The　high　energy　density　of　the　laser　beam　irradiated　the　droplet　to　make　it　be　subjected　to　local　strong　evaporation,　and　the　laser　recoil　force　was　used　to　drive　the　droplet　to　be　forced　short　circuit,　which　promoted　the　droplet　to　be　detached　from　the　wire.　Taking　the　mild　steel　as　the　research　object　and　using　the　high　speed　camera　equipment,　the　laser　enhanced　GMAW　short　circuiting　transfer　welding　test　system　was　built.　The　influence　of　laser　incident　position　and　arc　height　on　the　transfer　behavior　of　droplet　short　circuit　in　GMAW　short　circuiting　transfer　welding　process　were　studied.　The　results　show　that　the　laser　has　a　significant　effect　on　the　short　circuiting　transfer　behavior　of　the　droplet　during　the　welding　process.　The　force　state　of　the　droplet　can　be　changed,　which　can　control　the　size　of　the　droplet.　The　droplet　short　circuiting　time　decreases,　while　the　arcing　time　and　transfer　frequency　increase,　which　improves　the　stability　of　the　welding　process.　After　the　laser　is　applied,　the　metal　transfer　is　much　more　frequent　and　robust.　The　bead　formation　looks　fine　and　uniform.　©　2018,　Editorial　Board　of　Transactions　of　the　China　Welding　Institution,　Magazine　Agency　Welding.　All　right　reserved.
