Application of digital inverter-controlled AC pulsed MIG welding system to light metal joining

A digital inverter-controlled AC pulsed GMAW system has been developed for welding sheet metal structures. The arc is quite stable by extracting arc-length-related voltage through the intelligent filter. The synergic AC pulse control automatically adjusts wire feed speed to keep the setting current...

More Information
Summary:A digital inverter-controlled AC pulsed GMAW system has been developed for welding sheet metal structures. The arc is quite stable by extracting arc-length-related voltage through the intelligent filter. The synergic AC pulse control automatically adjusts wire feed speed to keep the setting current when the EN ratio (ratio of electronegative current integration to electrode negative plus electrode positive current integration over one pulse cycle) changes. These features make finding optimum welding conditions for gap existing joint.
