Welded joints are the most active corrosion area of stainless steel. In order to improving the corrosion resistance, a novel electrochemical passivation technique is used to modify the surface of welded joint. The effect of treatment process is studied by potential nephogram and accelerated corrosion test. Furthermore, the influence of welding technology on anti-corrosion performance is investigated. Experiment result shows that the welded joints can get a better anticorrosive property by employing surfacing welding technology.
