Alireza M. Haghighi graduated with an BSc. degree of Mechanical Engineering in Heat & Fluids in August 2016, and an MSc of Applied Mechanics in December 2019 from Bahonar University, Iran. During this period, his research focused on the effects of welding parameters, preheating and time interval on residual stress and distortion of joining ST52 T-shape stiffener ring in an AISI4130 thin-walled tubular shell. His research background is in the fields of simulating and analysing welding and additive manufacturing processes by means of numerical method and image processing of porous materials. Alireza began his PhD in June 2021 focusing on that project; his research now concentrates on predicting bead features and controlling process parameters of wire based direct energy deposition process by means of analytical and empirical methods based on process parameters, material properties and deposition strategy in order to modify and develop the quality of final product with higher precision and efficiency rate.
