Direct joint of dissimilar materials between SUS304 stainless steel and plastics, PET (Polyethylene Terephthalate) or PC (Polycarbonate), was studied by using pulse YAG laser. Welding configuration was lap joint. Weldability and shear-tensile strength were investigated for the joints. It was possible to make a joint for both combination of materials, SUS304/PET and SUS304/PC. Weldable condition range was wider in case of SUS304/PET joint compared to that in case of SUS304/PC joint. The difference in the weldability may be due to difference in glass transition temperature of the plastics. Pores were observed in plastics near the interface of the joint for both combinations of the materials when the joint welded with higher heat input. Sear-tensile test was carried out for the joints. SUS304/PET joint shows higher strength compared to SUS304/PC joint. Higher strength was observed for the joint which includes pores near the interface in plastics. However, if large size and number of pores are existing near the interface in plastics, the pores play as a defect and causes degradation of the strength.
