ものである。Not only pipe end welding but also automated welding work is different from artificial welding work in that the purpose cannot be achieved unless preparations are completed in advance. In the case of automation, once a command is given. For example, it is almost impossible to make corrections until the work is completed. Therefore, the advance preparation method determines the quality of the product. In this respect, in artificial welding work, a manual adjustment method according to the transition of the work is used. Therefore, the quality of these products depends on the skill level of the operator, the intuition,
It was done by the comprehensive higher technology acquired.

る円筒管体の管端溶接用ホルダー。1. A connecting member 3 is fixed to one side of an outer circumference of each circular arc piece 2 obtained by dividing the cylindrical body 1 into at least three parts in parallel with an axis line, and a part of the connecting member 3 is used as a hinge body 4 and divided. Each of the circular arc pieces 2 is rotatably pivoted so as to be integrated, and forms one end of a series of circular arc piece groups. Locking shaft 7 that has an opening / closing handle 6 that protrudes and uses the connecting member 3 of the arc piece 2 that forms the other end of the arc piece group as a bearing
Wherein the lock part 5 of the form so that it can be desorbed, further, from one end of the connecting member 3 of the, with scan-flop line <br/> emission axis acts on the axial direction, so as to be freely and out Is inserted into the female screw of the fixing body 8 which is inserted into the male screw of the adjusting shaft 10 having the operation handle 9 screwed in from the opposite end portion thereof. 1. A holder for welding a pipe end of a cylindrical pipe body, wherein a fixing screw 11 is threadedly penetrated at a tip thereof so as to orient the axial line of the cylindrical body 1 formed by the arc piece 2.
