Abstract:

In order to meet the requirements of the double-wire pulse metal active gas(MAG)welding,a novel soft-switching high-speed double-wire pulse MAG welding inverter,which combines the soft-switching technology,the double closed loop control technology and the can bus technology,was developed. The proposed inverter was then tested on a computer information platform. The results indicate that the novel welding inverter meets the re-quirements of high-speed double-wire pulse MAG welding well because it possesses excellent dynamic and static characteristics and reliable performance in the synchronic control between the master inverter and the slave inverter.

Key words: soft switching, double-wire pulse metal active gas welding, double closed loop control, CAN bus, synchronic control
