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.
Fusion welding, specifically using electron beams or lasers, is the best method for welding battery components. Both electron beam and laser welding offer high power densities, pinpoint accuracy, and are well-suited for automated welding processes and small, miniature weld applications.
Depending on the project parameters, both laser welding and electron beam welding can be cost effective for battery arrays. However, battery array configurations are becoming more compact, and designs are continually evolving.
Battery Laser Welding Machine is a precision tool developed for the use in joining and welding metallic components of batteries including tabs, terminals, and cases. One key reason that battery laser welding machine is used is because of accuracy, speed, and most importantly, the quality of welds necessary for battery manufacturing.
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.
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.

In this work, the process of keyhole welding was used to connect battery cells. The functional principle is shown in the illustration in Fig. 12 (a). The laser beam reaches high power densities I > 10 12 W/m 2, which melt and evaporate the metals. The vapor causes a recoil pressure that opens a capillary [27].
