Resistance welding

Resistance welding is a fundamental technology in many industrial sectors, exploiting the heat generated by electrical resistance to join metal components. A.T.S. Lamberti, with its complete range of welding equipment and components, is a reliable partner for professionals working in metal carpentry, sheet metal working and numerous other industrial applications. Let us therefore delve into the principles and solutions that make resistance welding an optimal choice for these processes.

Working principles of resistance welding

Resistance welding is based on the generation of heat by the Joule effect, which occurs when an electric current passes through the materials to be joined, which are placed under pressure. The heat generated at the point of contact between the metals brings them to a plastic or molten state, enabling a strong joint. The electrodes used for welding are essential for concentrating the current and applying the correct pressure. Key parameters include:

• Electrical current: adapted to the type of material and thickness.

• Welding time: crucial to avoid faulty joints or weaknesses in the material.

• Electrode pressure: to ensure correct fusion without excessively deforming the parts.
