Due to the obvious change of the weld structure and the original base metal structure after laser processing, under the action of instantaneous high energy density laser beam, the weld structure is coarse and the strength, plasticity and toughness are reduced. Compared with the base metal, the microstructure of the alloy after laser welding was studied by experiment.
