The four types of welded joint of 304 stainless steel sheet were obtained by TIG welding. They are full penetration butt joint

tee joint

one-side fillet joint and the lap joint. Their mechanical properties

microstructure

residual stress distribution

chloride ion sensitivity are tested and analysized. The results show that among the four types of welded joints

the full penetration butt joint is the best in terms of mechanical properties

residual stress distribution and corrosion resistance

while the one-side fillet joint is the worst in terms of mechanical properties

residual stress distribution and corrosion resistance.
