Welding seam induction preheating equipment

Overview of Induction Preheating Equipment for Weld Seam Welding The pre weld induction preheating equipment is mainly used to heat the welded parts locally or as a whole before welding, in order to reduce the cooling rate of the welded joint, avoid the formation of hardened structure, reduce welding stress and deformation, and prevent the occurrence of welding cracks. Induction preheating has the advantages of energy saving, fast heating speed, and high degree of automation compared to traditional flame heating, resistance heating, and other methods.   Working principle and advantages of induction preheating equipment Induction preheating equipment is based on the principle of electromagnetic induction heating, which generates a changing magnetic field in the induction coil through alternating current, causing Joule heating of the conductive material inside the workpiece, thereby achieving the heating purpose. This method allows for direct heating without the need for interme…
