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.
The TIG battery welding process has been tested and proven with a number of battery pack designs using nickel, aluminium and copper flat. The high degree of control offered by the power source enables the resultant spotwelds to be optimised to size while minimising heat penetration into the battery can.
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.
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.
Thus the welding method has a minimal impact on the battery as there are no catalyzing reactions in the battery caused by the heat. On the other hand deformation may occur if too great of a welding force is applied by the electrodes. This deformation may alter the temperature distribution and hinder the current from flowing the shortest path.
Hence, the weld would not cause any significant resistance heating of the battery during charge or discharge . 4.3.2 Effect on the battery cell High currents must flow through the welds between battery cells in order to deliver the electricity needed to power a battery electric vehicle. These welds are the bottleneck of the electric circuit.

The battery tray enclosure (BTE) is an important part of new energy vehicles, and has high requirements on quality, strength and heat dissipation.
The welding output voltage of our homemade welder is 38 volts. Our input is 220V AC from the wall outlet. Many experts prefer a 220V welder instead of 110V due to the good duty cycle. Another reason is the excellent built quality of transformers to handle 50 Hz electricity. So I advise people to make 220V welder even if they have a 110V wall

• When electric welding is carried out on the vehicle, or repair work is made on the heater, the heater must be disconnected from the battery. • Do not use fuses rated differently from indicated on the electric circuit diagram. • Do not use makeshift devices (wires etc.) instead of fuses.
An inverter welding machine is a type of welding machine that uses an inverter to convert AC power from the mains supply to DC power for the welding arc. This type of welding machine is more efficient than traditional transformer-based welding machines, and it produces a smoother arc, which results in better weld quality.
