The purpose of this project is to conduct a comparative literature study of different welding techniques for welding batteries. The compared techniques are resistance spot welding, laser beam welding and ultrasonic welding. The performance was evaluated in terms of numerous factors such as production cost, degree of automation and weld quality.
The search was then performed using Uppsala University’s Library database and Google scholar which cover a wide range of articles and sources. Three methods for welding batteries were given in the template, being laser beam-, ultrasonic-, and resistance spot welding.
UWB is also suitable for creating electrical connections between cylindrical battery cells. Although proper fixation of the cell is paramount for the welding, as any significant lateral movement will reduce the vibration amplitude and consequently diminish the power of the welding process.
4.1.2 Effect on the battery cell Small-scale resistance welding is often the preferred method for joining Li–ion batteries into battery packs. This process ensures strong joints with an almost complete elimination of the heat impact on the joined workpieces during a short time.
Battery cells are most often put into modules or packs when produced for electrically driven vehicles. The variable of greatest influence when welding battery packs is the contact resistance between the cell and the connection tab. It is crucial to minimize this variable as much as possible to prevent energy loss in the form of heat generation.
Parameter control also allows LBW to adapt to the thickness of the material tabs and can create thin or thick weld nuggets. In battery cell welding it is important to create thin welds due to the relatively thin battery cases and the risk of the weld penetrating the case and thus damaging the core.
Battery Pack Laser Welding System
To meet this growing demand, SIL has developed the Lithium Ion Battery Laser Welding Machine. This innovative machine enables precise welding of prismatic cells made from materials such as aluminum, aluminum alloy, stainless steel, or OFHC Copper. It is capable of welding components with a thickness ranging from 0.5 mm to 3 mm.

Laser Welding on EV Battery and Automation
There are 2 methods for Laser Welding: 1. Tactile Welding This method uses a filler wire which also acts as tactile sensor. The wire is constantly under control and in touch with the seam, which acts as a sensor and senses the seam profile. Welding is done accordingly. The filler wire can also be used to bridge the gaps.
