| Abstract: | The welding technology of 304L/SA516Gr70 stainless steel composite plate is investigated.The transition region and clad metal are welded with ER309L welding wire by tungsten inert gas arc welding(GTAW),and the base metal is welded with E5015 electrode by shielded metal arc welding(SMAW).The mechanical properties of welded joints are tested.Results show that the tensile strengh of the joints reaches 573.4 MPa,and the joint failed in the position of base metal and it presents obvious characteristic of ductile... |
