TIG Tungsten Electrodes

TIG TUNGSTEN ELECTRODES

Tungstens are used as a non consumable electrode in TIG welding.  Tungsten has a very high melting point, making it particularly suitable for TIG welding applications.

Here’s a guide to choosing the correct tungsten for your project:

Blue tipped – Lanthanated Tungsten:  Performing exceptionally well in both AC and DC, these tungsten electrodes are effective for welding aluminium alloys, magnesium alloys, copper alloys, titanium alloys, low alloyed steels and non- corroding steels.  A good choice as an all purpose tungsten electrode.

Green tipped – Pure Tungsten:  Least expensive tungsten type.  Good stability in AC but less used in DC TIG welding as other tungstens provide better arc starting.

Red Tipped – Thoriated Tungstens:  Thoriated tungstens can be used in DC negative or straight polarity on carbon steel, stainless, titanium and nickel.
Also suitable for speciality AC welding (such as thin gauge aluminium)

Grey Tipped – Ceriated Tungstens:  Very similar in welding characteristics to 2 % thoriated, ceriated tungstens are best used for welding carbon steel, stainless, nickel alloys and titanium.

White Tip – Zirconiated Tungstens:  Suitable for AC TIG welding only.  Produces a very stable arc when welding materials such as Aluminium.

More Useful Information About TIG Tungstens:

TIG (Tungsten Inert Gas) welding is a high-precision welding process that utilizes a non-consumable tungsten electrode to create the arc and join metal pieces together. In TIG welding, the tungsten electrode must be ground and sharpened to a specific angle to ensure a stable and well-defined arc, enabling you to achieve immaculate welds with utmost accuracy and control.

The Importance of Tungsten Sharpening in TIG Welding:
Improved Arc Stability:

A properly sharpened tungsten electrode allows for a stable and consistent arc, reducing the risk of arc wandering and resulting in cleaner welds.

Precise Weld Pool Control:

The right tungsten tip geometry allows you to maintain better control over the weld pool, enhancing the weld bead’s shape and overall aesthetics.Enhanced Weld

Quality:

With a correctly sharpened tungsten electrode, you can minimize the likelihood of defects such as porosity and tungsten inclusions, leading to higher-quality welds.

Longer Electrode Life:

Properly sharpened tungsten electrodes experience less wear and tear, leading to an extended electrode life and reduced downtime.
