Taking　2219　aluminum　alloy　as　the　welding　research　base　metal,　a　high　frequency　and　low　power　pulsed　laserMIG　hybrid　welding　system　was　established.　When　the　laser　pulse　frequency　ranges　from　500　Hz　to　1500　Hz　and　the　laser-wire　distance　ranges　from　1　to　2　mm,　the　effects　of　high-frequency　and　low-power　pulsed　laser　on　the　arc　shape,　metal　transfer　behavior,　and　weld　formation　in　the　hybrid　welding　process　were　compared　and　analyzed　by　using　high-speed　camera　system　and　electrical　signal　acquisition　system.　The　results　show　that　as　the　pulse　frequency　increases,　the　arc　is　gradually　compressed,　and　the　compression　reaches　the　maximum　when　the　frequency　is　1500　Hz.　In　the　test,　the　limit　distance　of　laser　attracted　arc　is　2　mm　and　the　limit　distance　of　laser　stabilized　arc　is　1.5　mm.　From　the　collected　electrical　signal,　it　can　be　seen　that　the　welding　current　is　reduced　by　5.8A　after　adding　laser　irradiation.　Since　the　welding　power　source　is　a　constant　voltage　source,　the　welding　voltage　is　almost　constant,　so　the　heat　input　of　the　welding　arc　to　the　base　metal　and　droplets　is　reduced　to　a　certain　extent.　When　the　laser　is　biased　laterally　along　the　welding　wire,　the　weld　morphology　also　shifts　from　the　center　to　the　laser　irradiation　point,　which　further　verifies　the　guiding　effect　of　the　laser　on　the　arc.　In　addition,　the　addition　of　the　laser　effectively　improves　the　stability　of　the　welding　process,　the　weld　seam　is　formed　uniformly,　and　the　oscillation　of　the　molten　pool　caused　by　the　laser　accelerates　the　discharge　of　gas　in　the　molten　metal,　which　effectively　reduces　the　pore　defects.
