RE: Toroid made easy

Howdy Ian,

	Could you elaborate?  Stainless steel TIG welds better (easier) than
any other material.  When you weld it, it melts.  After it cools it is
contiguous stainless steel with the original adjacent areas. You can easily
spin, or form a blank created by two equal pieces welded and ground smooth
with a seam down the middle and never know that the blank wasn't sheared
from a single sheet.  Nothing is ruined. A welded area on stainless steel
has discoloration (oxidation?) from the heat.  This is easily removed either
chemically or mechanically.  So what do you mean when you say the stainless
steel is "ruined" when it gets red hot?

Regards,

Al Erpel
