Hi,
As per Sec.V - T-224, it doesn't require to specify the weld thickness on the film. But As per T-290,weld thickness need to specify on the RT Reports. In your case you can accept the film and all other details shall be specified on the RT reports as per T-290.please find below the extraction of T-224 and T-290 for your reference.

T-291 Radiographic Technique Documentation
Details:
The Manufacturer shall prepare and document the radiographic
technique details. As a minimum, the following
information shall be provided.
(a) identification as required by T-224
(b) the dimensional map (if used) of marker placement
in accordance with T-275.3
(c) number of radiographs (exposures)
(d) X-ray voltage or isotope type used
(e) source size (F in T-274.1)
(f) base material type and thickness, weld thickness,
weld reinforcement thickness, as applicable
(g) source-to-object distance (D in T-274.1)
(h) distance from source side of object to film (d in
T-274.1)
(i) film manufacturer and Manufacturer's type/designation
(j) number of film in each film holder/cassette

Subject: [MW:13257] Identification of thickness on Radiography films.
Dear Experts,
During Interpreting Radiography films at one of my vendor's works, I observed that, there is no identification /indicate thickness of job on film so I rejected the film. As far as generally everyone related field experience persons are know unless identification of thickness on film it is very difficult to know which penetrameter to be used but my vendor is arguing for the same. According to him one of "Level III" person insisit them there is no need to mentioned thickness in Radiography films and it sufficient if it indicate in Radiography interpretion report.
Suppose in piping number of joints/piping spools are comming with verious thickness in same report in such case it is possible to identify required penetrameter ? My anser is no, each Radiography films must be indicat thickness of joint/job. Requested to suggest/advise.
Sincerely yours,
RK Vichare
