OPTIMIZATION OF WELDING PARAMETERS FOR MIG WELDING OF AL 6061-T6 USING TAGUCHI TECHNIQUE

In present work Metal inert gas welding weld beads are produced of 6mm thick of material Al 6061-T6 aluminum alloy using Taguchi technique as design of experiments for conducting experiments, and influence of MIG welding parameters on weld bead geometries is investigated. The process parameters of welding considered are angle of the gun, Feed rate of electrode wire, Standoff distance, Welding speed and Current. Optimization of welding parameters was obtained by identifying most influencing parameters using S/N ratio analysis.
