The design of inverter electro-fusionweld machine based on PIC SCM was described. The IGBT inverter power control system, including hardware and software were given.
The weld defects of incomplete fusion and burn through always occur when the electro-slag welding is used between the outside thin metal plate and the inner clapboard in a box-section member.
