Abstract: Spot welding is a sort of electric resistance welding that is used to unite contacting metal surface points on various sheet metal goods. This is accomplished by a process in which heat is produced through resistance to electric current. It works by contacting copper alloy electrodes to the sheet surfaces, where the pressure and electric current are applied and heat is generated by the passage of current through resistive materials such as low-carbon steels. Using shaped alloy copper electrodes that conduct an electrical current through the weld pieces, the procedure entails applying pressure and heat to the weld region. The component melts, joining the pieces together. Portable is a term that describes "capable of being carried from place to place". This mini project is designed in such a way that the spot welding machine should be light in weight and convenient to carry. In the present work, we have tried to overcome the above problems by restructuring the design. The newly designed apparatus was a simpler, lighter, portable, compact, and flexible machine which will be able to weld at any angle and can be easily operated by even a non-skilled Labor with much ease and required accuracy.
