Taking　the　2219　aluminum　alloy　as　the　research　object,　a　laser-driven　GMAW　metal　transfer　test　system　is　built.　High　speed　camera　system　is　used　to　capture　the　metal　transfer　process　and　the　effect　of　the　addition　of　laser　on　the　droplet　transfer　behavior　is　analyzed.　The　results　demonstrate　that　by　changing　the　process　parameters,　the　addition　of　a　laser　changes　the　force　state　of　the　droplet,　which　in　turn　changes　the　droplet　transfer　mode　and　the　flight　trajectory.　When　the　pulsed　laser　irradiates　the　neck　of　the　droplet,　the　resulting　recoil　force　can　effectively　promote　the　detachment　of　the　droplet　from　the　welding　wire　and　the　desirable　one　drop　per　pulse　transfer　is　obtained.　Better　weld　formation　is　obtained　because　the　transfer　process　is　more　stable.　The　process　can　not　only　improve　stability　of　the　metal　transfer,　effectively　improve　the　weld　formation,　but　also　appropriately　solve　the　problems　of　narrow　welding　process　transfer　range　of　the　aluminum　alloy　welding,　high　heat　input　to　the　base　metal　and　poor　stability　of　the　welding　process.　©　2019,　Editorial　Board　of　Transactions　of　the　China　Welding　Institution,　Magazine　Agency　Welding.　All　right　reserved.
