Abstract

PURPOSE:To enable the obtaining of sufficient penetration at the welding of both tubular bodies and enable the defect-free joining by cutting away the support fitting of the backing ring tentatively supported to the end part of one tubular body then fitting the end part of the other tubular body to the backing ring. CONSTITUTION:The lower half part in the axial center direction of a backing ring 5 with its welding 9 being faced upward is fitted to the inside circumference of the top end part 1a of a lower pile 1 and is pushed until its support fitting 8 abuts against the top end face 1a of the lower pile. Next, root-spacing holding beads 11a- 11d are formed between the respective fittings 8 integrally with the ring 5 onto the face 1b, after which the fittings 8 are cut away by a gas torch or the like. Next, the slag of the beads 11a-11d is removed and its height is so controlled by a grinder as to come within the specified value. After this, the bottom end part 2a of the upper pile 2 is fitted to the upper half of the ring 5, after which the top end part 1a of the lower pile 1 and the bottom end part 2a of the upper pile 2 are semi-automatically welded, whereby the lower pile 1 and upper pile 2 are joined in the state free from any welding defect.
