Micro Welding Electrodes

Precision-engineered electrodes for micro resistance welding applications. Deliver ultra-precise joining for electronics, medical devices, and miniature component assembly.

Precision at the Micro Scale

Micro welding demands electrodes that can deliver precise current to extremely small areas while maintaining consistent contact geometry. Our micro welding electrodes are manufactured using advanced precision machining techniques to achieve the tight tolerances and surface finishes required for demanding micro-joining applications.

From battery cell tab welding to medical device assembly, these electrodes enable reliable joining of miniature components where conventional welding electrodes cannot provide the required precision. The exceptional surface finish prevents sticking and ensures clean weld surfaces critical for sensitive applications.

Available in a range of high-purity materials selected for specific application requirements, our micro welding electrodes support both manual precision welding and high-speed automated production systems.
