Ferrite rods are usually made of ferrite materials, and common types include manganese-zinc ferrite (MnZn) . This type of material has a high magnetic permeability and electrical properties suitable for high-frequency environments. It can work stably in the frequency range of 200kHz to 500kHz, and adapt to the high-speed operation requirements of welding pipe equipment.
During the high-frequency induction heating process, the Ferrite rod can effectively guide the current to flow along the edge of the pipe wall and concentrate the energy on the part to be welded. By enhancing the skin effect and proximity effect, the Ferrite rod promotes the rapid heating of the weld area, achieves full melting of the edge, and ensures the welding strength and forming quality. At the same time, it can also prevent the induced current from diffusing in the pipe, reduce energy loss, and improve overall energy efficiency.
Selecting a Ferrite rod with stable performance and matching material is of great significance for improving the thermal efficiency of the welding process, controlling the quality of the weld, and extending the life of the equipment. Its parameter design needs to be customized according to the pipe specifications, welding speed and frequency requirements to achieve the best use effect.
Impeder Cooling
All of our impeders are designed to ensure effective cooling and protection of the ferrite core inside the impeder. It is essential that ferrite is cooled efficiently to maximise the welding efficiency and maintain stable parameters for product quality.
1. What is Ferrite Impeder Rods
The Impeder is constructed of Ferrite material and is an essential accessory for use in high frequency welding of tubes and pipes. This material best meets the demanding requirements of high frequency welding. The Impeder lowers the reluctance of the magnetic path, thereby saving energy and improving overall process efficiency.Cores provide an ideal magnetic path even at high temperatures. High saturation flux combined with high resistance reducing eddy current losses improves mill efficiency. It's high density construction adds the mechanical strength for long life in the severe operating environment in a steel tube mill.

Coolant should be clean, preferably filtered. A pressure will ensure adequate cooling under most operating conditions. Coolant flow requirements vary widely due to inlet temperature, weld power, frequency and weld area geometry. In high power density situations and at high ambient temperatures, a small chiller for impeder and work coil coolant can greatly improve efficiency.
A high material permeability to ensure optimum flux concentration.
A high saturation induction at the working temperature which determines the maximum field in which the ferrite can usefully perform.
Ferrite impedance cores from Chinese manufacturers can help you achieve better and more efficient welding.
