Construction in which deposits of weld metal are applied
to the surface of base metal for the purpose of:
(a) restoring the thickness of the base metal for strength
consideration; or
(b) modifying the configuration of weld joints in order

and UW-33(b) shall be performed in accordance with the
following rules:
(1) A butt welding procedure qualification in accordance
with provisions of Section IX must be performed for
the thickness of weld metal deposited, prior to production
welding.
(2) All weld metal buildup must be examined over
the full surface of the deposit by either magnetic particle
