6 FAQs about [Welding crossbar energy storage welding]

Can laser beam welding be used for overlap joints of copper and aluminium?

The differing material properties like thermal conductivity as well as the formation of intermetallic phases are challenging for welding processes. This study contains the results for overlap joints of copper and aluminium using a laser beam welding process with spatial power modulation.

Can laser beam welding be used in busbar joints?

In busbar joints, the discontinuity of welds at these cracks is a concern as it may cause poor electrical contact. Laser beam welding has unique advantages of low heat input, high process speed, non-contact heat source, ease of automation etc. The joining of Al and Steel alloys in both butt and overlap configurations with a laser has been studied.

Can a busbar be welded in conduction mode?

However, busbar joints require the joining of a thin (0.25 mm) steel tab to a thicker (3 mm) Al sheet. Conduction mode welding is not feasible for this configuration as the thicker, high thermally conductive Al dissipates the heat away.

Are busbar welds brittle?

Busbar welds must have good electrical contact, mechanical strength, and thermal stability. However, it is observed in the literature that achieving mechanically stronger welds in Al to steel dissimilar welding is challenging due to the brittle nature of IMC phases formed and consequent weld failure.

What are the process parameters involved in the welding experiment?

An FLW-D30 wobble head from IPG Photonics was used for the beam delivery and wobbling. Laser power, traverse speed, beam size (d laser), focal position, wobble amplitude, wobble frequency (f), and shielding gas flow rate are the process parameters involved in the welding experiment.

Does laser microwelding improve quality of copper welds?
