| Abstract: |
| Current is an important parameter in resistance welding, and is a key point of quality control of resistance welding. In this paper, the method of current adjustment and the control of principle of three phase secondary rectifying resistance welding are described in detail. The hard ware structure and the soft ware design of the control system are introduced. Experiments show that the welding current can be adjusted in a wide range and controlled precisely with this system. |
