Lets address one thing at a time.
A CWI is not qualified by virtue of the CWI to certify LII visual personnel.
http://files.aws.org/certification/docs/b5.1-03.pdf If it were an SCWI there is an arguement that could be made based on the same document.
Refer to table 1.
B31.3 Don't have 04 with me, this is out of 06 so you need to verify language.
342 EXAMINATION PERSONNEL
342.1 Personnel Qualification and Certification
Examiners shall have training and experience commensurate
with the needs of the specified examinations.(note 1)
The employer shall certify records of the examiners
employed, showing dates and results of personnel qualifications,
and shall maintain them and make them available
to the Inspector.
note 1:For this purpose, SNT-TC-1A, Recommended Practice for Nondestructive
Testing Personnel Qualification and Certification, may
be used as a guide.
By this language it does not directly require SNT-TC-1A.
B31.3 does make another modification to this statement that is often overlooked.
343 EXAMINATION PROCEDURES
Any examination shall be performed in accordance
with a written procedure that conforms to one of the
methods specified in para. 344, including special methods
(see para. 344.1.2). Procedures shall be written as
required in the BPV Code, Section V, Article 1, T-150.
The employer shall certify records of the examination
procedures employed, showing dates and results of procedure
qualifications, and shall maintain them and make
them available to the Inspector.
That is for the procedures, and the specific methods tie back to section V as well.
344.2.2 Method. Visual examination shall be performed
in accordance with the BPV Code, Section V,
Article 9. Records of individual visual examinations are
not required, except for those of in-process examination
as specified in para. 344.7.
It's not just the opening statement in TC1A that you have to satisfy. All caveates as found in section V also apply.
If the level III is PT, MT, RT, the standard LIII does satisfy the intent and requirements for those methods.
Where I see a problem is in the visual.
