作業である。It is known to use consumable inserts for the root pass of butt welds in tubes. The consumable insert requires cutting to length, forming into a ring of a predetermined diameter, and fitting into the tube. This is a time consuming and difficult task.

部を突合セ溶接することから成っている。According to the present invention, the method for butt welding the ends of a tube includes preparing a ring of welding material having a shaped end surface in its radially inner portion, and forming a surface on the end of the tube that complements the formed end surface of the ring. , the ring is inserted between the ends of the tube, the ends of the tube are pulled together to hold the ring between the ends of the tube, the radially outer portion of the ring surrounds the end of the tube, and the ring is melted. This consists of butt-welding the ends of the tube.

ることから成っている。Preferably, the butt welding process involves forming the ring with an inner diameter substantially equal to the inner diameter of the tube end, and forming a groove in each end face of the ring at the inner periphery of the ring to provide a seating area for each tube end. It consists of making.

有利には、管の端部を取囲むリングの半径方向外部分は
、断面が三角形である。Advantageously, the radially outer part of the ring surrounding the end of the tube is triangular in cross-section.

is formed. The end 4.5 of the tube with complementary right-angled edges fits into the groove or recess 2.3. The inner diameter of the weld ring is substantially equal to the inner diameter of the tube end, and the diameter of each groove or recess is equal to, but not less than, the outer diameter of the respective tube end.

与えて溶接作業を行う。The part of the ring 1 surrounding the end of the tube is preferably triangular in cross section, the apex 6 of the triangle lying in the plane of transverse symmetry. The outer part of the ring can have other contours, for example semi-circular, but the apex 6 can be manually welded or
A triangular cross section is advantageous because it creates a landmark for positioning the orbital welding head that melts the ring at the end of the tube. A jig or support may be provided to hold the end of the tube within the groove or recess during the welding operation. A welding ring is fitted to one end of the tube by first holding the ends apart and positioning the end of one tube within a groove or recess in one end face of the ring. The other end of the tube is then moved to seat in a groove or recess in the other end face of the ring. This holds the ring in place and gives the operator more freedom to perform the welding operation.

るに過ぎない。Alternatively, the ring may have a rhomboidal cross-section, seated in a groove formed by chamfering or bevelling the end of the tube. In such a construction, the ring first seats in the groove and the adjacent ends of the tube are spaced apart by a small gap. The upper glide-shaped portion of the diamond-shaped cross-section ring surrounds the end of the tube, with the apex of the triangle lying substantially in the plane of transverse symmetry. As mentioned above, the operator only needs to melt the ring to obtain a weld through the wall thickness of the tube.

突合せ溶接に予め形成した溶接リングを使用することに
より、既存の技術に比して多くの利点が生ずる。The use of preformed weld rings for butt welding provides many advantages over existing techniques.
