A reliable 5-ton Direct Drive Friction Welder, this cost-effective machine produces welds from a minimum weld area of 50 mm2 up to a maximum weld area of 333 mm2. Utilizing the latest in friction welding technology, the SPARTAN 5 allows design engineers to cut costs by joining dissimilar metals such as aluminum and copper for battery cables.
Friction stir welding is a process in which a rotating pin is traversed along the contact surfaces between the workpieces. The frictional heat plasticizes the material, which is welded together. The FSW process is particularly suitable for joining non-ferrous metals with a low melting temperature and for mixed-material joints.

In the present study, the feasibility of refill friction stir spot welding (refill FSSW) of multilayered commercially pure Al (CP–Al) foils for battery production is assessed. The microstructure, mechanical properties of the weld are investigated, and the related industry indicators are measured. The following conclusions are drawn:
The produced welds with flat appearance, high mechanical properties, and potential to meet industry requirements imply that refill FSSW is a promising welding technique for battery production. 1. Introduction
Therefore, welding processes such as laser beam welding (LBW), resistance spot welding (RSW), and ultrasonic welding (USW) have been developed to weld multilayered Al and Cu to a conducting tab in battery pouches . However, these techniques possess attributes that still limit their widespread usage in battery production .
The findings are applicable to all kinds of battery cell casings. Additionally, the three welding techniques are compared quantitatively in terms of ultimate tensile strength, heat input into a battery cell caused by the welding process, and electrical contact resistance.
Ultrasonic welding depends on the materials' hardness and surface roughness, . This means that highly electrically conductive materials, such as copper or aluminum, can be welded, but some difficulties arise with hard materials such as steel. The needed welding power depends on the thickness of the metal sheet vibrated by the sonotrode.
