It is used to measure the misalignment of the groove. The misalignment inspection gauge 60 includes a substrate 64 and a misaligned measuring member 65. One side of the substrate 64, which is a substantially rectangular flat plate, extends linearly from one side 66 toward the other side 67, and a flat portion 68 that comes into contact with the welding material 61 as a reference for misalignment measurement. It comprises a concave portion 70 extending linearly from the other side 67 toward one side 66 and having a shorter distance from the opposing side 69 than the flat portion 68.

を測定し検査することは不可能である。However, inspection may not be possible with the above-mentioned conventional techniques. For example, when automatically welding a steel pipe or the like used as a conduit for supplying city gas, a backing metal is often applied to the inside of the groove in order to hold a molten welding material. A system has been developed that automatically welds the backing metal while holding the backing metal inside the pipe. As shown in FIG. 16, in a state where the backing metal 75 is attached to the welding groove, the backing metal 75 becomes an obstacle and the insertion type gauge 51 as shown in FIG. 14 cannot be inserted. For this reason, the plug-in gauge 51
Root interval 50 of groove of welding materials 61 and 62
Is impossible to measure and inspect.

ゲージを別に製作しなければならない。A misalignment inspection gauge 60 as shown in FIG. 15 is manufactured so as to be suitable for measurement at a welding groove having a specific groove width. For this reason, the flat portion 68 and the measuring member 6
The gap with the groove 71 into which 5 is inserted is fixed, and the measurable gap is limited. For example, a conventional pipe with a nominal diameter of 600 mm is used as a pipe for city gas, which is a welding material. However, when a nominal diameter of 750 mm is used, the groove width of welding becomes large, and the conventional pipe is used. A large misalignment inspection gauge having a longer measurement position interval than the difference inspection gauge 60 must be separately manufactured.

It is necessary to perform various types of inspections, such as inspection of the provided taper.
Inspection involves the complexity of having to prepare and use several types of inspection gauges, in addition to the general measuring tools such as physical differences, rulers, protractors, and calipers. There is also a demand to minimize the types of tools used for welding inspection.

隔３４を細かく測定することができる。Regarding the length of the scale line of the main scale scale 8, a scale line having a length of 2 mm from the periphery is displayed at intervals of 5 mm, and the other scale lines are displayed with a length of 4 mm. Generally, the length of a scale line is often displayed every fifth to tenth line longer than other scale lines. In the case of this embodiment,
Since the vernier scale 12 is superimposed on the inner side in the radial direction of the main scale 8, even if a long scale line is displayed, the vernier scale is hidden by the vernier plate and cannot be distinguished. As shown, short scale lines are displayed at 5 mm intervals.
The vernier scale 12 is scaled by 10 scales on both sides from the center so that the scale of the main scale 8 is a vernier scale.
From the number of graduation lines between the center scale of the vernier scale 12 and the center point 35 of the main scale graduation 8 and the vernier scale 12 and the main scale graduation 8, the main scale graduation 8 to be read by the vernier reading method. By using a value one digit lower than the minimum scale unit of 1 mm, the route interval 34 can be finely measured.
