Therefore, in order to perform a bending test on the fillet weld joint shown in Fig. 1, 1. Among the methods shown in ``rIs z 2248 r Metal Materials - Test Methods'', it is conceivable to use a method similar to the method for winding. Figure 2 is the above JIS
This diagram illustrates the method of Z 2248.The test bead t is applied to the winding mold d, and the bending test is performed by winding it around the head of the mold (the part where the test piece is wound) having a predetermined radius r. It shows. (B is a stand.) However, if we try to apply the above method to the test piece as shown in Fig. 6, the test piece t as shown in Fig.
Because the part near the head of mold d is wrapped in two layers, the part of the base material away from the head of the mold is bent, not the welded part, and it is not possible to perform a bending test on the welded part. was not appropriate and improvement was desired. (In Figure 6, t is the test piece before being bent, f is the fillet weld joint, d is the winding type, r is the radius of the arc of the mold head, t' is the test piece after being bent, and b is the stand. The object of the present invention is to solve the problems encountered when applying the above-mentioned conventional winding method and to provide a suitable method for imparting bending to a fillet weld joint and a device therefor.

As mentioned above, while holding down the two-ply part connected to the joint of the test piece attached to the board (wrapped in a mold) with a roller,
In the figure, when the lever is turned in the direction of the arrow, the test piece is wrapped around the test piece and bent around the weld, which is effective as a bending test for the joint. In addition, in order to make the bending work easier (to save bending force), you are free to use a long lever to extend the length of the lever to L, or to add an auxiliary lever. be. According to the method of the present invention, due to the effect of the roller that rotates while holding down the test piece, the test piece does not bend from a position away from the weld joint, as was the case with the conventional winding method, and the welding It becomes possible to evaluate the bending of the part.

FIG. 4(b) is a perspective view of an apparatus for carrying out the test piece bending method of the present invention. 2 is a part where a test piece having a predetermined circular arc cross section is wound around one end of the substrate. Reference numeral 5 denotes a pair of levers which can be rotated about the center line of the arc, sandwiching the test piece winding section, and whose tops are fixed to each other by a connecting member 6 to form a gate shape. In order to firmly attach the board, it is also possible to make only the side edges of the board thicker than the other parts. The coupling member 6 may be a plurality of tubes to strengthen the lever, or may be in the form of a long plate. The length of the lever can be increased by attaching an auxiliary lever (not shown) for refilling. 4 is a test piece holding roller that is attached to the gate-shaped lever parallel to its pivot axis and rotates as the lever rotates.
