If RT is used in lieu of the
prescribed bend tests, the weld reinforcement need not to
be ground or otherwise smoothed for inspection unless
its surface irregularities or juncture with the base metal
would cause objectionable weld discontinuities to be obscured
in the radiograph. If the backing is removed for
radiography, the root shall be ground flush (see 5.24.4.1)
with the base metal.
