In　order　to　avoid　splash　when　large　amount　of　heat　of　resistance　spot　welding　is　input　for　hot　stamping　high　strength　steel　and　meet　the　strict　requirements　for　assembly　under　laser　spot　welding,　a　new　welding　process　that　is　combination　of　resistance　spot　welding　and　laser　spot　welding　is　proposed.　The　welding　joints　were　obtained　through　the　combination　of　resistance　and　laser　spot　welding　process.　The　microstructures　of　various　regions　for　welding　joints　were　analyzed　with　scanning　electron　microscopy.　The　micro-hardness　distribution　of　welding　joints　was　tested　by　micro-hardness　testing.　The　mechanical　properties　of　welded　joints　under　different　welding　process　were　obtained　by　using　universal　tensile　machine,　and　the　fracture　mode　and　fracture　mechanism　were　analyzed.　The　results　show　that　the　welding　area　under　process　of　combination　of　resistance　and　laser　spot　welding　is　composed　of　resistance　welding　zone　and　laser　welding　zone.　The　microstructure　of　laser　nugget　zone　and　base　metal　are　lath　martensite.　The　heat　affected　zone　locates　outside　of　laser　ring　and　near　the　base　metal,　and　the　nugget　of　original　resistance　spot　welding　are　tempering　organization.　The　hardness　of　laser　nugget　zone　is　the　same　as　that　of　base　metal,　and　the　hardness　of　softening　zone　corresponding　to　the　tempering　zone　decreases　to　60%　of　that　of　base　metal.　The　softening　zone　outside　of　laser　ring　is　the　weak　region　for　tensile-shear　fracture.　The　obtained　welding　joints　by　this　combination　process　have　better　load　carrying　capacity　and　toughness　than　those　by　individual　resistance　spot　welding　or　laser　welding.
