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.

Is micro-Tig good for battery pack welding?

Micro-TIG is best suited for tab-to-busbar welding for low to high capacity packs. For more information read Battery Welding Solutions Using Laser & Resistance Technologies. Battery pack welding. The right technology for your job depends on factors including materials, part accessibility, throughput, and budget.

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.

Can laser welding be used for pouch cells?

However, laser welding technology can be used for pouch cells if the foils are in close contact and a pulsed laser is used to avoid overheating. In the case of pouch cell case sealing, typically a compact heat sealer is used to seal aluminium-polymer laminate films.

Which welding technology is best for a high quality volume production?

Resistance spot welding, micro TIG welding, and laser welding processes all enable high quality volume production. The selection of one technology over another is usually made based on the application’s specific requirements and the alignment of the technology to these needs.

What is laser beam welding?

Laser beam welding is used to join similar or different materials without the need for filler material, for example aluminium to aluminium for sealing prismatic cells or copper to aluminium to connect the tabs of the cells to the pack’s terminal. Additional filler material can be useful when building battery frames.
