Load-carrying capacity of overmatched welded joint of stainless steel for building structure

A finite element (FE) analysis of tensile test for a welded joint of austenitic stainless steel for a building structure SUS304A predicts necking in the weld metal as well as lower tensile strength than that of the base metal, even though the joints has the strength-overmatched weld metal. The FE an...

Description
Summary:	A finite element (FE) analysis of tensile test for a welded joint of austenitic stainless steel for a building structure SUS304A predicts necking in the weld metal as well as lower tensile strength than that of the base metal, even though the joints has the strength-overmatched weld metal. The FE analytical studies also suggest that such an anticipated deformation behavior comes from large difference in uniform elongation between the base metal and the weld metal. Experimental works for overmatched welded joints using SUS 304A and welding wire TS308MoJ supports the joint strength and the necking behavior demonstrated by the FE analysis. On the basis of parametric FE analyses, mechanical parameters that should be controlled to ensure the base metal necking and the tensile strength of a base metal in tensile test of the overmatched joint are proposed.
