要となる。2. Description of the Related Art The surplus formed as a result of the deposited metal during welding rising above the groove dimension at the time of welding requires a certain amount to obtain the desired welding strength. It However, in a test of a welded portion that generally requires a radiation transmission test, if the extra height is too high, the ability to detect internal defects in the weld is lowered, so that the height dimension is severely limited. For example, in the case of a carbon steel or stainless steel pressure vessel manufactured based on the High Pressure Gas Control Act, according to Article 50 of the Specified Equipment Inspection Regulation, 1.5 mm for a base material thickness of 12 mm or less. Less than,
2.5m for objects over 12mm and under 25mm
It is strictly regulated as m or less. Therefore, it is necessary to perform an inspection operation for measuring the excess height of each product and establishing acceptance / rejection.

It is the case of a state. In the figure, 5 is a base material of the welded portion of the pressure vessel, and 6 is a surplus formed on the surface thereof. For the measurement, first, the slide gauge 2 is raised upward, the gauge main body 1 is moved so that the plane position thereof is directly above the extra scale 6 to be measured, and the lower surface of the foot 1a is pressed against the surface of the base material 5. Thus, the gauge body 1 is held in that posture. Next, the slide gauge 2 is lowered, and when the lower end 2a thereof comes into contact with the surface of the extra scale 6, the position of the scale 3 indicated by the ruled line 4 is read. Originally, when the lower surface of the foot portion 1a of the gauge body 1 and the lower end 2a of the slide gauge are at the same level, the ruled lines 4 indicate the zero position of the scale 3 (see FIG. 5). That is, the reading obtained in (1) becomes the height of the extra 6 as it is.

The measurement is performed by the method described in FIG. 6 (1). Although it is carried out according to the above, there are various problems because the base material 5 is not flat. That is,
Depending on the magnitude of this curvature, as shown in the figure, the gauge main body 1 is slightly tilted from the posture in which the entire lower surface of the foot portion 1a of the gauge main body 1 abuts the surface of the base material 5, and the curvature of the base material 5 is slightly increased. It is necessary to devise work such as reducing the influence, and sometimes to take measures such as correcting the measurement result according to the magnitude of the curvature of the base material 5, which complicates the measurement work, and depending on the operator, The measurement accuracy also decreases.

問題点があった。By the way, the pressure vessel in which the management of these extra heights is strictly required is usually cylindrical, and the welded joint portions existing in the axial direction and the circumferential direction thereof are the welded portions having the above-mentioned curvatures. Moreover, since the diameter of the cylinder, the thickness of the base material, and the welding method are multi-branched, the method using the conventional gauge described above requires a great deal of skill and labor for measurement. There was a problem that the time also became extremely long.

ら行うものとして説明する。Next, a method for measuring the height of the extra weld at the welded portion having a curvature by using the gauge shown in FIG. 1 will be described with reference to FIG. FIG. 2 shows a welded portion 5a and a non-welded portion 5 of the base material 5.
Although it is illustrated in the form of using a gauge at both positions of b and b, it is actually measured with one gauge in order. Either of them may be performed first, but here, it is assumed that the non-welded portion 5b is performed.

る目盛３の位置を読み取る。A non-welded portion 5b having the same curvature as that of the welded portion 5a is appropriately selected and both foot portions 11a and 11b of the gauge body 11 are pressed against the surface of the base material 5. In this state, the lower end 1 of the slide gauge 12
2a is brought into contact with the surface of the base material 5. However, since the leaf spring 14 described above is used in this embodiment, if both the foot portions 11a and 11b and the lower end 12a are initially aligned on the same line, the both foot portions 11a and 11b are pressed against the base material 5. Only then, the lower end 12a of the slide gauge 12 is in contact with the surface of the base material 5. In this case, the gauge body 11 comes into contact with the surface of the base material 5 at two points, that is, the point A of the foot portion 11a and the point B of the foot portion 11b. The relative positional relationship between 11 and the base material 5 is determined. Then, in this state, the position of the scale 3 designated by the ruled line 4 is read.

る訳である。Next, the same gauge is transferred to the welded portion 5a and measured. That is, the gauge body 11 is positioned so that the lower end 12a of the slide gauge 12 is brought into contact with the surface of the extra scale 6 to be measured, and accordingly, the extra scale 6 is located substantially at the center of both legs 11a and 11b of the gauge main body. When pressed against 5, the lower end 12a of the slide gauge 12 abuts the surface of the extra scale 6 due to the effect of the leaf spring 14, and the relationship between the gauge body 11 and the slide gauge 12 is maintained in this state, as described above. . Also in this case, since the gauge body 11 contacts the surface of the base material 5 at two points, the point A of the foot portion 11a and the point B of the foot portion 11b, the relative positional relationship between the gauge body 11 and the base material 5 is It can be regarded as the same as the measurement at the non-welded portion 5b. Therefore, if the position of the scale 3 indicated by the ruled line 4 is read in this state and the difference from the read value at the previously obtained non-welded portion 5b is obtained, that is the height of the extra scale 6. .

The ring-shaped chain is provided by inserting a small hole formed in the slide gauge 12 and the slide gauge 12, and is intended to facilitate handling other than during measurement and prevent the gauge body 11 and the slide gauge 12 from being separated and lost. Further, the protruding portion 11c at the left end of the gauge body 11 has its tip formed at a predetermined angle (for example, 60 °), and the angle of the groove portion to be processed prior to the workpiece is inspected. It can be used as a gauge. Reference numeral 7 is an adjustable scale as a dimension display means, and has a structure in which a pointer 71 corresponding to the ruled line 4 in FIG. 1 can be appropriately moved along a groove 72 provided in the slide gauge 12. The pointer 71 is fixed and moved by tightening and loosening the knob 73.

I do. Therefore, next, the welded part 5
Similarly, when the state shown in FIG. 2 is set at a, the reading of the scale 3 indicated by the pointer 71 at that time is obtained as the height of the extra scale 6 as it is. As a result, in the embodiment of FIG. 3, it is not necessary to calculate the difference between the two readings when obtaining the height of the extra reinforcement 6, and the reading at the non-welded portion 5b is recorded for this calculation. There is no need for time and effort.
