The main characteristic of resistance spot welding is that only a small volume of the work pieces is melted and fused together. The welding heat is generated by the electrical power.

Ultrasonic welding is a solid-state welding technique. The work pieces are not melted but pressed and scrubbed together [11], [12], [13]. Fig. 8 illustrates the functional principle of weldi.

Laser beam welding uses the absorption of electromagnetic waves to heat up the joint partners. The laser beam can be provided by various laser sources [25]. In this study, the laser source.Resistance spot, ultrasonic or laser beam welding are mostly used for connecting battery cells in the production of large battery assemblies. Each of these welding techniques has its own characteristics depending on the material properties and contact geometry. Cell casing and terminal dimensions may constrain possible contact geometries.
