Precision at the Microscale:
SVS Standards for Electrodes

Micro welding electrodes are manufactured to tight tolerances to ensure targeted current transfer onto the smallest contact areas. Both geometry and surface finish are precisely tailored to the required weld nugget size and process parameters. Upon request, we offer coated or finish-machined variants to minimize buildup and extend maintenance intervals.

Available as standard version or custom-made based on your drawings or samples. Geometry, interfaces and material are precisely matched to your requirements.

Fundamentals

Function of Electrodes in Micro Welding

In micro resistance welding, the welding current flows through two electrodes directly into the joint area. The electrical resistance at the contact point generates local heat, which melts the material locally. At the same time, the electrodes apply defined force and ensure precise alignment of the joining parts. As the material solidifies, a permanent metallurgical bond is formed.

he tip geometry of the electrodes plays a key role in directing current, distributing heat and determining the strength of the connection.

Key Parameters of Micro Welding Electrodes

  • Electrical and thermal conductivity, as well as wear resistance, depend directly on the electrode alloy. Application-specific materials ensure stable current densities and reproducible weld quality throughout the service life.

  • Machined or coated surfaces reduce contact resistance and prevent buildup of welding residues. This improves current transfer, reduces maintenance effort, and ensures consistent contact performance.

  • Tightly controlled geometries enable accurate, repeatable electrode positioning. Defined contact geometries stabilize both current input and force transmission, making processes transferable across multiple systems.
