Abstract
Existing designs of inductors for induction surfacing of thin elements of flat parts, including shaped discs, are considered and analyzed. New designs of inductors and heating systems developed by the authors to reduce the energy content to improve the surfacing process efficiency and deposited metal quality, are described for induction surfacing of thin steel toothed discs.
Keywords: induction surfacing, brazing, designs of inductors, heating system, flat parts, discs, surfacing efficiency, steel and ferrite magnetic cores, electromagnetic and heat screening
