Tungsten Copper as Resistance Welding Electrodes
Resistance welding—including spot welding, seam welding, and projection welding—is widely used in automotive, home appliance, electronics, and aerospace industries to join high-strength steels, stainless steels, coated metals, and various alloys. As a core component in the welding process, the electrode plays a decisive role in weld quality, productivity, and service life. Tungsten copper (W-Cu) alloys, known for their excellent conductivity, high-temperature resistance, anti-adhesion, and mechanical strength, are essential materials for high-performance resistance welding electrodes.

Key Advantages
1.High Hardness and Arc Resistance
The tungsten phase delivers superior hardness and a melting point of 3410°C, enabling the electrode to resist deformation and melting under high temperatures and arc discharge conditions.
2.Excellent Electrical and Thermal Conductivity
Copper ensures smooth current flow and fast heat dissipation, improving welding efficiency and consistency of the weld nugget.
3.Strong Anti-Adhesion Properties
W-Cu electrodes are less prone to sticking to the workpiece, reducing spatter, minimizing cleaning frequency, and enhancing automation reliability.
4.High Mechanical Strength with Minimal Deformation
Well-suited for high-pressure welding environments and continuous robotic operations where shape retention and mechanical durability are essential.
Typical Applications
1.Automotive Industry: Spot and projection welding of structural components, high-strength steel panels, and galvanized steel; compatible with robotic welding systems.
2.Home Appliances & Electronics: Precision spot welding of thin metal connectors, heat sinks, and structural joints.
3.Aerospace & Defense: Welding of strong alloy parts and dissimilar metal joints, where high durability and process stability are required.
4.Battery Manufacturing: High-frequency welding of battery tabs, shells, and conductive strips in EV and energy storage systems.
