6 FAQs about [New energy battery soft copper wire welding]

What is TIG battery welding?

This therefore provides a highly controlled method of developing localised welding temperatures that are suitable for joining materials up to 0.5 mm thick onto conductive battery cans. The TIG battery welding process has been tested and proven with a number of battery pack designs using nickel, aluminium and copper flat.

Why do we infer a fracture in copper foil & not a weld?

When the tooling is aligned, the fracture is observed only in the copper foil and not in the weld. Therefore, we infer that the fracture is in the copper foil and not the weld, because the strength of the weld is greater than that of the copper foil.

Can ultrasonic energy be used for metal welding?

It produces wide welds in a short period of time. And, there is minimal formation of intermetallic compounds and minimal energy loss at the contact part. Numerous studies have examined the use of ultrasonic energy for metal welding for EV components. Most have focused on single tab-to-tab or tab-to-bus-bar welding.

Is ultrasonic welding a viable alternative to resistance welding & laser welding?

How is a battery interconnection made?

Spot-welding strips and tabs onto batteries in order to make battery interconnections and larger battery pack assemblies is a common production technique. Typically, battery interconnections are made from nickel strips, often designed with splits and projections that are then resistance-welded using parallel gap or step welding methods.

What is micro-Tig arc welding?

The more stable arc from micro-TIG systems allows for finer pulsed arc welding for copper-to-copper joining. In pouch cells, the internal electrode stack is contained within a soft plasticaluminium laminate package. Current collectors are welded internally to terminal tabs that protrude through seals to allow external connection.
