induction preheating steel tube for welding

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.  

Induction Preheating Welding Automotive Parts

Induction Preheating Welding Automotive Parts With Induction Heating Equipment Objective To pre-heat the seam of a truck axle to over 300°F within 15 seconds for a welding application and maintain temperature within the welding zone for 15 seconds after the power is turned off. Material Steel truck axle; 350° and 400°F temperature indicating paint;350°, 375°and 400°F temperature indicating “crayons” Temperature 350°F Frequency 75 kHz Equipment DW-HF-35kW power supply, remote heat station with four 1.2 μF capacitors and a specially designed pancake induction coil. Process A fixture was constructed to rotate the axle 400° in 15 seconds and the induction coil was placed above the axle. The circumference of the axle (beneath the coil) was painted with 350° and 400°F temperature indicating paint. While the axle was being rotated, RF power was applied for 15 seconds. All of the paint melted, confirming that the axle temperature was above 400°F. The RF power was shut off and the temperature “crayons” were immediately placed against the axle to monitor temperature. The 400°F crayon did not melt; the 375°F crayon melted for 15 seconds; the 350°F crayon melted for 30 seconds. Results The steel axle was heated to over 400°F within 15 seconds and temperatures above 350°F were maintained for 30 seconds after power was turned off, meeting the requirements of the welding application.
