Pulsed　laser　enhanced　metal　transfer　of　gas　metal　arc　welding　(GMAW)　is　a　recent　modification　of　conventional　GMAW　that　applies　a　relatively　low-power　pulsed　laser　to　the　droplet.　Previously　current-independent　metal　transfer　of　carbon　steel,　in　free-flight　or　short-circuiting　mode,　was　achieved　by　utilizing　single-side　pulsed　laser　irradiation　on　the　droplet.　However,　there　are　few　studies　on　laser　enhanced　aluminum　alloy　metal　transfer　of　GMAW　due　to　the　high　reflectivity　of　aluminum　alloy.　In　addition,　the　low　melting　point　of　aluminum　alloy　makes　it　possible　to　cut　off　the　welding　wire　(irradiate　on　the　wire)　directly　by　pulsed　laser　with　high　energy　density,　instead　of　irradiating　on　the　solid-liquid　interface　of　the　droplet.　Hence,　the　laser-enhanced　aluminum　alloy　metal　transfer　process　is　studied　in　this　paper.　The　results　demonstrate　that　when　the　pulsed　laser　irradiated　the　solid-liquid　interface　of　the　droplet,　the　laser　was　found　to　lead　to　a　significant　increase　in　the　stability　of　welding　process　as　an　additional　detaching　force　and　change　the　transfer　mode　and　flight　path　of　the　droplet.　Both　the　short-circuiting　(SC)　transfer　and　the　spray　transfer　processes　were　promoted　by　changing　the　stress　state　of　the　droplet,　and　the　transfer　frequency　was　effectively　increased.　Moreover,　when　the　pulsed　laser　irradiated　the　welding　wire,　the　welding　wire　was　cut　off　and　the　arc　climbed　to　the　laser　incident　point.　The　cut　wire-droplet　(W-D)　changed　into　a　molten　droplet　by　the　heating　of　the　arc　and　entered　into　the　molten　pool.　A　new　spray　transfer　balance　formed　at　the　incident　point　and　the　restriction　that　the　laser　must　impinge　on　the　solid-liquid　(S-L)　interface　of　the　droplet　was　released.
