adding to boiler, in a section mentioning how earlier boilers used rivetted construction and later ones were welded. In the UK, at least, the earliest bridges, fabricated frameworks, boilers, fireboxes, and ships were all constructed using rivets, and welding only came on the scene much later. Therefore, how come this article doesn't describe the relationship between the two joining technologies? nor even provide a link to rivet? This would appear to be a significant omission from the topic coverage (for example, when did welding establish itself as the preferred technology, compared to rivetting?).

I just tried to correct a link and promptly not only had my revision reverted but the link itself deleted. The link was to "The Welding Institute" at www.twi.co.uk. This name was inaccurate as twi.co.uk is the homepage of TWI Ltd, a research organisation focused around welding, wheras 'The Welding Institute" refers to a professional body for welders. Therefore the name of the link needed to be changed. If it's felt that using TWI's full name 'TWI - World Centre for Materials Joining Technology' is unnecessary then fair enough, but the link should not be called 'The Welding Institute'.
I don't know why the link was deleted althogether: it's been on this page for some time and quite rightly. Twi.co.uk hosts a major online database of information on welding (possibly the worlds biggest) much of which can be accessed by creating a free account and is a major source of welding information on the web. It's also one of the most influential welding organisations in the world, and is several times larger than EWI which has a similar role and continues to be linked from this page.
This longstanding link was removed completely with no explanation. Unless someone's got a good reason for taking it off (while leaving the link to EWI on) I'll replace it as (the correct) TWI Ltd. —Preceding unsigned comment added by 194.128.9.129 ( talk) 12:25, 20 August 2009 (UTC)

This is not correct. ELNO point 6 discourages "Links to sites that require payment or registration to view the relevant content", but much of the relevant content on TWI requires neither payment nor registration. See, for example, the comprehensive seventy plus webpages on 'Job knowledge for welders' ( http://www.twi.co.uk/content/prof_jobknow.html). These are undeniably valuable, covering everything from cutting and gouging, health and safety, standards, weldability of materials, avoidance of defects, equipment, processes, etc. and are accessible without any payment or registration whatsoever. ELNO doesn't forbid linking to sites with valuable, accessible and "relevant" content just because they have other content which requires registration so long as there is relevant content which justifies its inclusion. I'll restore the link, please explain here if there is any reason why it should be removed. —Preceding unsigned comment added by 194.128.9.129 ( talk) 13:40, 20 August 2009 (UTC)
If you're concerned about the front page then why don't we link directly to the technical information page rather than removing the link althogether: http://www.twi.co.uk/content/tec_index.html ? It seems rather extreme to completely remove a longstanding link to a site with a huge amount of free technical information on welding just because of a slightly bombastic front page! Accusations of 'laywering' are rather unfair: if a site contains over 70 pages of high quality, free content without requiring registration does it really matter if they ask for payment or registration to access other content? —Preceding unsigned comment added by 194.128.9.129 ( talk) 13:59, 20 August 2009 (UTC)
Dear MrOllie, I've worked there in the past, which is why I noticed the name of the link on this page was seriously out of date. I spent part of my time there working on website content which is why I was frustrated at the kneejerk assumption that because it's a commercial site there's no valuable free content on there: I know that the welder knowledge pages in particular are some of the best free content available on the web. Thank you for your note regarding the 'three revert limit' by the way. I'm afraid I hadn't edited wikipedia before and I apologise if I broke any rules. If it's decided that the link doesn't add any value to the page then please delete it, I only wanted to draw attention to the technical information available on the site (which is presumably the reason why the link was put on and then remained on a formerly featured page for so long before I drew attention to it by correcting the name). I just ask that you look at the link I provided earlier in the talk before you make a decision. The exchanges surrounding this page have convinced me that I don't have the detailed knowledge of wikipedia's rules and guidelines (or the commitment needed to gain such knowledge!) necessary to make a useful contribution to the site so I won't post any more edits and I'll leave you and the other experienced contributers to decide what should be done with this page.

One thing I am confused about in the Butt Welding section are the advantages/disadvantages of using closed welds instead of open welds. I would think that using open welds would be more advantageous because it allows the molten metal to flow in between the two pieces and provides a larger surface area to bind to, yielding a stronger weld. My thinking may be wrong, but it would be interesting to have an explination on when both types of welds are used. Also, it mentions that open welds have a small gap in between the two pieces, but how small of a gap is it? It may be helpful to try to include some numbers. —Preceding unsigned comment added by Abethke ( talk • contribs) 19:33, 7 April 2010 (UTC)

(see the talk page for the full story) For a while we deliberated on an article (Signature image processing) which appeared to be about a general technology for real-time weld monitoring but was actually about a particular supplier's product and method. Has a large amount of interesting content. We also noticed that there was no article on weld monitoring / testing, nor much on it in the welding article. We elected to morph the article into one on Weld monitoring, testing and analysis in general, making the previous article a (mere) section in the new article. Also knowing that the other sections would be stubs for now, but that such would hopefully be an impetus for developing them. We recently did it and the article is not in that state at Weld monitoring, testing and analysis. Of course, all are welcome to edit, including fleshing out those stub sections.

It appears to me that electric shock, or electrocution avoidance should be added, in summary and links, to the Welding Safety Issues discussion. If it is already there somehow, I did not find it; and think it is worthy of emphasis. Aside from personal safety, It might be a factor for novices choosing electric vs gas welding, or in comparing shock safety of the many welding types?

Under the heading "PROCESSES: Processes", the final sentence of the second paragraph reads "Furthermore, the process is generally limited to welding ferrous materials, though special electrodes have made possible the welding of cast iron, nickel, aluminum, copper, and other metals." Of course, cast iron is a ferrous material, so I think the sentence should be rephrased to acknowledge that fact, or perhaps cast iron should be dealt with in a separate sentence. Any suggestions?

"In some linguistic and physics circles, it is debated if welding can ever refer to joining non-metals. Many dictionaries refer to welding as a process specific to metal unless identified otherwise. aka Cambridge https://dictionary.cambridge.org/us/dictionary/english/weld."
I reverted this edit twice now, so per policy I am bringing it to the talk page for discussion. The problems with this addition are many. First are the use of weasel words, such as the all-knowing "they" or in this case "in some circles." What circles specifically say this. We need a source that specifically names these circles, which the dictionary does not.
The dictionary doesn't even say this. It simply defines the process as joining two pieces of metal together. Other dictionaries, such as https://www.collinsdictionary.com/us/dictionary/english/welding specifically say "plastics and metals", while yet others put the word metal in parentheses, indicating the word is most often used for metals, but not solely. And no dictionary would ever say that language could never change, because they all change constantly. The Oxford English department has written extensively on this, plus nearly every dictionary describes it in detail right in the front of the book.
The main problem is that a dictionary is only good for defining words, not for defining things. An encyclopedia is about defining things, so, unless the article is about a word, a dictionary is a useless source for defining the thing. Many other sources such as the book Fabrication and Welding Engineering by Roger Timings, Handbook of Laser Welding Technologies by S Katayama, or Welding of Plastics by TWI Core Research are much more reliable sources about the subject.

The photo with the comment "arc welding" has the title of Smaw. The photo is not of stick, it's a photo of either flux core (fcaw-s) or dual shield (fcaw-g). Judging from the amount of fumes coming off his arc, I would say it's dual shield, but I can't say that for sure as I can't see his welder.
