Optimization of Flux Composition for Enhanced Penetration Depth in F-GTAW Processes Using the Taguchi Method

Abstract

The Taguchi technique is used to investigate how oxide fluxes effect arc constriction, current density, and weld depth. Researchers can improve TIG welding efficiency, pass count, and weld quality for precise applications by optimising flux formulations. The optimal parameter combinations for penetration depth & structural integrity assist TIG welding overcome its drawbacks, such as limited productivity and material composition sensitivity. Tungsten Inert Gas or TIG welding optimisation relies on the Taguchi approach, especially when studying multi-component fluxes' impacts on weld properties. Weld penetration impacts TIG welding joint quality and integrity, affecting depth-to-width ratio, which dictates pass count. To evaluate the impact of flux composition on weld penetration, morphology, along with δ-ferrite content in 6mm solid AISI 316L austenitic stainless-steel plates, the Taguchi method can be used to create an experimental design. The Taguchi method lets you thoroughly study control factors like flux makeup, current, and welding speed. The goal is to find the best conditions for improving weld quality and penetration. Because orthogonal groups are used, the method makes sure that only a few experiments are needed to see how these factors affect each other. Signal-to-Noise (S/N) ratio research can also be used to find the best choices for a process that will always produce high-quality results with little variation.
