abstract

The objective of the current work is to provide sufficient knowledge of the welding industry to allow the optimization of the process so as to achieve best final properties. The welding process is complex with many interacting variables controlling the procedure. In addition, not all of the physics of the process, particularly with regard to the factors which control mechanical properties, are well understood. It is unlikely that a full analytical model can be prepared and physically based numerical techniques will also suffer from a lack of basic understanding. A model for use as an optimization tool will thus have to proceed along different lines. Fortunately, this work has produced a wealth of experimental observations, which can be used for optimization. In this research, several welds were fabricated using Gas Metal Arc Welding process at different welding conditions. The technique of Response Surface Methodology was applied to develop a mathematical model to analyze various effects of GMAW parameters on the and mechanical properties such as yield strength and ultimate tensile strength of Duplex Stainless Steel weldments.
