What tungsten do I use for TIG welding aluminum?
In summary, follow these three recommendations: 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.
What color tungsten is used for welding aluminum?
Green
Pure Tungsten (Color Code: Green) Pure tungsten also provides good arc stability for AC sine wave welding, especially on aluminum and magnesium.
Is Blue tungsten good for welding aluminum?
They are coded in blue and are extremely useful in welding alloys, especially aluminum.
What is 1.5% Lanthanated tungsten used for?
1.5% Lanthanated (Gold) Electrodes Lanthanated (Gold) Electrodes perform well in AC applications and are great for welding titanium alloys, copper alloys, nickel alloys, and stainless steel.
What is 2% Lanthanated tungsten used for?
What Are Lanthanated Tuingstens Used For? Lanthanated tungsten can be used for all of the DC welding applications with excellent arc stability at low amperages while maintaining its sharp point well and minimal burn rate in high amperage situations.
What is 2% Ceriated tungsten used for?
2% Ceriated Tungsten is best for use in alternating current (a/c) or direct current (d/c) applications using inverter or transformer based constant current power sources. Good for low-alloyed steels, non-corroding steels, aluminum alloys, magnesium alloys, titanium alloys, nickel alloys, copper alloys.
What do the different colors on tungsten mean?
Color code and what it means Green (EWP) = Pure Tungsten. Orange (EWCe-2) = 2% Ceriated. Red (EWTh-2) = 2% Thoriated. Gold (EWLa-1.5) = 1.5% Lanthanated. Brown (EWZr-1) = 1% Zirconiated (sometimes also sold as white tungsten)
What do TIG tungsten colors mean?
Color code and what it means The main colors/varieties of TIG electrodes and their American Welding Society abbreviation are as follows: Green (EWP) = Pure Tungsten. Orange (EWCe-2) = 2% Ceriated. Red (EWTh-2) = 2% Thoriated. Gold (EWLa-1.5) = 1.5% Lanthanated.
What is E3 tungsten used for?
E3 Electrode Features and Benefits: Excellent ignition and consistent welding properties. 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. Reliable and usable for automated welding.
