Welding fabrication of sheet metal
If you can produce a sheet metal deigned component which can be produced in one part this is nearly always the best approach. However, if you have to design a component that has two or more thicknesses of sheet metal, profile that would be materially inefficient to be CNC punched from one piece, impossible to be manufactured in one or needing water tight joints. As with spot welding; tungsten inert gas (TIG), metal inert gas (MIG) or gas welding enables you to bring these parts cut from sheet metal together into one fabrication. You have to be aware that a physical witness of the welding process will be seen and a heat affected zone (H.A.Z.) which will be visible as a burn mark on either side of the weld on the surface of the sheet metal. The weld line can be cleaned back to the parent sheet metal and if the part is painted or polished the welded joint can be be made invisible in the final sheet metal fabrication.
