Welding Aluminium Ac Or Dc. One of the things that makes welding aluminum different than welding steel is Aluminums oxide layer. It creates a more stable arc easier welding and less spatter.
It produces a smoother welding output compared to AC. Ad Find China Manufacturers Of Aluminum Welding. DC is also used in single brazing of carbon.
The positive cycle acts as a scrubbing effect on the surface breaking up oxides that limit weld quality this is what you.
When it comes to welding most high-powered machines are run on DC or have the ability to change from DC to AC current like some professional TIG welders. While AC is used in TIG welding application in particular in the welding of aluminum DC is used in the TIG welding of stainless steel. And welding in locations where electrical outlets are limited to 110 volts only. It produces a smoother welding output compared to AC.
