At a certain time, the resistance of the workpiece depends on its resistivity. Therefore, resistivity is an important property of the material to be welded. Metals with high resistivity have poor conductivity and metals with low resistivity have good conductivity. Therefore, when spot welding stainless steel, the Heat is easy but heat dissipation is difficult. When spot welding aluminum alloy, heat generation is difficult but heat dissipation is easy. When spot welding, the former can use a small current, while the latter must use a large current. The resistivity depends not only on the type of metal, but also on the heat treatment of the metal.
