Among many welding equipment, spot welding machines are more popular, and the reason why spot welding machines are so popular is inseparable from their own welding advantages. Let ’s take a look with Chengdu electric welding machine manufacturer Xiaobian:
1. When the nugget is formed, it is always surrounded by a plastic ring, the molten metal is separated from the air, and the metallurgical process is simple.
2. The heating time is short and the heat is concentrated, so the heat affected zone is small, and the deformation and stress are also small. Normally, no correction and heat treatment processes need to be arranged after welding.
3. There is no need for filler metals such as welding rods and wires , and welding materials such as oxygen, acetylene, and argon, and the welding cost is low.
4. Simple operation, easy to realize mechanization and automation, and raise working conditions.
5. High productivity and no noise and harmful gas. In mass production, it can be programmed on the assembly line with other manufacturing processes, but flash butt welding needs to be separated due to sparks.
