In this research, the changes in the microstructures and mechanical properties in the welding zone and heat-affected zone (HAZ) of the welds between 304 stainless steel and SS400 carbon steel by Tungsten Inert Gas (TIG) with ER-309L welding rod were investigated. The formation of the micro-structure in areas, including the columnar-dendritic, was investigated by micro-cope equipment. The tensile strength results of weld-joint were performed on nine specimens using a Universal tensile and compression machine at Hung Yen University of Technology and Education show that the tensile of welds between SUS-304 stainless steel and SS400 carbon steel was achieved at 457MPa.
