Abstract

The thesis deals with the proposal of location of heating elements for annealing the last weld. The introduction part describes mathematical modeling of heat processes. The first and the second part describes thermal problems and methods of mathematical modelling and their solutions. In the next part is about of program COMSOL Multiphysics and his examples of utilization. Chapter five acquaints with company Svarservis s r. o. The following part of the thesis is focused to calculate heating power of heating element. In the part seven is shown procedure of setting of boundaries conditions and material properties. In the last chapter is solved the problem and compared with real values.
