Welding equipment and welding method for anti-corrosion shell

The invention relates to the technical field of automatic welding, in particular to welding equipment for an anti-corrosion shell and a welding method thereof.The welding equipment comprises a machine body, symmetrically-arranged supports are evenly and fixedly connected to the outer wall of the machine body, suction cups are arranged at the other ends of the supports, and an XY-axis transmission device is fixedly connected to the inner wall of the machine body; the machine body is adsorbed to the crack, needing to be welded, of the anti-corrosion shell through the suction cup, the XY-axis transmission device drives the welding gun to conduct welding along the crack, the welded weld joint is automatically polished after welding, the excess weld metal and residues generated after welding of the weld joint of the anti-corrosion shell are cleaned through polishing, and therefore the concentrated stress of the weld joint is reduced, and the welding quality of the anti-corrosion shell is improved. And meanwhile, t
