Finite-element minimization of the welding distortion of dissimilar joints of carbon steel and stainless steel

Abstract

In the present study, on the basis of a verified model, the effects of geometrical and operational variables on the welding distortion of dissimilar joints were investigated. Then, considering the welding current, the fixing time and the sequence of the welding operation, the magnitude of the welding deformation was minimized. The results showed that in the studied dissimilar joint between carbon steel and stainless steel, the minimum distortion occurred when the welding current was about 95 A, the fixing time was 120 s and the symmetric layout was used.
