Simulation of induction heating in manufacturing

Abstract: Induction heating has been used during the past three decades in the industry. Because of fast heating and good reproducibility it is used in heat treatment applications, in bulk heating processed, as well as for special applications in the food and chemical industry. Local heat treatmend by induction on repair welded aerospace components is one example of induction heating in manufacturing. Numerical simulation of induction heating enables optimisation of the process variables. Electromagnetic- thermal modelling of induction heating using finite element method is presented in this thesis work. To be able to compute the temperature history within tight tolerances, an accurate model is needed. Well controlled and documented test-cases of electromagnetic induction heating are few in the literature. The first part of this thesis was therefore done to validate the induction heating model. The work was then extended to include simulation of a manufacturing process chain.
