Numerical Investigations on Residual Stress in Laser Penetration Welding Process of Ultrafine-Grained Steel
Weld solidification crack prevention in the laser penetration welding process is essential for the strength of the welded component.The Everything Else formation of solidification cracks can ultimately be attributed to welding residual stresses, and preventive measures should be taken during welding.In this study, the effects of residual stresses o
