Stainless　steel　sheet,　as　one　kind　of　energy-saving　materials　with　superior　performance,　has　been　widely　applied　to　national　production,　and　has　broad　application　prospects.　Based　on　the　importance　of　stainless　steel　sheet,　studying　the　welding　process　is　of　great　significance　to　promote　the　development　of　stainless　steel　sheet　industry.　In　this　paper,　the　effect　of　welding　process　on　weld　geometry　and　joint　properties　of　stainless　steel　sheets　are　reviewed.　Weld　geometry　of　laser　welding　joint　is　better　than　that　of　arc　welding　joint　for　stainless　steel　sheet　welding.　Good　weld　geometry　can　be　obtained　through　appropriate　shielding　gas　method　and　waveform　control.　High　energy　beam　welding　and　friction　stir　welding　can　optimize　the　joint　mechanical　properties　due　to　grain　refinement.　The　corrosion　sensitivity　of　joint　by　welding　process　of　low　heat　input　falls　off.　The　shielding　gas　flow　rate　and　external　magnetic　field　have　strong　positive　effect　on　corrosion　resistance.　©　2018,　The　Editorial　Board　of　Materials　China.　All　right　reserved.
