Thin-wall component recombining and restoring method based on pulse welding and laser augmented material restoring

The invention discloses a thin-wall component recombining and restoring method based on pulse welding and laser augmented material restoring. The method is characterized in that firstly, the distribution and trend of cracks and other penetrating damage are determined through a coloring check method; secondly, grinding treatment is conducted through a hard alloy rotary file, and a penetrating groove in a relatively regular shape is formed; thirdly, optimal grinding of a pulse welding groove is conducted; fourthly, cleaning of the penetrating groove and a groove body of the penetrating groove is conducted; fifthly, pulse welding bridging restoring of the penetrating groove is conducted; sixthly, a bridging welding restored body is ground and cleaned; and seventhly, laser augmented material restoring is conducted on a damaged structure. The method has the following advantages that the pulse welding restoring bridging capability is high, a base plate does not need to be additionally designed or manufactured, the
