Precise contact at every point: SVS standards for spot welding electrodes
Spot welding electrodes are manufactured with high dimensional precision and processed with defined tip geometries. The copper alloys used combine electrical conductivity with thermal stability and form the foundation for consistent heat input during high-frequency operation. The contact surface is designed to ensure targeted transmission of current and force into the joining zone.
Available in standardized geometries as well as custom designs based on drawings or samples. For applications requiring continuous operation, coated or surface-treated variants are available to reduce adhesion and facilitate cleaning. All parameters are precisely tailored to your production and process requirements.

Applications
The function of electrodes in spot welding
Spot welding electrodes direct current and force precisely into the joining zone. They ensure electrical contact with the workpiece and concentrate current flow at the weld spot. During the current pulse, electrical resistance at the contact interface generates heat, locally melting the material. At the same time, the electrode transfers the force needed to form the weld nugget.
Quality-relevant features of electrodes
The geometry of the electrode must be precisely manufactured to ensure that the current and contact force are evenly distributed throughout the joining zone. Even small dimensional deviations affect the force transmission and lead to weld misalignment.
The electrode alloy must combine high electrical conductivity with thermal stability. Only a balanced combination of both properties can the heat input be precisely controlled and the risk of local overheating avoided.
Electrodes are exposed to mechanical stress during operation. A hardened or coated surface protects against abrasion, reduces adhesion, and ensures constant current transfer even during high-frequency welding.
Standardized caps with a consistent mounting geometry are crucial for short changeover times. Dimensional consistency avoids adjustments during series production and reduces downtime.
