A Comparative Study of Abbreviated Heat Treatments for SAE 4130 Steel After Laser Welding

Abstract It was verified that SAE 4130 steel plates crack when laser beam welded at room temperature (RT). To overcome this problem, this work proposes a high temperature (HT) laser welding in order to reduce the residual stresses and create a bainitic structure instead of a martensitic one. A conve...
