What is the best tungsten to use 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.
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.
What tungsten do you use to weld aluminum?
- 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.
- Let the tungsten form a round ball on the end.
How do you choose a tungsten electrode?
Tungsten Preparation The diameter of the balled end should not exceed 1.5 times the diameter of the electrode (for example, a 1/8-in. electrode should form a 3/16-in. diameter end), as having a larger sphere at the tip of the electrode can reduce arc stability and/or fall off and contaminate the weld.18 Jul 2016
What tungsten is used for welding aluminum?
For these reasons, pure tungsten or zirconiated tungsten are recommended for aluminum welding. In addition, the electrode diameter for AC welding has to be significantly larger than when using DC. It is recommended to start with an electrode that is 1/8" and adjust as needed.
Is E3 tungsten good for aluminum?
E3 Electrode Features and Benefits: Universal and suitable for all applications for DC and AC welding pf non-alloyed and high-alloyed steel, aluminum, titanium, nickel, copper, and magnesium alloys.
