| Abstract: | A novel square wave AC GTAW inverter was produced to deal with welding alumium,magnesium and their alloys.A simple topology of circuit was adopted in the latter inverse stage and a new method of re ignition in AC welding arc was used to get stable arc in welding process. Experiment showed that this power source had multifunction and met the need of welding aluninium,magnesium and their alloys well. |
