Paper Title:
Numerical Simulation of Residual Stresses in Single Pass Butt-Weld of Dissimilar Pipe Joint during the Fusion Welding Process
  Abstract

Dissimilar metal welded joints are widely used in engineering structures nowadays. Among the various types of material combinations, dissimilar welded joints of carbon steel and austenitic stainless steel are very common in shipbuilding, nuclear and chemical industries. In this study the finite element software MSC.Marc is employed to calculate the welding residual stresses in dissimilar butt-welded Q235 steel and 304 stainless steel pipes with different welding currents. The calculation results indicate that the welding residual stresses present asymmetric distribution, peaks of residual stresses on inner surface tend to be in 304 stainless side which can be significant higher than the yield stresses of parent metals. Changing in welding current does not have a significant effect on the peak of stress in weld center line.
