Abstract
Gas tungsten arc (GTA) welding process is the best choice for joining Ti–6Al–4V (grade 5) material, with economical cost. To support the above aim, two simulation works are studied in this research. First work focuses on the simulation of GTA welding process. The second work focuses on the simulation of the tensile and cupping test. Initially, GTA welding parameters such as welding current (115–135 A) and welding speed (250–450 mm/min) are taken for conducting bead on plate (BoP) trials. From these BoP trails, bead profiles are measured to build a moving heat source model in COMSOL. The arc efficiency (η) is focused on this welding simulation. Using Abaqus software, tensile and cupping test analysis is performed to predict the fracture location and elongation. The bead profile at arc efficiency of 60% showed a better match with the experimental work. By implementing the temperature distribution analysis, the bright silver colour bead is achieved in experimental work. The butt joint showed comparable strength (95.9%) to the base metal; also the simulation error is not exceeded by 10%. The crack location predicted from the numerical study highly coincides with the experimental work for the cupping test.
