Use a pure tungsten or zirconiated tungsten electrode when AC welding aluminum. Don't use a 2 percent thoriated tungsten electrode. Make sure you use a tungsten electrode large enough in diameter to carry the welding current you plan to use. Remember that AC welding requires larger–diameter tungsten electrodes.Feb 27, 2003
What color tungsten is used for welding aluminum?
Pure Tungsten (Color Code: Green) Pure tungsten also provides good arc stability for AC sine wave welding, especially on aluminum and magnesium. It is not typically used for DC welding because it does not provide the strong arc starts associated with thoriated or ceriated electrodes.Mar 7, 2006
Is Lanthanated tungsten good for aluminum?
You can use blue lanthanated tungsten as an all-purpose option with a variety of metals, including nickel alloys, aluminum, cobalt, copper, carbon steels, and titanium.
Is e3 tungsten good for aluminum?
Their main areas of application are the welding of non-alloyed and high-alloyed steel, aluminum, titanium, nickel, copper and magnesium alloys. These electrodes are also suitable for use in micro-plasma welding. ... The overall service life and current carrying capacity is lower than the E3® electrodes.
What color tungsten is best for aluminum?
If you are AC TIG welding aluminum for the first time we would suggest using a 2% ceriated in 3/32. Two solid options include Blue Demon or Weldcraft. Ceriated is the most popular choice due to the easy arc start at low amperages.
