Talk:Shot welding

From Wikipedia, the free encyclopedia

"and high brief high currents a satisfactory spot" does not make sense. I presume the author meant "very" rather than the first "high".

Corrected to "and very brief high currents a satisfactory spot".

I have made this change, but have no background to confirm that the result is technically correct.

If the author is about I'd appreciate confirmation.

As a second point, I am familiar with the term spot welding, but not shot welding.

The techniques seem similar. Are these terms synonyms, or is there a subtle difference?

If so it would be sensible to point it out.

(Edit conflict as I typed my comments, so this can be read as a reply to the above) From the second sentence of the patent application noted in the references (italics are my own emphasis):

"... my invention relates to a method of spot welding certain stainless steels hereinafter pointed out, so as to preserve or substantially preserve at the welded portions of the resulting structure, the desirable characteristics of such steels. ..."

Further down, on page 3 of the text...

"I am aware of the fact that prior to my invention various kinds of stainless steels have been welded by the usual welding methods, such as butt welding, arc welding and spot welding, ... but such welding when applied to the character of stainless steels to which this invention is directed, is quite unreliable and unsatisfactory and results in destroying or materially impairing the desirable characteristics of such metal for many structural purposes."

This isn't spot welding, it's a specific type of spot welding called shot welding. Shot welding minimizes the damage done to the metal and substantially reduces the size of the weld itself. slambo 23:45, Mar 23, 2005 (UTC)
