Spot welding of different metals-Nickel and monel metal
While spot welding these materials, the settings are to be properly maintained. Welding time, in this case, is only 50 % of the time for spot welding mild steel sheets or the same thicknesses. The mechanical pressure applied for spot welding of these metals is only half of that required for mild steel because the metal will get damaged if subjected to stresses in the heated condition. Also, adequate support has to be given while welding. Upto 6 mm sheets can be welded.
