In　order　to　analyze　the　effect　on　resistance　spot　welding　residual　stress　of　super　steel　under　different　process,　the　B1500HS　steel　sheet　which　is　after　the　quenching　process　of　the　fast　cooling　is　choosed　as　the　material　in　this　experiment.　The　resistance　spot　welding　component　is　conducted　by　German　spot　welding　robot　NIMAK.　The　X-ray　diffraction　method　is　used　to　measure　the　components　residual　stress　of　weld　nugget,　heat　affected　zone　and　parent　metal　area.　The　results　showing　that　the　residual　stress　is　distributing　symmetrically　around　the　welding　core　and　the　value　of　residual　stress　increases　first　then　decreases　from　welding　core　to　the　parent　metal.　Besides,　the　residual　stress　reaches　its　maximum　value　in　the　heat　affected　zone　and　characterized　by　tensile　stress,　then　it　reduced　to　be　pressure　stress　away　from　the　welding　core,　meanwhile　the　maximum　tensile　stress　significantly　powerful　than　the　maximum　pressure　stress.　The　electrode　diameter　can　increase　the　residual　stress　with　the　increase　of　welding　current　the　residual　stress　increasise　first　than　decrease.　The　forging　pressure　can　effectively　reduces　the　value　of　residual　stress.　©　2016,　Editorial　Board　of　Transactions　of　the　China　Welding　Institution,　Magazine　Agency　Welding.　All　right　reserved.
