Induction Preheat Welding Machine

    The intelligent variable frequency induction heating system has powerful functions and superior performance, suitable for various special occasions.

    Preheating and post-weld heat treatment of special steels are important applications of induction heating. Preheating steel before welding can reduce stress, increase welding strength, and prevent cracking, while post-weld heat treatment is used for processes such as dehydrogenation, annealing, tempering, and quenching. Examples include preheating for automatic welding of circumferential seams, preheating for anti-corrosion coating at interfaces, welding preheating for offshore platforms, rotor hot disassembly and assembly, post-weld dehydrogenation, general heating, post-weld heat treatment, straightening, hot fitting, hot disassembly, heat penetration, crystal growth, and thermal coating.
