Resistance welding uses electrical current to provide energy to melt and join two parts together: electrodes provide a mechanical force to bring and hold them in contact. The resistance between the materials and in the bulk induce heat that eventually exceeds the melting points, allowing the bond to form.
For resistance welding, processing speed is limited by the motion necessary to move the pack under the electrodes, and the electrode actuation to weld the different cells. After welding, motion is again necessary to move from cell to cell. The time needed to raise and lower the electrode to the weld location can be estimated at 1 second.
It is not possible to join this type of geometry with resistance welding, but is possible with a laser since its focal spot can be on the order of 25-50 microns. Because the edge of the cell is rolled, there is only a narrow width where the tab makes good contact with the terminal.
Although it would seem that there is ample room to place a weld on the battery cells in a pack, the required precision of the placement is very high depending on the cell design. When the positive and negative terminals are on opposite sides of the battery, resistance welding is a viable joining technology.
Motion between fields at 1ips. For battery packs, the tolerance of the working distance generally needs to be <+/- 0.5 mm, but in some cases, can be as small as <±0.25 mm. This value depends on the tab material and the laser type. To achieve this, a pre-check is often employed prior to welding to ensure that the working distance is maintained.
Both resistance and laser welding are capable of semi-automated or fully automated processing, but there are fundamental limits in the processing speed. For resistance welding, processing speed is limited by the motion necessary to move the pack under the electrodes, and the electrode actuation to weld the different cells.
