regularly enough to maintain the special skills required to set up or to conduct the tests. AWS D1.5-96
requires similar qualification, except in the case of Fracture Critical Members. Under Section 12.16.1.2,
testing of Fracture Critical Members must be done by either a qualified Level II under the supervision of
a qualified Level III, or by a Level III certified by ASNT, unless the Engineer accepts other forms of
qualification.
(3) The following definitions, from ANSI / ASNT CP-189, apply to the various NDT Levels:
NDT Level I - An NDT Level I individual shall have the skills to properly perform specific
calibrations, specific NDT, and with prior written approval of the NDT Level III, perform
specific interpretations and evaluations for acceptance or rejection and document the
results. The NDT Level I shall be able to follow approved nondestructive testing
procedures and shall receive the necessary guidance or supervision from a certified NDT
Level II or NDT Level III individual.
NDT Level II - An NDT Level II individual shall have the skills and knowledge to set up and
calibrate equipment, to conduct tests, and to interpret, evaluate, and document results in
accordance with procedures approved by an NDT Level III. The Level II shall be
thoroughly familiar with the scope and limitations of the method to which certified and

5. INSPECTION CATEGORIES AND TASKS.
a. General. The inspector assigned responsibility for the welding of the project should review and
understand the applicable portions of the project specifications, the contract design drawings, and the
shop or erection drawings for the project, as appropriate. The inspector should participate in a pre-project
meeting with the contractor to discuss the quality control and quality assurance requirements for the
project. A record should be kept of all welders, welding operators and tack welders, welding personnel
qualifications, welding procedures, accepted parts, the status of all joints not accepted, NDT test reports,
and other such information as may be required. The inspector's duties can be assigned or placed into
four general categories, by time period: pre-project inspection for general welding operations, inspection
prior to welding a particular joint, inspection during welding of the joint, and inspection of the completed
joint.
b. Pre-project Inspection. A pre-project inspection should be conducted of the fabricator's and
erector's facilities and operations to verify the adequacy of their welding operations. The scheduling of
this inspection should be well before welding is scheduled to begin, allowing time for necessary
corrections and improvements by the contractor before welding begins.
(1) Personnel. The inspector should verify that all applicable welder, welding operator and tack
welder qualification records are available, current and complete, and that any required special
supplemental qualification tests, such as mock-ups, have been passed. Requalification is required for
any welder, welding operator or tack welder who has, for a period of six months, not used the process for
which the person was qualified. Each person performing welding should have a unique identification
