Abstract: The present paper deals with flux consumption in twin-wire submerged arc welding. Twin-wire submerged arc welding is an important variant of conventional single wire welding. Use of twin wires results in higher deposition rate. In general, higher deposition rate is also associated with higher flux consumption. Experimental evaluation during the present investigation into flux consumption during twin-wire welding resulted in an important observation. Unequal wire diameters at lead and trail wire resulted in lesser flux consumption. The result has been attributed to the magnetic field in the surrounding the arc envelope. Mathematical formulation of distribution of magnetic field in the surrounding welding wires has been made. It has been found that the magnetic field varies with the position of the welding wire as well as the wire diameters also play important role. It has been noted that unequal wire diameters result in directional stability of the arc which in turn reduces the flux consumption. Copyright © 2009 ASM International® All rights reserved.
