Abstract

Inmulti-pass welding, residual stress distribution and it's maximum value change with addition of
each pass. Finite element simulation can be used to estimate residual stresses. In this paper, transient
thermal fields and residual stresses due to multi-pass GTA welding of 304 stainless steel plates is investigated by experimental and numerical simulation. Two-dimensional un-coupled thermo-mechanical analysis has been performed using ANSYS 10. Residual stress measurement has been performed using hole-drilling method. The results of this study reveal that maximum residual stresses decrease with the increase of number of passes due to the increase of thickness, but it increase the width of tensile and compress zones.
