Abstract
Welding is one of the most popular methods of metal joining processes. The joining of the materials by welding provides a permanent joint of the components. The objective of this research is to determine the influence of various welding parameters on the weld bead of SS 304 welded joint. Welding technique of Gas Tungsten Arc Welding (GTAW) was involved in this research work and the influence of the welding speed, current, electrode, root gap on the strength of the material was analysed. The result showed that speed is most influencing factor to have highest bend strength and current that is to be used while welding is the most influencing factor to get higher tensile strength. Taguchi method is a powerful tool that uses a special design to study the parameter space with small number of experiments through orthogonal arrays. In a Taguchi grey relational analysis, it has been found that the optimal results occur when the cutting speed is 1.7mm/ sec, the current is 80 Ampere, and the electrode size is 1.6mm.
