Aluminum energy storage welding nails

Which welding techniques can be used for connecting battery cells?

Brass (CuZn37) test samples are used for the quantitative comparison of the welding techniques, as this metal can be processed by all three welding techniques. At the end of the presented work, the suitability of resistance spot, ultrasonic and laser beam welding for connecting battery cells is evaluated.

Is there a quality assurance approach for laser welding?

Of course, if someone looks beyond the battery welding applications many in-process quality assurance approaches are available for welding . In the case of laser welding, the in- process monitoring is mainly based on imaging, acoustic emission, and E/M signal techniques in general .

How can a quality feature of a weld be correlated?

Their common point is that they are practically investigating how the process emissions, the input parameters, or/and the variables can be correlated to a quality feature of the weld mainly using empirical or data-driven approaches [18, 19].

Can laser welding of pouch cell tabs be used in overlapping configuration?

Experimental setup & Quality Inspection As a case study, the laser welding of pouch cell tabs in an overlapping configuration is investigated.
