I reworked the history section, but this article is still seriously lacking pictures. If someone would add some it would be much appreciated. Marylee23 ( talk) 14:30, 9 April 2008 (UTC)
The reference article for "the first ultrasonic welded car" is unverifiable. A car is never mentioned in that article. I was never able to find a reference to a vehicle made entirely out of ultrasonic plastic welding. — Preceding unsigned comment added by Mazerinth ( talk • contribs) 18:37, 30 November 2013 (UTC) I was hoping someone would be able to help me flush out the history section and maybe add some pictures.

I would like to make some changes to this article possibly including changing the history section or adding a section. Please let me know what you think. -- Marylee23 05:49, 19 February 2008
"Although there is heating, it is not enough to melt the base materials. Vibrations are introduced along the joint being welded.....Ultrasonic welding appeared in the mid 60's and is rapidly developing. In its infancy, only hard plastics could be welded because their properties were the only fitting—they were acoustically conductive and had a low melting point."
sooo....-- Deglr6328 09:15, 30 August 2006 (UTC)
The difference between ultrasonic plastics welding and metals welding is one of 90 degrees. In a plastics welder the parts are vibrated in a compressive manner. In most cases, the plastics welder is a pneumatic press although it could be hydraulic or mechanical. The parts are squeezed together with a certain amount of static force. Then an ultrasonic vibration in line with the compressive force is introduced. Crudely put, it's like a very low-amplitude, very fast, jack hammer. The plastic at the mating surfaces melts and is squashed together.
A metals welder vibrates the material in a shear or scrubbing manner. The joint most always will be some form of a lap joint. The press squeezes the two overlapping pieces together just as in the plastics welder. However, instead of "hammering" in-line with the force, the vibration is introduced at right angles to the clamping force. So as the materials are being squeezed together (say, vertically), they are also being ultrasonically scrubbed at the mating surfaces (horizontally). The metal never melts. It just gets plastic like putty. The mating surfaces rapidly diffuse together,all in less than a second, generally.
The various manufacturers of metals welders predominantly derive their metals welders from their plastics welder designs. One manufacturer does it uniquely differently but it's somewhat more complicated. Common uses for ultrasonic metals welders are wire splicing, foil splicing, welding electrical contacts to internal components of things like relays, capacitors, and circuit breakers, and some uses for sealing refrigeration tubing in the manufacturing of refrigerators and freezers.

"Ultrasonic acoustic vibrations" in the first line is redundant. Should be "ultrasonic vibrations" with a parenthetical link to Acoustics if desired.
I think, the main point should not be "industrial technique" (this is nearly everything) but "type of friction welding" as it is seen by FW and USW specialists.-- UtzOnBikeEN ( talk) 19:50, 11 August 2008 (UTC)

From my own personal experience as a victim of directed energy technology, is that they are using ultrasound energy, as I have used lead, iron and aluminum for shielding but with no effect, but fuzzy materials tend to diminish the energy. In addition, the energy seems to be focused on the surface of the target, that is to say the fuzzy shielding inches away from the target surface do not provide protection. Aaron Alexis and Richard Weston Jr each claimed to be victims of directed energy, but the news reports discredit those claims as they also were reported to hear voices. I point out three flaws 1)that sleep deprivation from these devices can cause outward symptoms of mental illness, 2) sound communication can be modulated by this technology, 3) there is no rule that prohibits these devices to be covertly used on the mentally ill. My guess is that pulsed microwaves or pulsed lasers are being used to generate ultrasound vibrations in distant targets.
Another point is that even though the crowd control devices have been in field testing since at least 1998, they have not been marketed in public view to police departments despite clearly crowd control problems. I say this in an effort to make the public aware of this covert activity, please do not delete it. — Preceding unsigned comment added by 50.104.194.10 ( talk) 06:24, 29 May 2015 (UTC)
There are some problems with the sources. The "Plastics Technology" and "The Welding Institute" links are dead. Some of the sources are magazine articles or from industry sources.
Also, I think the References section should not have Notes and Bibliography subsections. Some notes are not included in the bibliography and vice versa.-- Missstarsineyes ( talk) 03:53, 22 January 2018 (UTC)
