Tungsten Electrode in Arc Cutting
Tungsten electrodes are non-consumable electrodes used in tungsten arc cutting and related high-temperature arc processing equipment. They are primarily applied for cutting and gouging stainless steel, carbon steel, copper alloys, nickel-based alloys, and other electrically conductive metals. Since arc temperatures exceed 5,000°C, the electrode must provide excellent electron emission capability, high-temperature stability, and arc erosion resistance. Rare-earth tungsten electrodes have therefore become important electrode materials for arc cutting applications.
1.Applications of CTIA’s Tungsten Electrodes in Arc Cutting
Tungsten electrode establishes a stable arc with the workpiece, with arc temperatures reaching 5000–20000°C. The high-energy arc rapidly melts localized metal on the workpiece, and auxiliary gases such as compressed air or argon blow the molten metal away from the kerf to achieve material cutting. Tungsten has a high melting point of 3422°C, delivering excellent high-temperature strength and electron emission performance, which maintains arc stability and good cutting quality under high-temperature arc environments.
2.Types and Characteristics of CTIA’s Tungsten Electrodes in Arc Cutting
CTIA’s tungsten electrodes have the following types and characteristics:
