Sheet metal technology needs to master the rational use of materials, size and length matching, assembly methods of spare parts, arrangement and loading, cutting straight lines and arcs, learning the convex and concave, warping and warping correction of sheet metal, and the common methods of sheet metal, bending, edging, edging, undercut and correction. Painting needs to master and pay attention to the grinding method, covering materials selection, dust removal and cleaning technology and problems in the process.
