● Suitable for spot welding between materials such as nickel strip, nickel infiltrated steel sheet, and coated steel strip in battery production. In the production of nickel gas batteries, nickel pot batteries, polymer batteries, lithium batteries, and other batteries, spot welding of connecting pieces, cells, and lead-out pieces is necessary.
● Material: Domestic material, Taiwanese material, Japanese material, American material
● Needle models: eccentric flat head, eccentric ball head, same core ball head, straight baseball head, straight rod, other customized
● All welding needles produced by our manufacturer are made of aluminum oxide copper material
● Electric resistance welding material - nano alumina dispersion strengthened copper (alumina copper)
● Aluminum oxide copper - specially designed for spot welding of galvanized steel plates, nickel plated plates, nickel strips, aluminum alloys, stainless steel, brass, and other materials
● Aluminum oxide copper material is resistant to softening and erosion, with a long service life and high spot welding frequency. The electrode life is more than 5 times that of ordinary chromium zirconium copper, reducing the time for stopping work and grinding the electrode
