Product Features
Pure tungsten offers excellent high-temperature stability and strong resistance to deformation under repeated current and pressure. This makes the electrode suitable for demanding resistance welding processes where the working surface must remain stable during continuous production.
Compared with conventional copper-based electrodes, pure tungsten provides better resistance to wear and thermal impact in applications that require a durable contact surface.
The saddle-shaped contact surface improves electrode positioning during lap welding. Its curved geometry helps the electrode match the workpiece more securely, reducing the risk of sliding, offset contact, or uneven pressure.
This design is especially useful when welding small parts, curved components, narrow contact areas, or workpieces that require accurate electrode alignment.
The arc-shaped working surface helps distribute welding force more evenly across the contact area. Better pressure distribution supports more consistent heat input, helping improve weld stability and reduce variation between welding cycles.
This is important for applications where repeatability and stable joint quality are required.
The electrode is produced through mechanical machining to ensure accurate dimensions, clean edges, and a stable contact surface. Precision machining allows the electrode to fit customized fixtures and welding equipment more effectively.
The 40 × 10 × 6 mm structure can also be adjusted according to customer drawings and actual welding conditions.
The saddle shape, curvature, thickness, and overall geometry can be customized according to the welding fixture, workpiece structure, and required contact area. This allows the electrode to meet different welding process requirements in industrial production.
