Impeder Cores are essential components in high-frequency tube welding systems. Installed inside the steel tube during the forming and welding process, they reduce the magnetic reluctance of the flux path, concentrating the high-frequency magnetic field at the weld seam. This significantly improves welding efficiency while reducing power consumption.
Manufactured from advanced R2KW ferrite material, these impeder cores feature a high saturation flux density, high electrical resistivity, and low core loss, effectively minimizing internal heat generation and ensuring stable, energy-efficient performance during continuous high-frequency welding operations.Their high-density material structure also provides excellent mechanical strength and durability, enabling reliable long-term operation under the demanding conditions commonly found in steel tube and pipe manufacturing facilities.
Impeder Core series is engineered to enhance weld quality, improve energy efficiency, and extend service life in high-frequency induction and contact welding applications.

FAQ
Q: What is the function of an impeder core in high-frequency welding?
A: The impeder core is installed inside the steel tube during high-frequency welding. By reducing the magnetic reluctance of the magnetic circuit, it concentrates the high-frequency induced current along the tube edges, thereby improving welding efficiency, reducing power consumption, and enhancing weld quality.
Q: What are the advantages of R2KW material?
A: R2KW material features a high saturation flux density (500 mT) and high electrical resistivity (3.0 Ω·m), which effectively reduce eddy-current loss and internal heat generation. In addition, its Curie temperature exceeds 200°C, making it well suited for high-temperature welding environments.
Q: What is the difference between the YC series and the YO series?
A:YC Series: Solid rod-type impeder core, typically used for smaller tube diameters.
YO Series: Hollow tubular impeder core, designed for larger tube diameters, with a central channel that can accommodate cooling media for improved thermal management.
