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 GREY tungsten?

The 2% Ceriated Tungsten from CK is best at low amperage ranges. It offers good ignition and re-ignition properties, long service life and excellent arc stability.

Can you weld aluminum with GREY tungsten?

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 for what?

Pure Tungsten (Color Code: Green)

These electrodes form a clean, balled tip when heated and provide great arc stability for AC welding with a balanced wave. Pure tungsten also provides good arc stability for AC sine wave welding, especially on aluminum and magnesium.

What is the best tungsten for stainless steel?

What color tungsten is for stainless steel? The red TIG tungsten is the most commonly used electrode because the 2% thorium mixed with the tungsten is durable and versatile. The thorium allows for easier arc starts and higher current-carrying capacity.

How to choose the correct Tungsten for TIG Welding

What size tungsten do I need to weld aluminum?

The Electrode Size for TIG Welding Aluminum

You often need to consider a 1/8” electrode for welding aluminum in order to get enough heat and to create a stable arc. Too small an electrode will create a sloppy weld. If you're working on AC with a lanthanated electrode, you may be able to use a 3/16” or 3/32” electrode.

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 color tungsten is best for stainless?

Orange Ceriated TIG Welding Electrodes contain about 2% percent ceriated and are ideal for DC welding and lower current processes. 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.

What tungsten do I use 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 can I weld with gray tungsten?

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 all around tungsten for TIG welding?

Ceriated and lanthanated tungstens hold up better for AC TIG applications than 2% thoriated tungsten. While thoriated tungsten remains the most common in DC TIG, because of concerns about radiation, most experts strongly recommend ceriated or lanthanated electrodes for AC and DC TIG.

What are the different colors of tungsten for TIG welding?

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 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.

What Colour is 2% Lanthanated tungsten?

EWLa-2: 2% lanthanated tungsten. The EWLa-2 tungsten electrode is color-coded with a blue band. It is known for its excellent arc starting ability, excellent current carrying ability, and can withstand many arc cycles. It can be welded as the negative electrode using direct current or with alternating current.

What color is pure tungsten?

Pure tungsten (color code: green)

What causes GREY TIG welds?

The gray is caused because the metal is too hot after the shielding gas is removed from it and the weld has absorbed impurities from the atmosphere.
