EFFECT ON TOOL ROTATION SPEED AND DWELL TIME ON MECHANICAL PROPERTIES OF FRICTION MELT BONDED SPOT WELDING OF ALUMINUM WELDED WITH ALUMINIUM FOIL LAYER

Mechanical Engineering

The fabrication tab requires a joining process in the battery, which is an essential storage device in renewable energy sectors. The joining process of a battery pack with a pouch cell configuration consists of three levels: cell, module, and pack. The joining of thin aluminium (Al) is essential for the battery production. Al is characterized as high thermally and electrically conductive materials. However, obtaining a quality Al weld using conventional methods is hard and the durability of weldments is uncertain. In order to overcome the aforementioned difficulties, friction melt bonding (FMB) is a liquid state technique used in this work for joining of aluminium alloys. FMB takes the advantage of large differences in the melting temperature of the materials to be joined and promises good weld quality. A different combination of rotational speed and dwell time is used for joining. The findings showed that the tensile shear-fracture load (TSFL) was significantly influenced by the tool's rotational speed and dwell time. The best combination of process parameters for better TSFL is identified and reported here.
