Aluminium welder processes involve an AC arc

Aluminium Welders

AC waves in Aluminium Welders allow the process of fusing aluminium components together to occur. During the GTAW process the polarity of the welding arc changes and is either removing aluminium oxide from the surface (tungsten positive) or adding heat to the weld pool (tungsten negative) . The AC tig welding process is best for aluminium welders and is only slightly exceeded by hybrid wave processes that include a DC component. The latest Hybrid wave Tig process  injects a small DC interlude between the AC cycle. When performing a weld on aluminium […]
