Preheating Turbine Blade for Welding

Induction Preheating Turbine Blade for Welding Application

Objective: Induction PreHeating a turbine blade to 1850 ºF (1010 ºC) for a welding application Material : Steel turbine blade Temperature: 1850 ºF (1010 ºC) Frequency: 305 kHz Induction Heating Equipment: DW-UHF-6kW-I 150-400 kHz induction heating system equipped with a remote heat station containing two 1.5 μF capacitors. - A single position one-turn induction heating coil designed and developed specifically for this application Process The single position one-turn induction heating coil was designed to heat the tip of the turbine blade. With a 6kW induction heating power supply, the turbine blade was heated to temperature within the targeted time of one minute. Results/Benefits  Speed: The client wanted the part heated to temperature within one minute, which the process achieved - Precision: The client desired uniform heating across the tip of the blade, which was attained with the proposed process - Part quality: The end result is a preheating process that allows the part to move quickly to the welding step while meeting all quality requirements

This induction heating application shows the preheating of steel pipe before welding with MF-25kw (25kW) air-cooled power supply and air-cooled coil.  Inductively preheating of the pipe section to be welded ensures faster welding time and a better quality of the welding joint. Industry: Manufacturing Equipment: MF-25kw air cooled induction heating system Time: 300 secs. Temperature: Required from ambient temperature 600 ° C +/- 10 °C  (1112° F/ +/- 50°F) Materials: Steel pipe Details for butt-welded steel pipe: Total length: 300 mm (11.8 inch) DIA: 152.40 mm (5.9 inch) Thickness: 18.26 mm (0.71 inch) Heating length: 30-45 mm from middle (1.1 – 1.7 inch) Details for butt welded steel plate. Total size: 300 mm (11.8 inch) X 300 mm (11.8 inch) Thickness: 10 mm (0.39 inch) Heating length: 20-30 mm (0.7-1.1 inch) from middle. Fixture details for butt welded steel pipe: Material: Mica. Total Size: 300 mm (11.8 inch) X 60 mm (2.3 inch) Thickness: 20 mm (0.7 inch) Withstands temperature of 900 °C (1652°F) Process: We are using our  MF-25kw air cooled induction heating system which allows to easily move the system and the heating coil to various welding locations, without the need to provide additional water cooling systems or hoses. Induction heating provides consistent heat throughout the process. The preheat temperatures can be easily measured with temeperature monitoring tools. The induction heating method is very efficient because it  minimizes the heat loss that often occurs during other heating methods.
