Patch all-position welding method

The invention belongs to the technical field of repair plate welding, and discloses a repair plate all-position welding method which comprises the following steps: S1, dividing a welding seam of a repair plate into a plurality of sections according to the appearance of the repair plate; s2, a plurality of offsets and a plurality of welding gun postures are set according to the welding seams of different sections; and S3, according to the offset, welding gun postures are adopted, and the multiple sections of welding seams are welded correspondingly. According to the repair plate all-position welding method, the welding seam is divided into the multiple sections according to the appearance of the repair plate, the multiple offsets and the multiple welding gun postures are set, the welding angle of the welding gun is optimized, and therefore the offsets and the welding gun postures can better adapt to the position characteristics of all the sections of the welding seam; appearance defects such as offset welding
