Wolfram Tungsten Rods

Wolfram Tungsten Rods Description

Material selection and processing

High-purity tungsten powder is used as the main raw material, and appropriate amounts of rare earth element powders, such as cerium and thorium, are added as needed.

Powder metallurgy processing: powder mixing - compression molding - high-temperature sintering - forging - drawing - cutting and turning - annealing - surface treatment - comprehensive quality inspection.

Characteristics

• High melting point, not easy to melt and deform during high-temperature welding.
• Good electrical conductivity, effective conduction of current, and high arc stability.
• Good chemical stability, not affected by corrosive media.
• Wear-resistant, creep-resistant, long service life, and environmentally friendly.

Application

1. Tungsten inert gas welding (TIG): Tungsten TIG Electrode is a non-melting electrode that melts the filler metal and the surface of the weldment through the arc generated between the weldment and the electrode, thereby obtaining a high-quality weld. It is not only suitable for welding various metal materials such as stainless steel, aluminum alloy, copper alloy, titanium alloy, etc., but also can be used in aerospace, shipbuilding, pressure vessels, pipeline installation, and other fields that require high welding quality.
2. Plasma arc welding: It has a fast welding speed and good weld quality. It is often used to weld some refractory metals and thick plate materials, such as nickel-based alloys and alloy steels.
3. Electronic devices: Cutting Tungsten Rod is often used as an electrode material and is used in electronic vacuum components such as electron tubes and vacuum switches. It can effectively withstand the impact of high voltage and high current to ensure the stable operation of electronic devices.
4. Precision semiconductor manufacturing: They can be used in processes such as ion implantation and etching to generate high-energy ion beams, engrave precise circuit patterns, and improve the performance of semiconductor devices.
5. Vacuum Melting: In a vacuum melting furnace, a TIG Welding Tungsten Rod is used to generate an electric arc, heat and melt rare metal or precious metal raw materials.
6. Glass Melting: It is used as electrode material in glass melting furnaces, which improves the melting efficiency and quality of glass, and is widely used in the production of flat glass or special glass, etc.
