Pre-Heating for Welding
Advantages of Induction Heating:
1)The induction heating has a fast heating speed. Compared with the traditional ceramic sheet heating, due to the large energy density, the heat treatment time period can be shortened, and the work efficiency can be improved to a certain extent.
2)The energy of induction heating can penetrate the surface of the workpiece to the inside of the metal, which can reduce the temperature difference between the core and the surface to a large extent.
3)The advantages of induction heating under the working conditions of large pipe diameter and large wall thickness can be more prominent.
4)The induction heating temperature is uniform.
5)The temperature controllability of induction heating is better, closed-loop temperature control and temperature curve collection can be realized, and the processing parameters can be intelligent.
