Resistance Welding: Resistance welding is a process in which two or more parts are welded by the coordinated and regulated use of heat and pressure. The heat in the resistance welding process is generated by the resistance offered by the workpieces to the flow of low voltage high-density electric current. The pressure for welding is applied through the contacting electrodes. It may be obtained by mechanical means, springs, air pressure, or hydraulically with the help of a pressure cylinder and piston arrangement. The pressure generally used ranges from 30 to 55 MPa. The high-density current is produced by using a
