What do you call the part of the torch that holds the tungsten electrode?

What do you call the part of the torch that holds the tungsten electrode?

Collet: the part of the torch that holds the tungsten electrode. Electrode cap. Shielding gas nozzle: to control the gas stream. The nozzle size is dictated by the bead width and gas volume.

Which part of the TIG welding torch holds the electrode?

A clamping device called the collet is provided in the torch for holding the tungsten electrode. Collets are generally made up of copper alloys. Nozzles are provided onto the head of the torch to provide direction for the shielding gas flow. Nozzles are generally made up of ceramic materials.

How is the TIG welding torch held during the welding process?

When welding manually, once the arc is started, the TIG torch is held at a travel angle of about 15 degrees. For mechanized welding, the electrode holder is positioned vertically to the surface.

What is used as the electrode in TIG GTAW welding?

As its name implies, the electrodes used in TIG welding are tungsten electrodes. Tungsten creates a nonconsumable electrode — it has a high melting point and offers great amounts of electrical conductivity.

What should be the electrode angle while building up worn out shaft?

Answer: Strike the arc by holding the electrode perpendicular to the workpiece, whereafter the electrode should be pointed in the appropriate direction, inclined about 5–10° from the workpiece and pushed forward.

Which metal electrode is used in spot welding?

Electrode materials typically used for spot welding copper include molybdenum and tungsten.

What is GTAW welding used for?

GTAW is most commonly used to weld thin sections of stainless steel and non-ferrous metals such as aluminum, magnesium, and copper alloys.

What type of welding is GTAW?

Gas Tungsten Arc Welding
Gas Tungsten Arc Welding: GTAW Gas tungsten arc welding (GTAW) is also known as TIG welding, which stands for tungsten inert gas. Just like in GMAW welding, an inert shielding gas is used.

Can you hold electrode while welding?

You can hold the electrode when stick welding (SMAW) for a short time to improve the electrode’s stability when striking the arc or making a few tack welds. When doing so, you must wear dry welding gloves in good condition.

Which electrode is used in TIG welding?

tungsten electrode
Tungsten Inert Gas (TIG) welding, also known as Gas Tungsten Arc Welding (GTAW) is an arc welding process that produces the weld with a non-consumable tungsten electrode.

What type of electrode is used in rebuilding?

6013 electrodes are relatively easy to use. They create a softer arc that is ideal for use on sheet metal. This type of electrode is often employed for general repair on thinner materials. 6013 electrode welds offer around a 60,000 psi minimum tensile strength, according to Metal Web News.

What kind of electrode is used in GTAW?

In GTAW (Gas Tungsten Arc Welding) also known as TIG welding (Tungsten Inert Gas welding), a non consumable electrode (made up of Tungsten) is used. Tungsten is preferred due to high its high melting point (approximately 3,410 0 C) and high hardness.

What does a GTAW welding torch do for welding?

3. Welding Torch: The GTAW welding torch holds the tungsten electrode and provides the means to convey shielding gas to the molten weld pool through a nozzle. A clamping device called the collet is provided in the torch for holding the tungsten electrode.

What are the electrodes on a TIG welding torch?

GTAW electrodes are color-coded to help you distinguish them. The TIG welding torch conveys the shielding gas through a nozzle and also holds the electrode. It also has a clumping device known as a collet that holds the electrode in position.

How is a tungsten electrode held in a torch?

The tungsten (or tungsten alloy) electrode is held in a torch. Shielding gas is fed through the torch to provide an inert atmosphere that protects the electrode and the molten weld pool.
