Resistance spot welding

2 min read

In the resistance welding field, the use of suitable spot welding electrodes is essential to guarantee the quality of the welded joint, the durability of the tool and the efficiency of the production process.

A.T.S. Lamberti offers a complete line of copper alloy electrodes with Tungsten or Molybdenum inserts, designed for high-performance applications where strength, precision and operational continuity are required.

Electrodes with Tungsten insert consist of a highly conductive copper body (such as CuCr1Zr or CuCoBe) and a tungsten or molybdenum tip, which is welded or brazed.

This configuration combines the advantages of both materials: copper ensures effective electrical and thermal conductivity, while tungsten offers mechanical strength, hardness and dimensional stability even at high temperatures.

The result is a spot welding electrode particularly suitable for welding difficult materials, such as high-strength steels, galvanised steels, stainless steels or dissimilar alloys.

The main advantages of these electrodes include high wear resistance, reduced indentation, maximum operating life, consistent weld quality and the possibility of customisation according to specific requirements.

Thanks to the stability of the active material in tungsten, it is possible to perform intensive or automated welding cycles while maintaining high performance.

Typical applications are in high-tech sectors such as automotive (including electric vehicle production), household appliance components, precision mechanics, and the production of electrical or electronic components.

Electrodes with Tungsten tip are ideal for spot, roller or resistance welding on materials of different thicknesses, where precise concentration of current and pressure is required.
