Description

Technical Field

[0001] The utility model relates to the technical field of heating devices, in particular to a battery heating belt for preheating before welding. Background Art

[0002] Electromagnetic induction heating is an environmentally friendly, energy-saving and efficient heating method. Its principle is to convert alternating current into an alternating magnetic field through an inductor coil, and then act on a metal workpiece in the electromagnetic field to generate a closed rotating current (eddy current) in the metal workpiece. The heat generated by the rotating current heats the metal workpiece, causing the metal workpiece to heat up rapidly in a short period of time to achieve the heating purpose.

[0003] According to welding requirements, pipe workpieces need to be preheated at the welding position before welding. There are generally two ways to weld pipes, namely, connecting welding at the ends of the pipes and welding at the joints of the pipe bodies. Regardless of which welding method is used, the pipes need to be preheated before welding. The existing preheating device before welding cannot be adaptively adjusted to heat according to the diameter of the pipe and the welding method of the pipe, which will cause uneven heating of the plate and affect the subsequent welding effect.
