Numerical and Experimental Investigation of the Effect of Overlapping Angle on Strength and Deformation of Curved Plate Joined Using Arc Welding Process

This research presents a comprehensive numerical and experimental investigation into the influence of overlapping angles from 30° to 100° with a 5° increment on the mechanical strength and deformation behaviour of curved plates joined using the arc welding process. This study employs Finite Element Analysis (FEA) to simulate the welding process and assess the stress distribution and deformation across the welded joint. The simulations complemented by experimental trials; wherein curved plates joined at varying overlapping angles using arc welding. Mechanical tests, including tensile and bending tests, conducted to evaluate the joint strength and deformation characteristics. The results reveal a significant impact of the overlapping angle on the welded joint's performance. Specifically, an optimal overlapping angle identified, which maximizes joint strength while minimizing deformation. The findings contribute to a better understanding of the welding process for curved plates and offer practical guidelines for optimizing welded joint design in engineering applications.
