The curvature measuring unit 500 may be formed to have predetermined curvature values (for example, 2R and 3R) when the body 100 is provided with two or more points.

In addition, the body 100 may be provided with an alignment measuring unit 600 for measuring the alignment of the member to be tested t and the stepped portion thereof.

Here, the alignment may mean an alignment inspection to judge whether or not the height difference of the surface does not occur flatly when two different members are welded to each other, and on the other hand, May be a flatness test to determine whether or not it is evenly flat.

The alignment measuring unit 600 may be provided on at least one side of the depression 101 formed in the body 100 and may include an alignment ruler 610 and a coupler 620, The alignment can be measured while the protruding portion 610 protrudes from the remaining sides 102 formed on both sides of the depression 101 (see FIG. 7).

The measuring method may be carried out using any one of the remaining sides 102 formed on both sides of the depression 101 for examining the alignment of the first member 10 and the second member 20 welded together, Are positioned on the surface of the first member 10 and the remaining one of the remaining sides 102 is located on the surface of the second member 20 so that the remaining two sides 102 are located between the first member 10 and the second member 20 20, respectively. At this time, if any one of the remaining sides 102 is not closely attached, the step value of the place where the alignment ruler 610 is not attached can be measured.

Here, the alignment ruler 610 may have a numerical value along a longitudinal direction on one side. A guide groove 611 may be formed on the inner side of the alignment ruler 610 to guide the remaining sides 102 formed on both sides of the depression 101 to protrude forward. The guide groove 611 may be formed along the longitudinal direction of the alignment ruler 610.
