Abstract

This study investigates the thermal behaviour during welding of oil pipeline steels using finite element analysis (FEA), design of experiments (DOE), and advanced modelling tools. Employing Autodesk Inventor for three-dimensional modelling and Autodesk CFD for thermal analysis, the research examines the influence of critical parameters, including material thickness, number of weld passes, and welding current, on heat distribution, heat-affected zones (HAZ), and weld quality. Parameters were systematically varied following a Taguchi L9 orthogonal array, with welding conditions such as electrode type (E6013), voltage (24 V), and specific geometric configurations. Results indicate that material thickness significantly impacts heat flow and thermal gradients, with thicker steels exhibiting larger HAZ sizes. The integration of advanced computational models highlights the importance of optimising welding parameters to mitigate defects such as residual stresses and microstructural anomalies. These findings provide practical guidelines for enhancing weld integrity and pipeline lifespan under operational stresses.
