Abstract: 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. If a lap joint is required for longitudinal plates, the reference for taking overlap length is available. When a lap joint is required for curved plates, no reference is available for it. The objective of the project is to form certain set of guidelines or set of formulations which will serve as a guideline for overlap length in lap joint of curve plates. Analysis type for this will be Structural Non Linear Finite Element Analysis i.e. by using ANSYS 12.0 Workbench for modeling and ANSYS 12.0 for Structural Non Linear Analysis. No of Estimated Analysis conducted is 53 for three different cases of analysis. We have studied by analysis and experimentation of 03 cases, for which we required to conduct 53 analyses. After this analysis, experimentation results and their comparison we have to make the conclusion or forming certain set formulations which will serve as a guideline for welds of curve plates with an overlap.
