Impeder Rods for High Frequency Welding

Fiberglass+Ferrite+copper end

Return flow of cooling liquid ( round , square and rectangular sections )

Through flow impeders are the most common type of impeders and are a relatively simple concept, our designs ensure maximum high quality ferrite mass is placed within a well-constructed assembly. The result is improved performance, saving you money and increasing productivity.

mpeders must be always well proportioned and always together with inductors since together they create the electromagnetic inductive circuits that allow a good and efficient induction welding.

The high-frequency welding impeder is a critical component within welded tube production lines, typically installed inside the pipe near the weld seam. Its primary function is to guide and concentrate the high-frequency current along the strip edges, preventing current from dispersing through the center of the tube. This intensifies both the skin and proximity effects, ensuring fast and focused heating at the weld zone.

Impeders are generally constructed using high-permeability ferrite materials or iron-core assemblies, and can be configured in various shapes and sizes to suit specific production needs. A well-designed impeder improves energy efficiency, enhances weld consistency, and stabilizes the heating process—leading to stronger, cleaner welds and higher line speeds.

In addition to improving electrical efficiency, quality impeders offer excellent thermal resistance, mechanical strength, and magnetic performance, allowing them to withstand the demanding environment of continuous high-frequency operations. Proper selection based on parameters such as pipe diameter, operating frequency, and welding power is essential for achieving optimal welding results.

All of our impeders are designed to ensure effective cooling and protection of the ferrite core inside the construction. It is essential that ferrite is properly cooled  to maximise welding efficiency and maintain stable parameters for product quality.

Standard through flow impeders – Ferrite is totally enclosed inside the casing  

Exposed Ferrite impeders – around 10-15% of the end of the ferrite protrudes from the casing  

We have standard male imperial couplings but can offer metric or other threads on request.

Impeders are available in length options of 230mm, 330mm & 430mm.

Impeder Cooling: Semua impeder kami dirancang untuk memastikan pendinginan dan perlindungan inti ferit di dalam impeder secara efektif. Ferit harus didinginkan secara efisien untuk memaksimalkan efisiensi pengelasan dan mempertahankan parameter yang stabil untuk kualitas produk. Pendingin harus bersih, sebaiknya disaring. Tekanan akan memastikan pendinginan yang memadai dalam sebagian besar kondisi pengoperasian. Persyaratan aliran pendingin sangat bervariasi karena suhu masuk, daya las, frekuensi, dan geometri area las. Dalam situasi kepadatan daya tinggi dan pada suhu sekitar yang tinggi, pendingin kecil untuk pendingin koil kerja dan penghambat dapat sangat meningkatkan efisiensi. 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.
