Abstract
The metal inert gas (MIG) welding technique is the most commonly used welding technology in the industry. Welding distortion in manufactured goods or parts is one of the main problems in the manufacturing industries since correcting the distortion would be more expensive and time-consuming. A deviation from the desired or initial shape and size is referred to as distortion. This research looks at several welding parameters for Metal Inert Gas (MIG) welding and the effect to the welding distortion in both simulation and experimental work and determining the best welding parameters that promotes the least amount of distortion. With welding settings are identical in both simulation and experimental works. ANSYS software is used to construct a three-dimensional and two step transient thermo mechanical finite element model research to examine and assess the distortion behavior. The experiment will be analyzed using Design of Experiment (DOE) approaches, which will include both a computational and physical experimental approach. In order to establish the optimal parameter for minimizing distortion in mild steel welded joints, the results of both computational and physical testing methodologies will be investigated. From both the experimental and simulation analysis, both method suggest that lower voltage and wire feed rate promotes lower distortion and the simulation shows a similar trend to past research in term of voltage and wire feed rate effects on distortion. The experimental result does have a fluctuation of data due to incompetent technical equipment and methodology if compared to past research and simulation where both has more control and are done in a near perfect condition.
