Because the heat generated by resistance is directly proportional to the square of current, the welding current of medium frequency spot welder is the most important factor of heat generation. The importance of welding current is not only the magnitude of welding current, but also the magnitude of current density.

The products of many industries can't be integrated. They need to be welded later. We need to use stainless steel spot welder to weld. When using stainless steel spot welder to weld workpiece, the choice of electrode material and shape is very important, which directly determines the welding effect.

Stainless steel spot welder is a very mature welding equipment, but there are still many users do not know it so well, so how to judge the welding performance of stainless steel spot welder? Let Xiaobian talk about it for you.

The electrode pressure of stainless steel spot welding machine is also one of the important parameters of spot welding. If the electrode pressure is too large or too small, the bearing capacity of the welding spot will be reduced and the dispersibility will be increased, especially the tensile load. When the electrode pressure is too small, due to the lack of plastic deformation range and deformation degree of the metal in the welding area, the heating speed will be caused by the excessive current density and the expansion speed of plastic ring will be heavy rain, resulting in serious splashing.
