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.
Resistance welding is one of the simplest, lowest cost, surest means of metal joining. An understanding of the resistance welding process is basic to making good welds. The machines, controls and fixtures are only the tools necessary to help make the weld. The process is doing the real work. ONE MORE TIME H=I2RT, JOULE’S LAW IT WORKS! Figure 61.
Other aids to resistance welding are available in the form of weld monitors. A weld monitor can be used to track the performance of various parameters of the welding process once good weld parameters have been established. At this point, the monitor can be used to indicate variations from an established norm.
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.
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.
