Products Description
The Silver and Copper Welding Button Contact is a core connection component designed specifically for medium and low voltage electrical equipment, widely used in circuit breakers, contactors, relays, and various power switching devices. This product utilizes advanced silver-based brazing technology to establish a high-strength, low-resistance metallurgical bond between the silver contacts and the copper current-carrying terminals, ensuring long-term reliability under frequent switching and high-current loads.
Production Process
Raw Material Incoming Inspection
Each batch of silver/silver-based alloy raw materials and copper terminal raw materials undergoes spectral analysis to accurately verify the composition and ensure that the silver purity, alloy ratio, and copper purity meet design requirements. Impure or contaminated Resistive Welding Silver Contact materials are discarded, controlling quality from the source.
Precision Machining of Contacts and Terminals
High-precision machining equipment is used to stamp and grind the silver/silver-based alloy to produce button-type contacts, with dimensional tolerances controlled within ±0.01mm. Copper terminals undergo precision turning and stamping to ensure a smooth, burr-free surface, suitable for brazing processes.
Pre-treatment Process
The welding surfaces of the Electric Resistance Spot Welding Silver Contact undergo degreasing, pickling, and grinding to remove surface oil and oxide layers, ensuring a clean welding surface, improving the bonding strength of the silver brazing, and preventing incomplete or missed welds caused by surface impurities.
Core Processing for Silver Brazing
Utilizing silver-based filler metal brazing technology for AC Resistance Welding Silver Contact, the silver contacts and copper terminals are precisely positioned and placed into high-precision brazing equipment. Three key parameters are strictly controlled: the melting point of the brazing filler metal (adapted to the material, typically 600℃~800℃), the heating temperature, and the holding time.
