Abstract
Dissimilar metal joining of SUS304 stainless steel to A5052 aluminium alloy has been investigated by laser roll welding using a 2kW fiber laser. The effects of process parameters such as roll pressure and flux on the formation of intermetallic compound and the joint properties. In the case of using flux, most of the specimen were failured in the softened HAZ in tensile shear test. The higher the roll pressure is, the higher the tensile shear strength of specimen is. The joint efficiency was 85%.
