More info
The item you've specified, a 150mm GREY TIG TUNGSTEN ELECTRODE - ALLOY / STAINLESS STEEL - 2.4mm, is a specific type and size of non-consumable electrode used in Tungsten Inert Gas (TIG) welding (also known as Gas Tungsten Arc Welding or GTAW).
Here's a breakdown of what each part of the description means:
Electrode Specifications
| Term |
Meaning |
Detail |
| TIG Tungsten Electrode |
Purpose |
Used in TIG welding to create the electric arc. It is non-consumable, meaning it doesn't melt into the weld puddle. |
| GREY |
Composition/Type |
The color code Grey typically identifies 2% Ceriated Tungsten (AWS Classification: EWCe-2). Ceriated electrodes contain approximately 1.8–2.2% Cerium Oxide ($text{CeO}_2$). |
| 150mm |
Length |
The standard length of the electrode rod, which is about 6 inches. |
| 2.4mm |
Diameter |
The diameter of the electrode, which is approximately $3/32$ of an inch. The diameter determines the suitable amperage range for welding. |
| ALLOY / STAINLESS STEEL |
Recommended Use |
Grey/Ceriated electrodes are highly recommended for DC (Direct Current) welding, which is the standard setup for welding stainless steel, carbon steel, nickel alloys, and titanium alloys. They are also versatile and can be used for AC (Alternating Current) welding on aluminum alloys, especially at lower currents. |
Key Benefits and Applications
Grey (2% Ceriated) tungsten electrodes are very popular due to their versatile and high-performance characteristics.
-
Non-Radioactive: They are a common, safer alternative to the slightly radioactive Thoriated (Red) electrodes.
-
Excellent Arc Starting: They feature exceptional arc starting and re-ignition properties, especially at low amperages. This makes them ideal for precision work and automated/orbital welding.
-
Low Amperage Performance: They perform very well at lower current ranges, which is suitable for thin sheet metal, pipes, and small, delicate parts.
-
Versatility: They can be used successfully with both DC (Direct Current) and AC (Alternating Current) processes, particularly when using inverter or transformer-based power sources.
The 2.4mm diameter is a common size suitable for a wide range of medium-amperage TIG welding tasks.
