Paper Abstract

Laser welding of SUS 316 stainless steel was conducted in a 2 KW CO,laser and a good butt weld was formed. Weld appearance, microstructure, composition and corrosion resistance performances were investigated by a HITACHI X-650 scanning electron microscope, a PHILIPS EDAX PV9100 energy dispersive spectrum meter and a corrosion-electrochemistry microcomputer on line measuring system. It is found that columnar and equiaxed grains are well bound in the weld. Intergranular corrosion resistance property of the weld is improved with high contents of nickel, chromium and molybdeum in the boundaries. The weld presents the same excellent corrosion resistance property as the base metal in 10% NaOH solution, and provides better corrosion resistance performance in 1 N H2SO4solution.
