Abstract
The invention aims at solving the problems in the prior art, and provides a tray machining technology. Compared with the traditional metal machining technology process, the technology process has primary cleaning and secondary cleaning steps. Oil stains and dirt on the surface of a welding component are well removed, the welding strength is improved, and meanwhile the attractiveness of the welding component is improved. The welding steps are divided into the primary welding and the secondary welding. Spot welding is adopted by the primary welding and is used for moulding a general shape, full welding is adopted by the secondary welding and is used for welding and strengthening, and therefore the welding deformation is effectively avoided.
