How To Purge Stainless Steel Pipe

Properties Of Stainless - Purging Stainless Steel
In this video on the properties of stainless steel, I show 2 ways of backing up stainless steel to prevent sugaring and granulation. Neither yield a weld that is silver on the back..at least not every time. But both methods are quick and much easier than a total purge. One method is to use a block of copper or aluminum for backing. ... Get Content Here
