Secure fit for every welding tong: SVS standards for electrode shanks and holders
Our shanks and holders are made from highly conductive copper alloys with excellent dimensional stability. All components are manufactured with tight tolerances to ensure precise fits. Alloys with increased hardness, extended service life, or simplified cleaning are also available.
Curved, offset, and straight versions are available in various standard sizes. If required, we manufacture variants according to drawings or samples. We precisely adapt the geometry, material, and interfaces to your fixture and process conditions.

Applications
The function of electrode shanks and holders in spot welding
Shanks and holders establish the connection between the electrode and the welding tong. They conduct the welding current from the transformer to the electrode tip, transfer the contact force to the joining zone, and mechanically couple the electrode into position.
At the same time, they serve as an interface to the tong's cooling system and assist in the dissipation of process heat. They thus enable the targeted introduction of energy, which melts the workpiece material at the contact point due to resistance and creates a bond.
Quality-relevant features of electrode shanks and holders
Electrical conductivity and heat dissipation are directly affected by the alloy composition. Highly conductive copper materials with sufficient heat resistance keep the connection stable and ensure consistent welding conditions.
Manufacturing with tight tolerances ensures full-surface contact and precise electrode guidance. Even small deviations impact force application and current transfer during the process.
Dimensions and connection shapes must precisely match the collet and electrode geometry. Only with a complete fit does the fit remain stable and allow tool-free electrode changes without readjustment.
Uniform contact surfaces prevent localized contact resistance and uncontrolled heating. Clean, burr-free transitions ensure proper current flow and reduce heat-induced wear.
Additional alloys with high heat resistance and low recrystallization sensitivity can be used to maintain shape stability under load and reduce material wear in contact areas.
A well-defined defined fit at the tong interface simplifies replacement during operation. Precisely matched connector geometries prevent twisting or misalignment and ensure repeatable electrode positioning.
