| Abstract: | A novel ultrafast-convert hybrid ultrasonic pulse variable polarity gas tungsten arc welding process(HPVP-GTAW) has been developed and the applicability of the HPVP-GTAW process has been studied.The experimental results show that the welding characteristics of Al-Mg and Al-Cu alloy plates are improved predominantly,compared to that of the conventional VP-GTAW process.The weld porosity is decreased and mechanical properties of welded joints produced by the HPVP-GTAW process are enhanced obviously. |

| Keywords: | aluminum alloy ultrafast-convert ultrasonic pulse current VP-GTAW welding quality |
