PRELIMINARILY TREATING METHOD FOR DIFFUSION WELDING OF STAINLESS STEEL* ALUMINUM OR ALUMINUM ALLOY

摘要

PURPOSE:To enable the effective diffusion welding, by electrolyzing in the electrolytic solution using the welding material consisting of stainless steel or Al(alloy) as the anode, removing the oxide and nitride coating on the surface and then immediately plating a specified metal respectively using the welding material as the cathode.
