Induction Heating Turbine Fan For Welding

Induction Heating Turbine Fan For Welding With High Frequency Heating SystemObjective To uniformly heat jet engine turbine fan blades to 1800°F (982.2ºC) within five minutes for a welding application Material Jet engine turbine fan blades with 2”(50.8mm) length tip Temperature 1800°F (982.2ºC) Frequency 30 kHz Equipment • DW-MF-15kW induction heating system equipped with a remote workhead. • An induction heating coil designed and developed specifically for this application. Process A four-turn helical coil with a kidney shape is used to provide uniform heat for this application. The turbine blade is placed inside the coil and power is applied for 5 minutes until the top 0.25” (6.35mm) of the blade reaches 1800°F (982.2ºC). An optical pyrometer is used to measure the temperature of the part. Results/Benefits Induction heating provides: • Even and consistent distribution of heat • Faster production rate • Reduces product waste through rapid heat-up and cool down cycles
