Design and Development of a Portable Spot Welding Machine for Joining Metal using HCT

Abstract

The project aims to spot weld the battery terminals without influencing the battery life. In view of accessibility of materials on neighborhood choice of different metal strips can be spot welded on the battery terminals. The high C rating of the battery builds the thickness of the metal strip to be utilized henceforth high thickness metal strip up to 0.7mm can be welded without influencing the battery life. This builds the battery existence with great contacts of metal strip is guaranteed. The current from the transformer is constrained by appropriate postpone timing of hand-off utilizing microcontroller. This decreases the super-hot spot of metal strips during welding.
