In　the　laser　pulse-assisted　metal　transfer　process,　the　recoil　force　generated　at　the　laser　incident　point　replaced　the　electromagnetic　force.　A　stable　one　droplet　per　pulse　(ODPP)　short-circuiting　or　spray　transfer　process　obtained　at　a　relatively　low　current.　The　morphology　of　the　solid-liquid　interface　changes　after　the　laser　incident,　and　there　is　a　relatively　complicated　force-heat　interaction　phenomenon/process.　Firstly,　the　evaporation　mass　of　the　droplet　surface　after　laser　irradiation　was　measured,　and　the　evaporation　power　consumption　of　the　laser　to　the　droplet　was　calculated.　According　to　the　melting　increment　of　the　welding　wire,　the　melting　power　consumption　of　the　pulse　laser　on　the　welding　wire　was　calculated.　The　dynamic　change　process　of　metal　plume　was　observed　by　a　high-speed　camera.　According　to　the　experimental　calculation,　the　initial　velocity　of　droplet　falling　off　the　welding　wire　was　measured,　and　the　horizontal　and　vertical　impact　force　of　the　pulsed　laser　on　the　droplet　was　obtained.　The　total　evaporation　recoil　force　was　7.81　x　10-2　N.　Secondly,　the　temperature　changes　of　characteristic　points　around　the　molten　pool　under　different　laser　process　parameters　were　measured.　With　the　increase　of　laser　pulse　frequency/laser　power,　although　the　heat　input　of　the　base　metal　gradually　increased,　the　measured　temperature　rise　of　the　characteristic　points　was　less　than　the　temperature　of　the　laser-arc　hybrid　process.　The　deposition　rate　of　dual-pulse　laser-assisted　GMA　welding　at　75　Hz　is　about　1.4　times　that　of　traditional　MIG　welding.
