Optimizing Mechanical Properties UT-Strength and Hardness Through Submerged Arc Welding of A24 SS316 Alloy

Abstract

The study utilized the Taguchi technique to optimize the process parameters of submerged arc welding (SAW) with a focus on enhancing mechanical properties like Ultimate Tensile Strength (UTS) and hardness. Several weld quality factors were taken into account, and a thorough description of the process and outcomes using the Taguchi method was provided. This approach, known for its statistical analysis efficiency requiring minimal trials, was applied to Material A24 SS316 using an L9 orthogonal array across various current, voltage, and speed settings. By comparing expected and actual values with regression analysis-ANOVA, with and without interactions, the study successfully attained the desired outcomes. A validation experiment further confirmed the reliability of the Taguchi technique in predicting UTS and hardness performance. Consequently, the research offers valuable insights for optimizing SAW process parameters to enhance mechanical properties while showcasing the effectiveness of the Taguchi method in predicting and achieving optimal welding results.
