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, Brown (EWZr-1) = 1% Zirconiated.
What color tungsten is for stainless steel?
What color Tungsten should be used for stainless steel? The thoriated red electrode is ideal for stainless steel welds. It provides the optimal heat generation, bead formation, and weld penetration to give smoother welds.
What type of tungsten is yellow?
Thoriated (EWTh-1 Yellow Stripe Electrode Classifications: Yellow Stripe; and EWTh-2 Electrode Classifications: Red Stripe) Thoriated tungsten contains thorium oxide (ThO2 or thoria), and it is the most commonly used tungsten in America.
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.What is purple tungsten?
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. Because of their great ignition properties they are also suitable for automated welding.
What is yellow tungsten used for?
1.5% Lanthanated (Gold) The gold lanthanated tungsten electrodes contain less lanthanum than their blue counterparts and are best used in DC applications. They are best for welds with titanium alloys, copper alloys, nickel alloys, and non-corroding steel.
What color is pure tungsten?
Pure Tungsten (Color Code: Green)
What is the best tungsten for mild steel?
2% Thoriated Tungsten Electrode. The 2% thoriated (color code red) is an all-purpose tungsten electrode and it’s recommended for welding mild steel because they work well on lower temperatures, which is what you need if you don’t want the steel to warp.What is GREY tungsten good 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 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. It is the perfect substitute for red thoriated electrodes.
Article first time published onWhat is purple TIG tungsten for?
Weldclass RE4 purple-tip TIG Tungsten electrodes are a high-performance all-metal tungsten. They are suitable for both DC (Steel, Stainless steel etc) and AC (Aluminium) TIG welding. Maintains tip shape, reliable arc striking, low burn off rate, long service life and smooth/stable arc.
What is E3 tungsten?
E3 Tungsten are electrodes with rare earth mixed oxides. Compared to thoriated electrodes, E3 is less harmful to the environment and not radioactive. E3 Electrode Features and Benefits: Excellent ignition and consistent welding properties. … Reliable and usable for automated welding.
What color tungsten do you 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.
What color does tungsten look like?
Most tungsten rings are gunmetal gray, however silver-white tungsten rings are readily available as well. The former has an edgy and unique appearance, whereas the latter looks similar to high-end metals such as platinum and white gold. Some jewelers sell tungsten rings in black as well.
What is white tungsten?
Tungsten by itself is a grayish powdery metal. It cannot be made into a ring unless it is combined with carbon, forming tungsten carbide. … 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 is the red tungsten used for?
2% Thoriated (Red) Electrodes Thoriated electrodes perform well in DC applications and are great for welding copper alloys, nickel alloys, titanium alloys, and stainless steel.
Can I use green tungsten for steel?
Why use green, pure tungsten electrodes? They work well on AC sine wave welding and form a solid balled tip that results in a stable arc. … Since it can weld carbon steel, stainless steel, nickel alloys, and titanium, some welders have found that it works well as a replacement for thoriated electrodes.
Why is tungsten Thoriated?
Thoriated tungsten electrodes are widely used because they make good welds and are long lasting and quite easy to use. … Other reasons for their use include easier arc initiation, reduced weld metal contamination, higher current- carrying capacity, the ability to sharpen the electrode, and long life.
What color is E3 tungsten?
3/32 in E3 (purple) Tungsten for TIG Welding.
What tungsten is used for 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.
What is E3 tungsten good for?
These tungsten electrodes are high-quality and ideal for use with both TIG and plasma arc welding applications. These tungsten electrodes are high-quality and ideal for use with both TIG and plasma arc welding applications.
Can tungsten be radioactive?
The Thorium used in 2% thoriated tungsten is a radioactive element and therefore can be dangerous to the health of those exposed to it and to the environment.
