1. Fusion welding
When welding using this method, the joint of the weldment needs to be heated to a molten state without applying pressure. There are many fusion welding methods, which can be divided into arc welding, gas welding and electroslag welding lamps.
2. Pressure welding
In this method, during the welding process, pressure needs to be applied to the weldment to complete the welding of the nut. Commonly used pressure welding methods include resistance welding, ultrasonic welding and friction welding. Each welding method has different practices.
3. Brazing
This method uses metal materials with low melting points to heat the weldment to a certain temperature to complete the nut welding work.
