How To Weld Aluminium With Dc Tig. Its designed primarily for oxy-fuel welding aluminum but TIG. DC TIG aluminum welding is possible with a DCEN setting and pure helium.
Since much heat goes back into it a smaller-diameter tungsten electrode with a pointed tip works very well. This page focuses on welding aluminum with a DC TIG welder electrode negative DCEN argon and flux. DC TIG aluminum welding is possible with a DCEN setting and pure helium.
This is because aluminum has basically two layers the base aluminum and aluminum oxide.
The flux cleans oxides from the aluminum and it helps shield the molten puddle. Choose the Right TIG Welding Application for DC Power. TIG welding aluminum with a DC current. This page focuses on welding aluminum with a DC TIG welder electrode negative DCEN argon and flux.
