Purpose: Welding is one of the important processes for the manufacture of a wide variety of products. Most of the manufactured products have to be produced by welding due to its greater productivity and economical viability. Still quality has to be enhanced in the products. To attain the perfect quality in weld a new attempt has been tried out while existing process are being optimized. In this direction, the conventional Gas Metal Arc Welding (GMAW) has been developed to encourage high welding performance variant. Influence of changing filler metal geometry is one of the ways to improve the capability of giving high deposition rate and penetration. Accordingly, a flat wire arc welding system has been developed and weld bead characteristic has been investigated. The overall results show that, the proposed technique of changing wire electrode geometry can be used effectively to improve the weld bead characteristics. In this article, how does a change in electrode geometry contribute to the weld quality in manufacturing industries, is well- verified by experimental results, which are also explored here.
