Electromagnetic Transient-Thermal Modeling of High-Frequency Induction Welding of Mild Steel Plates
High-frequency induction welding (HFIW) is a fast, energy-efficient process that is currently being used to weld pipes, primarily used in oil and gas lines. This work focusses on apprehending the process parameters for the feasibility of welding of flat mild steel plate with a fine refinement of weld structure using HFIW. This multi-physics problem is analyzed by three-dimensionally coupled electromagnetic transient-thermal finite element analysis to understand the electromagnetic heat transfer phenomena and melting. The simulations were done through EMS 2018 add-on package after developing an assembly model in SOLIDWORKS. The magnetic field intensity, magnetic flux density, temperature distribution, and time-temperature plot were obtained and the results are found to be at a good agreement with literature. The skin and proximity effect along with hysteresis losses are considered for the development of the model. Suggestions are made for a better working window with proper welding conditions.
