[edit] ultrasonic welding

I know ultrasonic welding can be categorized as a type of cold-welding. Does anyone know if it is also a type of friction welding? Thanks. Marylee23 (talk) 21:12, 16 April 2008 (UTC)

[edit] Static and Kinetic Friction

The physics textbook I have here (Cutnell and Johnson) says that static and kinetic friction are thought to be caused by cold welding. I'm not comfortable enough of the fact to add the fact to the page without verification; any input? --ScottAlanHill 04:22, 8 June 2006 (UTC)

I was told this in an engineering class. Certainly it's not the only mechanism, but apparently it is one. —Ben FrantzDale 05:25, 8 June 2006 (UTC)

I've removed the edit claiming that cold welding was a myth. It looks like it was probably made by a reddit reader, based on the timing. I was told about cold welding in an engineering class, and the following links, when read carefully, support the position that cold welding does exist as a phenomenon -- that is, that it has been demonstrated in experiments -- but cannot, apparently, happen accidentally as is commonly beleived:

Also, http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=1136435, for someone who has access to the full text or a preprint, might be a good place to start looking for citations. --Evan


METAL EON here i was told by a navy engineer that cold welding is when you get two metals of any type and put on them a special type of metal that is like glue and smere it on the two metals together and the weld is finished that way it can be welded in the rain does any one know any more on the subject

Cold welding appears to me more general than galling. Also some test results have shown that you can have cold welding between dissimilar materials. Finally, environment has also an impact on cold welding susceptibility; ie material are more prone to cold welding under vacuum. —Preceding unsigned comment added by 20.137.18.50 (talk) 21:21, 27 March 2008 (UTC)

[edit] Galling

Because no one else has created a section for this, I will.

Galling, to me, seems sufficiently similar to Cold Welding to be included in this article, even if, as Metal Eon pointed out, it has slightly different requirements. Player 03 (talk) 02:01, 19 May 2008 (UTC)

I disagree since galling is a defect or undesired thing between metals. However, coldwelding is a fabrication process, and when executed provides a benefit (stress free microstructure, bonded subcomponents).Xonofon (talk) 02:08, 31 May 2008 (UTC)
