Spot welding electrode has a long service life. The key technology of non-stick electrode is the selection of electrode material, the shape of spot welding head, and the shape of electrode rod. Before designing the electrode, there are three key elements that designers need to be very clear: A) shape of the workpiece B) coating type of the workpiece C) geometric map of the workpiece welding (welding process route).

Advantages

1.Chrome zirconium copper:high hardness, wear resistance, high temperature resistance and good heat dissipation.

2.Spot welding electrode head:it does not stick to the workpiece, and the welding is firm and efficient.

3.Spot welding electrode cap:the softening temperature is high, the hardness is still high under high temperature, and the welding process is not easy to deform.

4.Spot Welding: welding iron, stainless steel, cold rolled sheet, carbon steel plate, low carbon steel, galvanized plate and so on.

Different Types of Electrodes

Selection of Workpiece Material

Most spot welding is to weld one metal to another different metal. This application requires two different electrode materials. Another problem is that the workpiece is composed of different materials. For example, the pins of many axial electronic components are steel cores, with copper coating on the outer layer and tin coating on the outer layer. In most cases, the material of the workpiece determines the selection of electrode material.

For metals with low conductivity (high resistance), such as beryllium copper, platinum, nickel and steel, copper alloy need copper alloy electrode materials with high conductivity. The electrode with high conductivity will keep the heat on the work-piece contact surface instead of generating the heat on the electrode head.

High conductivity metals such as copper, some copper alloys and silver require low conductivity electrode materials such as tungsten copper, tungsten and molybdenum. The electrode head generates high heat, which is transmitted to the work-piece contact surface.
