Tungsten Copper Resistance Welding Electrode
1. What's Tungsten Copper Resistance Welding Electrode?
Tungsten copper resistance welding electrode is conductive electrode used in resistance welding to transfer current and pressure to metal workpieces, generating resistance heat for joining. CTIA's tungsten copper resistance welding electrodes combine tungsten's high melting point, hardness, and heat resistance with copper's electrical and thermal conductivity, helping reduce electrode softening, material pickup, and wear. They are suitable for spot welding, projection welding, butt welding, and seam welding.
2. Characteristics of CTIA's Tungsten Copper Resistance Welding Electrode
(1) High-Temperature Resistance and Anti-Ablation: Capable of withstanding elevated welding temperatures, reducing working face erosion caused by extreme heat and suiting operating conditions that generate high heat inputs.
(2) High Hardness and Good Wear Resistance: High hardness helps electrodes resist wear and compression deformation during repeated welding cycles, extending service life.
(3) Good Electrical and Thermal Conductivity: Copper helps conduct welding current and dissipate heat. CuW75 has electrical conductivity of approximately 38% IACS, while CuW80 is approximately 34% IACS. Higher tungsten content generally increases hardness and resistance to thermal erosion but reduces electrical conductivity.
(4) Anti-Sticking and Minimal Face Loss: Reduces electrode-to-workpiece sticking and material transfer issues, lowering working face loss and decreasing dressing or replacement frequencies.
(5) Good Dimensional Stability: Low thermal expansion helps limit dimensional changes during repeated heating, maintaining electrode geometry and welding contact positions.
(6) Diverse Shapes and Custom Designs: Available in rod, cylindrical, block, disc, and special structural forms, customized to welder interfaces, workpiece geometries, and welding positions.
3. Applications of CTIA's Tungsten Copper Resistance Welding Electrode
(1) Resistance Spot Welding: Used for spot welding of stainless steel, coated steel sheets, and other metal sheets, helping reduce electrode softening, material pickup, and working surface wear during welding.
(2) Resistance Seam Welding: Used for seam welding of metal sheets, containers, and strips. Depending on weld geometry and equipment design, tungsten copper electrodes or tungsten copper working-surface inserts can be used.
(3) Resistance Projection Welding: Used for welding nuts, studs, and metal workpieces with projections. Tungsten copper working surfaces help reduce compression damage and wear under high welding pressure.
(4) Resistance Butt Welding and Flash Butt Welding: Used for end-to-end joining of metal bars, wires, and profiles, such as reinforcing bars, metal rods, and strips. Tungsten copper electrodes help withstand high temperatures and wear during welding.
(5) Automotive Component Welding: Used for resistance welding of automotive sheet metal, structural components, and connecting parts, helping reduce electrode wear caused by repeated welding and lower the frequency of dressing and replacement.
(6) Welding of Special Metals: Used for resistance welding of copper alloys and other metal workpieces. When conventional copper alloy electrodes are prone to material pickup or wear, tungsten copper electrodes can be selected according to workpiece materials and welding conditions.
