Ferrite Impeder Rods/Impeder Cores for High Frequency Welding

Ferrite impeder core PRODUCTS FOR HIGH FREQUENCY WELDING OF TUBES ASSEMBLY IMPEDERS ,THROUGH FLOW IMPEDERS

Ferrite impeder cores are used for concentration of magnetic flux in high frequency, RF, induction welding of steel tubes and pipes. In this application ferrite core experiences temperature upto 150°C and the core properties must be optimized for this environment. 

Ferrite are available in length options of 200mm, 230mm 

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.

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.

Cooling by air or other gas is not recommended, but can be useful in special situations where the presence of water inside the tube cannot be tolerated. Gas, such as nitrogen, have a density that is at least 1,000 times less than that of water, so coolant volume must be increased accordingly.

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.
