| Abstract: | Spot welding is a common method used for assembling battery packs. Unlike soldering, which places large amounts of heat stress on the battery, spot welding uses a short burst of large current which melts the metals at a desired point and creates a strong bond upon cooling. The goal for this tab welder is to utilize the process of capacitive discharge to achieve the welding of nickel tabs to 18650 and 26650 Lithium-Ion batteries as well as be able to create a junction between two dissimilar metals for homemade thermocouples. |
