Abstract
In the industry, induction hardening of rotationally symmetrical workpieces by a single-shot process is a widespread method. Due to only partial superimposition of the workpiece areas to be heated by the coil, high power densities are often needed there. These lead to local hot spots, amounting to an intensive material stress and often result in a short lifetime of the inductor. In this paper, some numerically investigated models will be presented, revealing approaches, how to reduce mechanical stress in the single-shot coil and thus, enabling an increase of service life.
