2.4mm 3.2mm 4.0mm Pure Tungsten Electrodes Polished For Tig Welding

Pure tungsten electrode is a kind of electrode product with refractory metal tungsten as the main raw material, it is the earliest electrode used in TIG welding, but due to the high electron escape work, high tip temperature and easy grain growth of this electrode, it leads to difficulty in starting the arc, unstable arc beam and short service life, so the application field is limited, basically used in AC welding. Some researchers have pointed out that some modifiers such as rare earth oxides can be added to the pure tungsten production process, which will enable the prepared electrode products to have a higher overall performance and a wider range of applications.

In practical applications, 2.4mm, 3.2mm, and 4.0mm pure tungsten electrodes are primarily used for welding non-ferrous metals such as aluminum and magnesium. They are widely employed in industries like aerospace, automotive manufacturing, electronics, and pipeline welding. For example, in the aerospace sector, these electrodes are used to weld aluminum alloy components, ensuring high strength and reliability of the welds. In automotive manufacturing, they are utilized for welding aluminum alloy body parts, such as engine hoods and doors, to meet high-quality welding requirements.

Features

High Melting Point and Stability: Pure tungsten electrodes have an extremely high melting point (approximately 3422°C), allowing them to remain stable in high-temperature welding environments without melting or eroding easily. This ensures consistent performance over prolonged welding operations, reducing the frequency of electrode replacement and improving welding efficiency.

Excellent Contamination Resistance: When welding oxidation-prone metals like aluminum and magnesium, pure tungsten electrodes resist contamination and maintain a stable arc. Even if exposed to minor impurities during welding, the electrode surface quickly self-cleans, minimizing welding defects such as porosity and inclusions.

Arc Stability: Pure tungsten electrodes deliver exceptional arc stability in AC welding. They produce a uniform and steady arc, ensuring consistent weld penetration and width, resulting in high-quality, aesthetically sound welds. This stability is particularly crucial for welding thin materials, effectively preventing issues like burn-through or lack of fusion.

Low Radioactive Contamination: Unlike tungsten electrodes containing radioactive elements such as thorium or cerium, pure tungsten electrodes are free of radioactive materials, making them more environmentally friendly and safer. This not only protects the health of operators but also aligns with modern industrial environmental standards, making them ideal for workplaces with stringent safety requirements.

Versatility in Welding Processes: Pure tungsten electrodes are not only suitable for traditional AC welding but can also be used in certain DC welding applications. Their broad compatibility makes them a versatile welding material, capable of meeting the demands of diverse welding scenarios.

Applications

Aerospace Industry: In the manufacturing of aircraft components, welding lightweight yet high-strength materials like aluminum alloys is often required. Pure tungsten electrodes meet the stringent demands for welding quality and precision, ensuring strong and reliable welds.

Automotive Manufacturing: During the production of vehicle bodies, numerous aluminum alloy parts-such as engine hoods and doors-require welding. The use of 2.4mm, 3.2mm, and 4.0mm pure tungsten electrodes enables high-quality welding of aluminum alloys with varying thicknesses.

Electronics Industry: In the fabrication of electronic devices, small aluminum alloy components often necessitate the use of thinner-diameter pure tungsten electrodes, such as 2.4mm, to achieve precise welding control.

Pipeline Welding: In industries with extremely high welding quality standards-such as nuclear, pharmaceutical, and chemical processing-pure tungsten electrodes are used to weld stainless steel pipelines, ensuring leak-proof and corrosion-resistant seams.
