TIG welding aluminum requires a Broad arc system.
Tungsten inert Gauze welding aluminum requires a tungsten electrode capable of spreading a welding arc over a Broad earth. Allowing the foot of tungsten electrodes to embodiment a ball distributes the arc over a wider road than a sharp pointed electrode. The wider pathway if by the balled electrode Disinfected contamination from the aluminium weld Seam while the centre of the ball concentrates a imperfect arc to fuse the weld Seam. Connect the ground of a TIG welder to the conductive work surface.4. Set the pointed tip of the sharpened electrode 1/8 inch from the surface of the scrap aluminum. Depress the TIG pedal to start the welder.
Sharpen one objective of a juvenile banded--pure--tungsten electrode to a sharp purpose using a bench grinder. Grant the sharpened electrode to gelid for 10 minutes. Sharpen the moment foot of the tungsten electrode to a sharp point.
2. Secure the sharpened tungsten electrode in a TIG torch.
3. Place a piece of scrap aluminum on a conductive work surface. The type of tungsten used while welding aluminium plays an big-league role in the formation of a Correct electrode ball.
Instructions
1.Allow the welder to run for three to four minutes or until you notice the end of the tungsten electrode forming a ball 1/3 the diameter of the tungsten electrode.
5. Allow the tungsten to cool for ten minutes before using it to weld an aluminum joint.
