Abstract
PURPOSE: To obtain the captioned composite material of high quality with high welding efficiency by so inserting a hollow impedance of a specified length composed of magnetic material between a core material of tubular form or the like and a tape-form outside covering material that its center aligns to the center of a high frequency induction coil.
CONSTITUTION: After an outside covering material 2 is formed in tubular form around a core material of wire- or tube form such as of iron, copper or other, it is inserted into a high frequency induction coil 4, and an impedance of a length about 5 times the outside diameter of the outside covering material 2 composed of magnetic material such as of ferrite is inserted between the core material 1 and outside covering material 5 in such a manner that its lengthwise center alings nearly to the center of the induction coil 4, thence the seam of the outside covering material 2 is welded by a high frequency power source 7. This results in the increased impedance of the inside surface of the outside covering material 2, decreased inside circumferential current i23 and current i3 of the core material 1 and improved welding effect and efficiency. It is equally well that the lengthwise center of the impedance 18 is placed in the position of a contactor 19 and welding is done through direct current supply in place of the induction oil 4. The composite material is obtained through drawing with dies.
