46、 applicable. Duringthe first step, which is a test for ductility of the weld, except as allowed by 7.3.5, 7.3.6, and 7.3.7, no cracks or breaks on the insideor outside surface at the weld shall be present before the distance between the plates is less than two thirds of the specified outsidediameter
47、 of the pipe.As a second step, the flattening shall be continued as a test for ductility away from the weld.
