Effect of boundary conditions on residual stress and distortion in T-joint welds
TL;DR: In this article, the authors investigated the welding residual stress and distortion in T-joint welds under various mechanical boundary conditions, and the results showed that the transverse residual stress, vertical displacement, angular distortion and transverse shrinkage depend significantly on the boundary conditions and the influence on the longitudinal residual stress is not significant.

A new finite element model for welding heat sources
TL;DR: In this article, a double ellipsoidal geometry is proposed to model both shallow penetration arc welding processes and the deeper penetration laser and electron beam processes, which can be easily changed to handle non-axisymmetric cases such as strip electrodes or dissimilar metal joining.
