Abstract

The integrity of welded joints is dependent on the strength and load bearing capacity of the welded joint, of which this can be achieved by maximizing the process parameters that has a positive effect on the strength and minimizing those having negative effects on the weld joints. This study is carried out with a purpose of minimizing the percentage dilution considering current, voltage and gas flow rate as the input parameters on TIG mild steel weld using expert systems. The welding experiment was performed using the Central Composite Design matrix, thereafter percentage dilution responses was measured, recorded and modelled using the Response Surface Methodology (RSM). The result obtained shows that the quadratic model has adequate strength to explain the relationship between the process factors and the percentage dilution, with with a P-value < 0.05 and coefficient of determination (R2) value of 90% and a noise to signal ratio of 10.14 indicating the accuracy and reliability of the optimal solutions.
