Uniform Magnetic Heating of Work Pieces0 pages

Equipment Technology
Industrial processes like electron beam or laser welding and surface hardening
require heating of the work piece. For these heating processes pro-beam is applying
the UMH (uniform magnetic heating) technology, a patented technology used in
many industrial applications.
Machines utilizing the homogeneous magnetic heating (UMH) technology help to
optimise the production processes of high quality products. Due to the homogeneous,
controllable and tension free heating of work pieces prior and after the electron
beam or laser welding it opens up new possibilities for welding and heating
applications.
Homogeneous magnetic heating avoids internal tensions and deformations of the
work pieces. UMH machines built by pro-beam optimise the production process of
various applications in the industrial heating technology. Disadvantages of conventional
heating technologies can be overcome.
Traditional heating technologies – including inductive heating – suffer from internal
heat gradients. Inhomogeneities of the heat distribution in the work piece are
caused by the skin effect or the thermal conductivity of the material. Traditional
technologies are characterized by large temperature gradients, the risk of mechanical
deformation and high energy consumption.
With UMH systems made by pro-beam the work pieces are heated homogeneous.
The technology is based on the effect of hysteresis losses. They lead to heat generation
in materials that are exposed to an alternating magnetic field. This innovative
technology is controllable, has higher efficiency than traditional methods and is
more flexible when integrated into industrial manufacturing processes.
