Abstract

PURPOSE:To contrive the improvement in quality without vena contracta at a junction part and damage to insulating sealing by a method wherein spiral-shaped internal cylindrical coils and the end sections of double-cylindrical coils consisting of external cylindrical coils are connected by seam welding and a closed loop is made. CONSTITUTION:Internal cylindrical coils 6 are formed by winding several juxtaposed coil strands 3 on the cylindrical surfaces in spiral shape and furthermore, external cylindrical coils 9 are made by winding the same strands 3 on the surfaces of the coils 6 in spiral shape in reverse direction. After simultaneously cutting the coils 6 and 9 into predetermined length, seam welding 14 is applied to the end sections to connect the internal coil and the external coil strands 3 and a closed loop is formed. In this way, the junction part is sufficiently welded and no interlayer short circuit will be caused.
