External magnetic field (EMF) nowadays is widely used in application of arc welding because of its positive effects on weld quality and weld geometry. The presence of EMF during arc welding lowers the value of sensitization of metal near the heated area resulting in resistance to localized corrosion. This resistance to corrosion is caused mainly due to Cr redistribution in base metal due to externally applied magnetic field. The applied EMF deflects the welding arc by electromagnetic force and applies force on electrons and ions within the arc which causes arc to deflect away from the normal path. Further, the welding arc can be made to deflect backward, forward or sideways with reference to welding direction and electrode depending upon the direction of applied magnetic field. In this article, results of various different experiments performed by taking different welding parameters are studied which would contribute in improvement of weld quality as well as weld geometry.
