The　behavior　of　short-circuiting　transfer　controlled　by　single　pulsed　laser　irradiation　is　studied.　The　high　energy　density　of　the　instantaneous　laser　pulse　acts　on　the　droplet.　The　resulting　local　strong　laser　recoil　force　stretches　the　droplet　toward　the　weld　pool　with　slight　radical　deflection　due　to　the　use　of　single　side　laser.　Consequently,　the　droplet　is　forced　to　short-circuit　with　the　weld　pool.　And　the　liquid　bridge　of　molten　metal　is　thus　formed.　Since　the　laser　irradiation　still　exists,　the　liquid　bridge　is　continuously　forced　necked　till　the　droplet　is　detached　from　the　wire　tip.　Based　on　the　observation　of　single　pulse　laser　driven　droplet　transfer　in　the　absence　of　arc,　the　short-circuiting　transfer　of　pulsed-laser　enhanced　small-current　GMAW　is　further　analyzed.　The　results　show　that　application　of　laser　pulse　with　a　certain　peak　power　and　pulse　frequency　has　obvious　effect　on　the　short-circuiting　droplet　transfer　behavior.　The　drop　size　can　be　controlled　by　adjusting　the　laser　pulse　parameters.　One　droplet　per　laser　pulse　short-circuiting　transfer　is　obtained　and　the　welding　process　stability　is　improved.　©　2018,　Editorial　Board　of　Transactions　of　the　China　Welding　Institution,　Magazine　Agency　Welding.　All　right　reserved.
