Abstract The weldability of Al mass fraction 4% 304, 2% 316L stainless steel hot-rolled sheet was investigated. By using manually TIG, microstructure of weld joint was analyzed by optical microscopy, the distribution elements of welding base metal was measured by electron microprobe (EMPA) , mechanical properties of welded joints was also tested. The investigations of microstructure and mechanical properties show that the aluminum-containing 304 and 316L alloy hot-rolled plates are selected ER308L, ER316L as welding materials, after TIG welded, the weld area has no cracks, gas porosities and other defects, the joint has good strength and ductility, the mechanical properties of the weld joint is similar with the base metal. Heat-affected zone and base metal organization is basically the same, the fusion is well between the weld area and base metal, the microstructure is good, adding aluminum 304 and 316L stainless steel with good weldability.
