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.
Friction stir welding is generally a welding technology with a low heat generation compared to fusion joining, whereas it was not investigated whether or not the frictional heat may damage battery cells. In the case of cylindrical cells, it remains open whether or not welding might thermally or physically damage the cells.
Grimm et al. (Grimm et al., 2015) stated friction stir welding as an alternative process for automotive batteries due to the capability of joining dissimilar materials, like aluminium and copper for instance, without the formation of undesired intermetallic compounds.
Additionally, the three welding techniques are compared quantitatively in terms of ultimate tensile strength, heat input into a battery cell caused by the welding process, and electrical contact resistance.
The findings are applicable to all kinds of battery cell casings. Additionally, the three welding techniques are compared quantitatively in terms of ultimate tensile strength, heat input into a battery cell caused by the welding process, and electrical contact resistance.
Laser brazing of aluminium and copper where the aluminium melts and the copper remains in sold state during the brazing process (Solchenbach et al., 2014). As an industrially commonly used joining technique laser welding can be employed for interconnecting batteries. Fig. 9 (a) shows different weld seams which are produced by laser beam welding.
