No substrate deformation and collapse, no strength reduction and cracks after welding.
无基材结构变形的影响，无变形及塌陷，焊接后强度减小和龟裂。

Through the analysis of material and construction, the dissimilar steel gear is successfully welded using stress reduction zone by heating and proper assemble and welding sequence.
ANAND viscoplastic constitutive equation was introduced into the FE model for calculation of the reduction of welding residual stresses during the post weld heat treatment.
