Application

With the development of industries such as aerospace, electronics, automotive and household appliances, resistance welding is becoming more and more widely valued. [4] At the same time, higher demands are being placed on the quality of resistance welding. Happily, the development of microelectronics technology in China and the development of high power SCRs and rectifiers has provided the conditions for the improvement of resistance welding technology. China has produced secondary rectifier welding machines with excellent performance. Control boxes made up of integrated circuits and microcomputers have been used for the matching of new welders and the renovation of old ones. Constant current, dynamic resistance, thermal expansion and other advanced closed-loop monitoring technology has begun to be applied in production. All this will help to improve the quality of resistance welding and expand its application areas.
