Spot Welding Needle 3.0*100*2.0MM Battery Pack Welding Special
Welding Needle
Product introduction
● 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.
● Product name: Aluminum oxide copper spot welding needle, butt
welding needle
● 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
● The battery spot welding machine adopts aluminum oxide copper
material welding needles, which improves the efficiency of
automatic welding production lines. When welding coated metal, the
electrodes are not bonded, providing a terminal solution for the
welding of galvanized steel plates. It is an indispensable
electrode material for welding galvanized steel plates, nickel
plates, nickel strips, aluminum alloys, stainless steel, brass, and
other essential electrode materials.
● The softening temperature of aluminum oxide copper welding needle
can reach 930 ℃, making it a relatively high alloy in copper. The
conductivity can reach 85% IACS, with high strength and good wear
resistance.
● The conductivity can reach 85% IACS, and the heat dissipation
performance is between tungsten copper (220 W/m.k) and pure copper
(390 W/m-k).
● The softening temperature can reach 930 ℃, which is relatively
high among copper alloys, but lower than tungsten copper (1000 ℃)
Features
