Spot Welding Needles Application:
1. In the battery industry: battery caps, battery nickel sheets, battery lugs, battery lead-out sheets, button battery welding. Used for welding of various batteries (nickel-metal hydride, nickel-cadmium, lithium batteries) electrode plates, negative pins, and bus bars.
2. In the automobile and motorcycle accessories and hardware industries: suitable for various terminal and wiring harness welding, enameled wire welding, terminal and copper sheet welding, nickel sheet welding, automobile connecting wire and other precision wiring harness welding, micro-motor motor lead welding.
3. In the electronics and electrical components industry: silver contacts on various switches, between lead wires and spray gold surfaces, between electronic pins, between flexible wires and flexible wires, copper wires and resistor pins, capacitor pins, LEDs Welding of lamp pins, socket insert pins, plugs and other electronic pins.
The main advantages of spot welding needles:
1. Avoid sticking electrodes.
2. The welding part is not yellow, and the welding spot is beautiful.
3. Avoid the phenomenon of virtual welding.
4. Put an end to welding sparks.
5. Excellent electrical conductivity and thermal conductivity.
6. Good high temperature performance.
7. Meet the requirements of SGS environmental protection standards and MSDS standards
