Preheating Device

Medium Frequency Induction Heating System is a specialized high-efficiency heating equipment developed by Nanjing Auto Electric Co., Ltd. specifically for the production of large cylindrical vessels, towers, and wind turbine tower piles. Both the heating power supply and the adjustable-radius induction sensor (preheating belt support) are designed with bases equipped with universal wheels, facilitating movement between various welding stations. Under certain conditions, it can achieve a one-to-two configuration, simultaneously preheating two weld seams. The AUTO medium frequency induction preheating system is compact and lightweight, making it easy to move flexibly.

This system utilizes the principle of medium frequency induction heating, specifically for preheating, heat preservation, and post-heating of weld seams during automatic welding of cylindrical vessels. It is a dedicated high-efficiency equipment for improving the preheating efficiency of cylindrical vessel welding and ensuring welding quality. It is an ideal heating equipment for automatic welding of thick-walled and alloy steel cylindrical vessels, promoting digitization in welding processes.
