The surface of the precision sheet metal workpiece should be flat and free of any burrs, bumps and cracks. For riveting parts, it is: riveting nuts, riveting screws, rivet nuts and riveting nuts, etc., when the parts are pressed, the threads cannot be deformed. After the pressure riveting, the pressure riveting area should be no deformation, the pull bag height, wall thickness should be uniform, and the top should not have any burr. In terms of welding, manipulator sheet metal processing requires:

1. the weld seam should be firm and uniform, and there should be no defects such as virtual welding, cracks, welding penetration, gaps and undercuts.

3. The length and height of the weld cannot exceed the allowable requirements of the sheet metal workpiece.

4. The length of the welding spot is 8-12mm, and the distance between the two welding spots should be 50mm.

5. If there are special requirements for welding points on the drawings, the drawings shall be followed.

6. After welding, the outer surface of the part shall be free of defects such as slag inclusion, air hole, weld bead, protrusion and depression, and the inner surface defects shall not be obvious and shall not affect the assembly. Important parts such as door panels and panels should also remove post-weld stress to prevent deformation of the workpiece.

7. The outer surface of welded parts shall be ground flat. For powder spraying parts and electroplated parts, the grinding roughness after welding shall be Ra3.2 ~ 6.3, and the painted parts shall be Ra6.3 ~ 12.5.
