Effect of Adding Copper Foils on Seam Welding Joints of 304 Austenitic Stainless Steel

Abstract

The aim of this work is to study the effect of adding copper (C10200 AISI) foils on the welding joint of the austenitic stainless steel type (AISI 304).The austenitic stainless steel has low weldability by resistance welding where the concentrated current causing a high thermal expansion. Due to heat stored, non-complete fusion, burn throw, warp edge and distortion of weldments even when change machine settings. So to solve this problems a copper strips used as a filler metals between the stainless steel sheets, these problem disappears, because of that strip will be act as a heat sink and no burn through; but complete fusion, uniform weld
