Spot Welder Welding Rods for Battery
Aluminum Oxide Copper Welding Rod
Product overview:
Aluminum oxide copper welding rod is a high-quality spot welding electrode for professional battery spot welding machine. Spot welder welding rods are subject to certain welding pressure when working, and the peak current is very high, so the electrode material requirements of spot welding needle are very high, need a very high softening temperature, high electrical conductivity and high hardness, and aluminum oxide copper welding rod just has these several advantages. Therefore, it has become the mainstream spot welding electrode material for battery pack spot welding machine.

Scope of application:
Spot welder welding rods are widely used in battery production and manufacturing processes.
In the process of assembling battery packs, welding the cell-to-cell busbar to the battery cells, welding the battery tabs to the PCBA pads, such as pure nickel strips and nickel-plated steel strips, etc.
In the process of making battery cells, welding the battery tabs to the battery cases, etc.
In addition, aluminum oxide copper welding rods are also used for welding galvanized steel, nickel-plated steel, stainless steel, nickel strip, brass, aluminum alloy and other materials.
Features:
1)Low tendency to form alloy with welded parts at high temperature, stable physical properties, good anti-stick properties.
2)The spot welding needle has the advantages of high hardness, good resistance to softening, wear resistance, high number of spot welds and long service life.
3)The spot welding rod has high hardness, good resistance to deformation and abrasion, and avoids the occurrence of false welding.
4)It has superior electrical and thermal conductivity, and is a high-quality spot welding electrode material.
5)The welded parts do not yellow easily and the welded joints are beautiful.
Kindly reminder: After a period of use, the bottom of the spot welder welding rods will become rough with burrs, which will affect the welding effect and aesthetics. A small file can be used to rub the bottom flat to remove the accumulation of oxidation, enhance the beauty of the welding surface and reduce the occurrence of spot welding needle sticky situation.
