Electric resistance welding needle polishing and cleaning device

Technical Field

In the production process of the cylindrical sodium ion battery, two lugs (made of aluminum-nickel composite belt materials) on the negative electrode are connected with the bottom of the nickel-plated steel shell through welding, so that current conduction is realized. The quality of the welding effect of the bottom shell determines whether the battery can be charged and discharged normally, and influences the service life, quality and production efficiency of the battery. Resistance welding is a relatively common bottom shell welding mode in the industry at present. It is a manufacturing process and technique for joining metals or other thermoplastic materials by heating. The specific process is that after the workpieces are combined and positioned, the workpieces are tightly contacted by applying pressure through an electrode, and the two types of workpieces are fused and welded by utilizing resistance heat generated by current passing through the contact surface and the adjacent area of the joint.

The cylindrical sodium ion battery negative electrode lug adopts an aluminum-nickel composite belt, and the welding is nickel-aluminum-nickel from top to bottom, and the aluminum material temperature is easy to be overhigh during nickel welding due to the difference of the melting points of the two materials (nickel is far higher than aluminum).
