1、 A brief introduction to the functions of each part of the precision spot welding machine.

1. Welding power supply: mainly used to control the size, time, waveform or temperature, voltage of the welding current output of the spot welding machine, and should be selected according to the actual application.

2. Welding transformer: By amplifying the current through welding transformer, it can be made into two structures: air-cooled and water-cooled according to the heat generation and heat dissipation conditions of the loss.

3. Welding head: Provides control pressure or displacement that affects the deformation of the workpiece and the contact resistance before discharge.

4. Welding electrode: Apply pressure and power to the welded object, and choose the appropriate material according to the actual application.

2、 Precision spot welding machines can be divided into the following four types based on their mechanical mechanisms

1. Up and down collision welding method (the most common usage of conventional up and down welding method)

2. Parallel indirect welding method (single-sided single point welding method)

3. Parallel welding method (single-sided double point welding method)

4. Parallel welding method (hot press welding method)
