What color tungsten is for aluminum?

Pure Tungsten (Color Code: Green)

Pure tungsten also provides good arc stability for AC sine wave welding, especially on aluminum and magnesium.

Can you use GREY tungsten on aluminum?

However, pure tungsten electrodes can only be used in DC for welding aluminum. 2.) 2% ceriated: Seen in the grey coloured label, these electrodes consist of 2% cerium. Usually, these electrodes are used for aluminum in lower amperage DC welders.

Is purple tungsten good for aluminum?

This rare earth tungsten offers excellent ignition characteristics and consistent welding properties. They are universal and suitable for all applications in the whole range of AC and DC welding of non-alloyed and high-alloyed steel, aluminium, titanium, nickel, copper and magnesium alloys.

What do the 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 color tungsten do I need?

The color most manufacturers choose to use is purple. Depending on the mixture, rare-earth tungsten electrodes can have very different characteristics. For example, they can provide a stable arc when working with DC or AC current, the ability to withstand high amperages or greater longevity.

How to choose the correct Tungsten for TIG Welding

What is GREY tungsten used for?

Grey electrodes perform well in DC applications and are great for welding titanium, copper, magnesium, aluminum, and nickel alloys, as well as non-corroding and stainless steels.

What is the best tungsten for TIG welding aluminum?

If you are AC TIG welding aluminum for the first time we would suggest using a 2% ceriated in 3/32. Three solid options include Blue Demon , Weldcraft or CK. Ceriated is the most popular choice due to the easy arc start at low amperages.

Is E3 tungsten good for aluminum?

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.

What type of tungsten is GREY?

EWCe-2 tungsten electrode is currently color-coded with a gray band, although in the past it was color-coded with an orange band. It is quite similar to EWLa-2 in that it has excellent current carrying ability, excellent arc starting ability, and can last through many different arc start and arc termination cycles.

Can you use red tungsten on 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. Remember that AC welding requires larger–diameter tungsten electrodes.

What is blue tungsten used for?

Blue is made with tungsten and lanthanum with lanthanum being at 2%, giving it the name 2% lanthanated tungsten. 2% (blue) can be used with both AC and DC. It has a simple arc for startup and warming up and can be used with both AC and DC with no issues.

What is red tungsten used for?

The most commonly used tungsten in the United States. This tungsten is used primarily in DC welding. It has a low work function and provides a high load and amperage capability.

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.

How do you round tungsten for aluminum?

What is purple tungsten made of?

Rare Earth (Purple) Electrodes

The innovative Rare Earth Blend tungsten electrode contains 98.34% tungsten, 1.5% lanthanum, 0.08% Zirconium, and 0.08% Yttrium.

What color tungsten do you use to TIG weld aluminum?

Green TIG Welding electrodes are pure Tungsten and are used for AC welding, often for aluminum and magnesium. They tend to be commonly used because they are inexpensive. However, they also burn up much faster than the other alloy electrodes, so prepare to stock up if you go this route.

What is 2% 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 is red tip tungsten?

2% Thoriated Tig Tungsten Red Tip

This tungsten electrode is used in the Tig Welding process and is the most used tungsten within the range of tungsten electrodes available.

How do you choose a tungsten electrode?

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. In any application, the type and shape of tungsten you use helps determine the arc quality and welding performance you will achieve.

What is white tungsten?

Tungsten carbide rings are naturally a grayish color. They can be plated with platinum group metals to make them have the same color as platinum. These types of tungsten rings are called white tungsten rings.

What color is pure tungsten?
