Conventional　pulsed　laser-enhanced　gas　metal　arc　welding　(GMAW)　employs　a　single　fiber　laser　focused　and　aimed　on　the　droplet　neck　position　to　produce　a　laser　recoil　force　and　thus　ensure　the　droplet　detachment　despite　the　amperage　of　the　welding　current.　One　drop　per　laser　pulse　metal　transfer　is　obtained,　and　the　droplet　deflects　away　from　the　wire　axis　along　the　laser　incident　direction.　This　implies　that　the　droplet　trajectory　may　also　be　controlled　if　the　direction　of　the　laser　recoil　force　can　be　adjusted.　Such　a　controllability　is　expected　to　bring　an　entirely　new　capability　to　the　GMAW　process:　active　control　on　the　weld　beam　geometry.　To　this　end,　double-sided,　laser-enhanced　GMAW　was　proposed　and　experimentally　verified　in　this　paper.　The　two　lasers　were　symmetrically　positioned,　and　both　aimed　at　the　droplet　neck.　The　laser　pulse　peak　power,　duration,　and　pulse　phase　of　the　two　lasers　can　all　be　programmed　to　regulate　the　laser　recoil　forces.　The　metal　transfer　under　twin　laser　irradiations　(same　laser　pulses　and　phases)　was　first　verified.　Then　the　effectiveness　on　controlling　the　droplet　trajectory　of　three　proposed　control　strategies　-　peak　power　matching,　peak　width　matching,　and　phase　matching　of　the　two　lasers　-　were　evaluated.　The　results　showed　laser　peak　power　matching　is　optimal　for　obtaining　desired　droplet　trajectory.　Since　the　laser　can　be　easily　controlled　in　real　time,　the　transfer　frequency,　droplet　size,　and　trajectory　can　all　be　adjusted　in　real　time,　and　the　metal　transfer　evolves　into　programmable　transfer.
