摘　　要：建立了微机控制和ＩＧＢＴ逆变式脉冲ＭＩＧ焊电源系统，实现了ＭＩＧ焊接过程弧压自适应闭环控制。实验表明，该系统对弧长扰动有较强的适应能力，可在深坡口中稳定焊接。A microcomputer controlled IGBT inverter power source for pulsed MIG welding is developed.It realizes the self adaptive control and closed loop control of arc voltage in pulsed MIG welding process.Experiments show that this system has high adaptability to disturbance of arc length and guarantees the stability of welding process even in deep grooves.
