Fast heating: Based on the principle of high-frequency induction, the welding site can be heated to the required temperature in a few seconds, greatly reducing the welding time. Energy efficiency ratio: compared with the traditional welding method, the energy utilization ratio is higher, reducing energy consumption, suitable for continuous production line, greatly enhances the overall production efficiency. Stable welding quality: rapid heating reduces the area of oxidation and heat exposure, reduces powder slag and other defects,ensures the strength and sealability of the joint. High degree of equipment automation, support one-touch operation, reduce the technical threshold, adapt to the needs of welding of shaped pipes or precision parts by adjusting the induction coils. welding strength and stability, high-strength connection: for example, the saw blade can withstand high axial force and torque after welding to ensure cutting stability.
