Sheet Metal Manufacturing Welding Parts,which is the combination of several parts by welding or the welding of single part to strengthen itself. There are four methods to make sheet metal welding parts, including carbon dioxide welding, argon arc welding, spot welding and robot welding. The welding method depends on practical requirement and material. carbon dioxide welding is suitable for welding of thin sheet, and argon arc welding is suitable for aluminum sheet. Robot welding is mainly used for big size parts and long welding line, such as the welding of equipment cabinet. It can save labor cost and enhance working efficiency and welding quality.

Sheet metal welding parts is the combination of several parts by welding or the welding of single part to strengthen itself.

Robot welding is mainly used for big size parts and long welding line, such as the welding of equipment cabinet. It can save labor cost and enhance working efficiency and welding quality.
With industrial development, various sheet metal welding parts burst out. What we see commonly are those made of zinc-plated steel sheet, stainless steel sheet, aluminum alloy sheet and copper alloy sheet. When operate spot welder, different metal needs different welding craft. Only by that, can the welding of each metal be done perfectly. Because of the big electrical resistance, poor thermal conduction and high thermal sensitivity of stainless steel, it should be welded with low current, high electrode pressure in short time.
The electrical and thermal conductivity of aluminum is high, therefore, when process sheet metal welding parts with aluminum alloy, high current is required and the welding should be done in short time. And because aluminum alloy will swell as temperature increasing, it is required to be welded with high electrode pressure and good flexibility of electrode. Besides, the surface will form an oxidized film, it should be cleaned carefully before welding.
