Abstract—Finite Element Analysis (FEA) has become a practical method of predicting stresses and deflection for loaded structures. FEA identifies the load path, which can be difficult using classical analysis with complex structures. Welding enables direct transfer of stress between members, eliminating gusset and splice plates necessary for bolted structures. In this paper single transverse fillet weld and double transverse fillet weld are used for analysis. Weld joints form an important part of pressure vessels, they are highly essential for structural integrity of the system. Typical welds are done on flat surfaces and their strengths are well catalogued for reference. The objective of this research project is to analyze welds on curved plated and determine their strength, and create a similar catalogue for curved surfaces of certain cases.

Index Terms—Finite element analysis, Double transverse weld, Single transverse weld, Curved plate.
