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.
By replacing ultrasonic bonding with laser welding, battery manufacturers simplify their production process by effectively removing an extra step. Laser Technology in Assembly Lines. With the rapid growth of EVs all over the world, battery manufacturers are working hard to optimize their processes and the efficiency of their assembly lines.

Stick welding can be performed in both AC (Alternating Current) and DC (Direct Current). For most stick electrodes, the default polarity is Direct Current Electrode Positive (DCEP), meaning the current flows positively from the negative to the positive. In this setup, the current flows from the base plate into the electrode.
