Blankenship, Elliott K. Stavasp.info Why do you need an inductor for induction heating?The inductor in which the heating material is to be placed should allow easy insertion and removal of the material. While calculating power supply capacity, the specific heat of the material to be heated, the mass of the material and the temperature rise required are to be considered.See all results for this questionsp.info What kind of material is used for induction heating?Normally, the induction heating process is used for metals and conductive materials. The non –conductive material can be heated directly. While applied on magnetic materials, heat is generated both by eddy current and hysteresis effect of magnetic materials.See all results for this question
Induction heating process is the non-contact process of heating an electrically conductive metal by generating eddy currents within the metal, using electromagnetic induction principle. As the generated eddy current flows against the resistivity of the metal, by the principle of Joule heating, heat is generated in the metal.See all results for this questionsp.info How is the effective depth of an induction Circuit determined?The heat loss due to conduction, convection, and radiation should also be taken into account for deciding the power supply capacity. The depth penetrated by eddy current into the material is determined by the frequency of the inductive current. For current carrying layers, the effective depth can be calculated asSee all results for this questionsp.info Best Cheap Welder of 2021 - Safe & Professional Welding ...With the unique “Quick-Start” mode, it can achieve arc starting in about 1/5 second only, which saves much more electric power than the linear mode TIG welding current method.
