【Abstract】 In this paper, the lowvoltage and giant impulse current syncro welding method for 50 spots welding machine has been studied. On anlysizing low voltage and giant impulse current welding process, the experimental research has been carried out on 50 spots small scale syncro SCR switch for controlling giant impulse welding current and the technalogy of storage energy box. By application of the welding method to 50 spots welding machine. it has shown from production that the welding machine has advantages of high producticity, good welding quality and low installed capacity.更多还原
