Electric resistance welding ( ERW) is a welding process where metal parts in contact are permanently joined by heating them with an electric current, melting the metal at the joint. Define electric resistance welding. Simultaneously, the weld is made by a mix of time, pressing factors, and warmth. Electric resistance welding is widely used, for example, in manufacture of steel pipe and in assembly of bodies for automobiles. The weld is made by conducting a strong current through the metal combination to heat up and finally melt the metals at localized point(s) predetermined by the design of the electrodes and/or the workpieces to be welded. Electric resistance welding is widely used, for example, in manufacture of steel pipe and in assembly of bodies for automobiles. Ranking Electric resistance welding equipment, non-automatic ranks 460th in the Product Complexity Index (PCI). electric resistance welding synonyms, electric resistance welding pronunciation, electric resistance welding translation, English dictionary definition of electric resistance welding. Resistance welding is the joining of metals by applying pressure and passing current for a length of time through the joined metal area. Electric Resistance welding • Type of pressure welding used for joining pieces of sheet metal or wire. It describes the differences among the processes, as well as the power supplies and weld rolls. How is electrical resistance measured? . [2] (a) under-cutting of a base material. (b) burn through. Many reports on the ERW have been presented up to date; most have been concerned with the design of a welding device or production Electrical resistance welded tubes are produced from a hot rolled scale-free strip which is formed by rolls at room temperature into a tubular shape. There are many different types of resistance welding. During ERW, a high frequency electrical current is transmitted to the material by means of copper sliding contacts so that the abutting edges initiate fusion. About Electrical Resistance Welding. Electrical resistance welding (ERW) is a form of pressure welding which utilizes heat generated by electrical resistance of the material along with applied force to hold the pieces together during the welding process. Resistance welding embraces the branch of welding art in which the welding heat is generated by the resistance of the parts being welded and the passage of an electric current. Description Resistance welding equipment is used to weld metals that have to be welded without heat. Electric resistance welded (ERW) pipe is made from steel coil and the weld seam runs parallel to the pipe. 6.
