| description | The invention discloses an MIG repair welding method for an aluminum alloy butt joint. The MIG repair welding method for the aluminum alloy butt joint comprises the following steps of (1) removing the portion, 0-2mm away from a fusion line, of a weld joint potion of an original butt joint through a machining method, and enabling the original butt joint to be divided into two portions; (2) carrying out butt joint on the two workpieces on a horizontal platform, ensuring that mismatch between the workpieces does not exist, carrying out clamping on the two workpieces through clamping tools, and carrying out tack welding; (3) adjusting a welding gun device of an MIG welding machine to enable the included angle between the welding gun device of the MIG welding machine and the horizontal workpieces to range from 50 degrees to 70 degrees, wherein a welding nozzle of a welding gun of the MIG welding machine ejects protective gas while carrying out wire feeding, the welding speed of the welding gun is 0.35-0.56m/min, t |
