Resistance Welding

Resistance welding is the process of bonding two metals without the introduction of a third metal, using an electrode. The Resistance Welding process requires heat, time and pressure for a successful bond. Pressure and current is transferred to the parts through the electrode. Heat is produced by passing current through the materials where the bond is required. The resistance of the material to the electrical current that is passing through it supplies the heat necessary to either melt the metals together or plasticize them so that the pressure of the electrode can bond them. Applications include automotive, nickel cadmium batteries, electronic components, lamps, and medical. KEYWORDS for this process: spot
