TIG tungsten electrode refers to the tungsten electrode used in Tungsten Inert Gas (TIG) welding. TIG welding is an arc welding process in which a non-consumable tungsten electrode is used to create an electric arc, and the melting between the weldment and the welding material is carried out by an inert gas (usually argon).
Here is some key information about TIG tungsten electrodes:
1. Material: TIG tungsten electrode is usually made of pure tungsten or tungsten alloy. Pure tungsten tungsten electrodes are suitable for welding non-ferrous materials such as stainless steel and aluminum, while tungsten alloy tungsten electrodes may contain added alloying elements to improve their properties, such as tungsten-molybdenum alloy or tungsten-cobalt alloy.
2. Non-consumable: Unlike some other arc welding processes, the tungsten electrode used in TIG welding is non-consumable. This means that during the welding process, the tungsten electrode does not melt or be consumed, but is used to maintain the arc and provide heat energy.
3. High melting point: One of the main advantages of tungsten is its high melting point, which allows it to remain stable at high temperatures and suitable for extreme conditions during welding.
4. Inert gas: In TIG welding, an inert gas (usually argon) is used to protect the welding area from atmospheric contamination while providing a stable arc.
5. Application: TIG welding is widely used to weld high-quality materials that require high welding quality and appearance, such as stainless steel, aluminum, nickel alloy, etc. TIG welding is often used in aerospace, automobile manufacturing, food industry and other fields.
