The paper deals with a new impeder for HF inductive welding of steel tubes. Experimental research has been carried out on generators with impeders made of ferrite. The authors introduce magneto dielectric Fluxtrol instead of ferrite and thus project a new impeder. On the basis of many years of experimental research with impeders, significant energy savings have been achieved when welded in comparison with various ferrite and other impeders. Such savings and welding with less power make it possible for increased production speed of welded tubes.
