Abstract: Full penetration welding process experiments had been carried out on 8 mm 304 stainless steel by hybrid laser-arc welding using high power disk laser and MIG arc. The effects on the weld formation and tensile property (tensile strength, elongation) of wire feeding speed, laser power, welding speed, distance between laser and arc were studied. The results show that it can decrease back hump and eliminate undercut leading weld formation improvement with increasing wire feeding speed. And it can improve tensile strength and elongation, but if the wire feeding speed is too big, the tensile strength would decrease. It can decrease back hump and eliminate undercut by enhancing laser power but the tensile strength and elongation would decrease. When the distance between laser and arc is 1 mm, it can obtain a good weld formation and the tensile strength and elongation are better. The tensile strength and elongation can be up to 695 MPa and 41.5%, which reach 97.89% and 76.85% of the base material, respectively.
