The sheet metal cabinet processing requires various processing techniques, which is relatively complex and demanding compared with other processing industries. Particular attention is required when Welded Sheet Metal Cabinet is being welded. So let's take a look together at what issues need attention during the welding of sheet metal cabinets.
1. Follow welding operation specifications and try to eliminate welding stress as much as possible. Fixtures should be used during welding to prevent parts from being deformed by welding. If necessary, the workpiece should be corrected after welding.
2. During the welding of sheet metal cabinets, welding slag and arc damage to other non-welded parts of the components must not occur. After welding, the slag should be removed, including scraping off various particles of spattered welding filler adhering to the surface of the components.
3. Welds in sheet metal cabinets should be firm and reliable, and the solder on the outer surface of components should be filled in place without leaving gaps.
4. The welds on the cabinet in sheet metal processing should be neat and uniform, without cracks, undercut, notches, burn-through, slag inclusions, pores, weld beads, pits, and other defects. These defects must not appear on the outer surface of the cabinet, and the inner cabinet should not show them too obviously.
5. During welding, the outer surface of components should be ground and polished flat after welding, with a surface roughness value of 12.5. If the welded surfaces are in the same plane, no protrusion or depression should be visible to the naked eye after treatment.
