What is the specified bending angle for the bending test of welded joints?

You can refer to the standard JB/T 4744-2000, which specifies the parameters for the bending test; the bending angle is 180 degrees

As mentioned above, it is clearly stated in \"JB4744-2000 Mechanical Property Testing of Welding Test Plates for Steel Pressure Vessels\" that the radius of curvature for the bending test is 4 times the thickness of the specimen, the distance between the supports is 6 times the thickness of the specimen plus 3, and the bending angle is 180°.
