Tungsten Copper Electrode in Electric Riveting
Tungsten copper electrode is a composite electrode specifically designed for electric riveting. Electric riveting uses short-duration, high-current pulses to generate resistance heat, bringing localized areas of the workpiece to a plastic or semi-molten state. The workpiece is then upset, riveted, or formed under electrode pressure. During this process, the electrode is subjected to high current density, high upsetting pressure, and repeated heating and cooling cycles. These conditions can cause the electrode tip to soften and deform, while plasticized workpiece material may adhere to its working surface. The electrode therefore requires good electrical and thermal conductivity, resistance to material pickup, and resistance to deformation. CTIA's tungsten copper electrode combines tungsten's high melting point, hardness, and resistance to material pickup and deformation with copper's electrical and thermal conductivity. It helps maintain tip geometry under high-current, high-pressure, and thermal cycling conditions, extending electrode service life. It is particularly suitable for electric riveting and upsetting of bolts, screws, pins, and similar components.
