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
