Effect of Welding Parameters and Electrodes on Bead width using Gas Metal ARC Welding

Abstract

In this research work, an attempt has been made to formulate and investigate the effect of GMAW conditions on bead width during the cladding of low carbon steel pale using AISI 308H electrodes. The Box- Behnken design has been employed for the development of mathematical relationship. The voltage, current and wire diameter have been considered as cladding conditions. The variation of bead width with voltage and current have been found non linear while, the effect of wire diameter on bead width has been observed linear. On the other hand, the bead width continuously increases with increase in voltage, current and wire diameter.
