Products Description
In the field of low- and medium-voltage electrical appliances such as circuit breakers, contactors, and industrial switches, the reliability of electrical connections directly determines the safety level and service life of the system. Resistance Butt Welding Silver Contact represents a high-end solution for electrical contact material connection technology.
For electrical engineers and purchasing experts, this component not only solves the high impedance problem of dissimilar metal connections but also achieves efficient transmission of high current and excellent arc resistance within a very small space. It is a key component ensuring the stable operation of the power system under extreme conditions such as short circuits and overloads.
Technical Features
"Quasi-isostatic pressing" weld interface formation
Under upsetting pressure, the metals of Electric Resistance Welding Silver Contact in a high-temperature plastic state at the interface undergo diffusion and recrystallization under triaxial compressive stress, forming a dense, non-porous bonding zone with fine grains and excellent performance.
Extremely small and controllable heat-affected zone (HAZ)
Welding heat is highly concentrated at the Projection Welding Silver Contact interface. By precisely controlling the heat input and rapid cooling after upsetting, the HAZ between the silver contact and the copper substrate can be controlled within an extremely narrow range, maximizing the preservation of the base material's properties.
Suitable for dissimilar metals and complex cross-sections
The process is particularly suitable for joining dissimilar materials such as silver and copper, and copper alloys. Through electrode and process design, reliable welding of irregular cross-section contacts (such as rectangular and trapezoidal shapes) can be achieved for Resistance Spot Welding Silver Contact.
Detailed Display
Weld Interface Microstructure: Shows the gradient structure formed by the interdiffusion of silver and copper in the bonding zone, free of defects such as cracks, porosity, and lack of bonding. Common recrystallized grains are visible across the interface for Projection Welding Silver Contact.
Weld Flash Morphology: Shows uniform and continuous flash, a sign that ductile metal has been successfully extruded during welding, indirectly reflecting weld quality for Electric Resistance Welding Silver Contact.
Tensile/Shear Test Fracture Surface: Shows that the fracture location is usually in the silver or copper base material, rather than the weld interface, proving that the interface strength is higher than that of the base material for Resistance Seam Welding Silver Contact.
Product Processing and Customization Process
Requirements Submission and Evaluation
The customer provides drawings in PDF/CAD/3D formats, clearly specifying core requirements such as Copper Spot Welding Silver Contact dimensions, silver contact thickness, welding processes, and power compatibility. Our company simultaneously conducts process feasibility analysis and accurate price evaluation, and quickly provides feedback to the customer on the evaluation results.
Mold Production and Sample Testing
After price confirmation, the customer places a sample order and prepays 50% of the mold fee. Our company immediately starts mold production. After mold production is completed, 1-20 Resistive Welding Silver Contact samples are provided free of charge and sent to the customer for testing and verification.
Mass Production and Delivery
After the sample passes customer testing, the customer pays the remaining 50% of the mold fee and simultaneously places a mass order with a 30% prepayment. After assessing the delivery date, our company starts mass production. After AC Resistance Welding Silver Contact production is completed, we provide the customer with a packing list. Once the customer pays the remaining 70% of the payment, our company will deliver the goods according to the customer's specified method.
