摘要
本文从提高不锈钢焊接速度的需要出发,分析了提高焊速的途径,成功地设计了两种晶体管电源:模拟型和低频加高频 PWM 调制型电源。由于采用串列电弧的形式,使不锈钢焊管的焊速能明显提高。
In order to increase the welding speed of welding stainless pipe,a transistor switch power source has been designed successfully.The power source has two types:analogue type and chopper-type in which low frequence wave mixed PWM high frequence wave.Because it uses serial double arc type,the welding speed of welding stainless pipe has been increased.
