Ultrasonic bonding technology is widely used in battery production to ensure the best conductivity, even when connecting different kinds of metals.

Characteristics of ultrasonic welding process (firm, reliable and economical)

Ultrasonic welding has the advantages of firm solder joint, small internal resistance, no oxidation trace, beautiful appearance and so on; there is no spark during welding, the operator is safe and at ease, there is no smoke smell, and there is no air pollution; all welding workpieces do not need pre_treatment, do not need solder, solder and other additives can be welded, economic and convenient; welding time is very short, generally in 0.01_1s seconds instantaneous welding The welding temperature does not exceed the annealing temperature, so the metallographic structure of the weldment is not changed. The welding strength is stronger than other welding methods, and the welding interface is neat and clean.

Application cases

Power battery, soft package battery, cylindrical battery, square battery cover plate, battery module, battery soft connection welding cases.
