Laser induction-double-path MAG container fillet weld welding method and device

The invention relates to a method and a device for welding fillet welds of a laser induction-double-path MAG container, wherein a camera is used for acquiring a weld form image in real time and sending the weld form image to a controller, the controller is used for monitoring the change of the weld form, the welding speed and the welding power of each welding gun are adjusted according to the change of the weld form so as to adjust the state of molten pool metal, the thrust and the thrust direction of electric arcs on the molten pool metal are changed by adjusting the inclination angle of each welding gun, the molten pool form is changed, the matching effect of two weld passes is adjusted by adjusting the distance between two sliding blocks, through double-electric-arc cooperation, a first welding gun is adopted to construct a root concave surface, a second welding gun is adopted to fill a pit and cover the pit, and the electric arcs are attracted by laser, so that the electric arcs are deflected to the fillet welds to generate the thrust on the molten pool metal, the molten pool metal is not easy to collapse, good and stable external forms of the welds are formed, and the consistency of the welding quality is further ensured.
