Advantages of Brazed Silver Contact

Weld cracks
High-purity silver provides excellent electrical/thermal conductivity and reduces sulfide formation, effectively lowering the risk of weld cracks.

Porosity
Strict cleaning plus 99.99% silver or agsno/agsno₂/agcdo alloys ensure a clean welding surface and greatly reduce pore formation.

Incomplete penetration

Precise control of current, voltage, and speed in brazed silver contacts ensures full penetration. Automated welding provides high efficiency and stable quality.

Poor weld formation

Optimized welding parameters give silver button contacts a smooth, strong, and consistent weld—ideal for switches, relays, and mccbs.

Undercut

Accurate current and speed control prevent undercut, keeping the weld neat and structurally reliable.

Slag & spatter

Composite weld contacts use stable parameters and quality shielding gas to reduce slag and spatter, improving overall weld cleanliness.
