ABSTRACT:
A core for an inductor or transformer includes a number of concentric turns of a ferromagnetic strip material. An inner core portion (13) consists of a non-amorphous material and an outer core portion (27) consists of an amorphous material. The transition between the two core portions (13, 27) is formed by a welded joint between the overlapping outer (17) and inner (15) end portions of the outer turn of the inner core portion (13), and with the inner end portion (19) of the inner turn (33) of the outer core portion (27) disposed therebetween.
