This work includes an investigation of
the effect and optimization of welding parameters on the tensile
strength in the arc metal welding process. The experimental
studies were conducted under varying welding currents, wire
diameters, and heat input. The settings of welding parameters
were determined by using the Taguchi experimental design method.
The level of importance of the welding parameters on the tensile
strength is determined by using analysis of variance (ANOVA).
The optimum welding parameter combination was obtained by using
the analysis of signal-to-noise (S/N) ratio. The tensile
strength model was formulated based on Analysis of Variance
(ANOVA) using Minitab® statistical package. The experimental
results confirmed the validity of the used Taguchi method for
enhancing the welding performance and optimizing the welding
parameters in the arc metal welding process. Keywords: Arc Metal
