Method for splicing thin-wall metal blanks through laser metal deposition

The invention belongs to the technical field of laser additive manufacturing, and provides a method for splicing a thin-wall metal blank by adopting laser metal deposition, which comprises the following steps: determining a blank splicing overall forming scheme; thin-wall metal blanks needing to be spliced are selected; the width of a laser metal deposition splicing area is determined; determining a material of the laser metal deposition splicing area and a base body to which the material is attached; determining process parameters of laser metal deposition; a splicing area is printed through laser metal deposition; the total layer number of laser printing is determined according to the thickness of the splicing area and the single-layer deposition height, and deposition printing is conducted layer by layer; and performing post-treatment on the thin-wall metal blank. The problems that when a traditional welding seam is used for connecting the thin-wall metal blank, the material performance of a welding seam a
