In addition to straight pipes, there are many different types of pipes used in piping work, such as elbow pipes, T-shaped pipes, and reducer pipes. Also, many so-called cut pipes are used, in which the groove line of the straight pipe is not perpendicular to the pipe axis.

保しているのが実情である。 The reality is that outer clamps used as centering jigs for these many welded joints must be prepared in several types to match each type of pipe, such as straight pipes and straight pipes, and straight pipes and irregularly shaped pipes. be. In addition, in welded joints for jointed pipes such as a jointed pipe and an elbow pipe, or a jointed pipe and a T-shaped pipe, there is no outer clamp that can be used, and the joint is held in place using a metal arrow, a horse, etc. The reality is that accuracy is ensured.

However, the technology proposed in Japanese Utility Model Publication No. 57-9040 is that a two-piece clamping device equipped with a guide plate on the lower frame rotates horizontally around a joint hinge.
This is a mechanism that adjusts the clamp angle between two strips.
This becomes an extremely difficult task if the bending direction of the pipe is other than horizontal.

響する。 In addition, the technology proposed in Utility Model Application Publication No. 59-54192 is
It is difficult to maintain and fix the root spacing to a predetermined dimension. This is because, not only in curved or irregularly shaped pipes, but also in the case of straight pipes, the tip of the bolt used to tighten and fix the pipe body is conical, but when the bolt is turned, the contact point moves. The route spacing changes. In addition, the root spacing also shrinks due to clamp welding, which greatly affects welding quality.

に問題があつた。 Furthermore, the conventionally used Kanaya and Uma (strong back jigs) are only used when conventional outer clamps cannot be used, such as for straight pipes and irregularly shaped pipes, cut pipes and irregularly shaped pipes. This posed problems in terms of quality and efficiency, as it required a change in the material of the base material, as well as bead polishing and repair after welding and removal of the weld, in order to weld the weld near the weld joint.
このように、すべての溶接継手に使用可能なア
ウタークランプは従来存在しなかつたので、配管
工事を合理化することは困難であつた。 As described above, since there has been no outer clamp that can be used for all welded joints, it has been difficult to streamline piping work.
