7.3. SURFACE CONDITION Where possible the contour of the weld surface shall be smooth and uniform to such a degree that on the resulting radiographic image will not get masked or be confused with the image of any discontinuity.
7.4. EQUIPMENT AND MATERIALS The following radiation sources may be used:
Iridium 192 x-ray Machines of any kV capable of penetrating the material being inspected.
The radiation energy employed for any radiographic technique shall achieve the density and IQI image requirements of this procedure.
The equipment manufacturers or suppliers publications, such as technical manuals, decay curves, or written statements documenting the actual or maximum source or focal spot size shall be acceptable as Source size verification. This value shall be used in calculating geometric unsharpness. Incase if the manufacturer data is not available then source size verification shall be carried out as per ASME Sec V Article 2, Para T261.2.
Industrial Radiographic Film Quality requirements such as Kodak T 200/Agfa D5 For Thickness up to 19 mm, Kodak AA 400/Agfa D7 Above 19mm or Equivalent shall be Used as per the Specification T.13.376.796E Sec A4.2.
All unexposed films shall be stored in a clean, dry place and temperature controlled
place in compliance with manufacturers recommendations where the conditions will not detrimentally affect the emulsion. If any question arises about the condition of the unexposed film, sheets from the front and back of each package or a length of film equal to the circumference of each original roll shall be processed in the normal manner without exposure to light or radiation. If the processed film shows fog, the entire box or roll from which the test film was removed shall be discarded, unless additional tests prove that the remaining film in the box or roll is free from pre-exposure fog exceeding 0.30 H&D transmitted density for transparent-based film or 0.05 H&D reflected density for opaque-based film.
Lead Intensifying Screens
The thickness of the screens for Iridium 192 shall be 0.005 Front and Back. The thickness of the screens for x-ray Machines above 125 kV shall be 005 Front and Back. The viewing equipment (illuminator) shall be of the variable high intensity type and shall be capable of viewing film densities within the range specified in paragraph 10. It shall be equipped to prevent light, coming from around the outer edge of the radiograph or through low density portions of the radiograph, from interfering with interpretations.

QQQ AAA TTT AAA RRR
Viewing facilities shall provide subdued background lighting of an intensity that will not cause troublesome reflections, shadows, or glare on the radiograph.
7.5. EXPOSURE GEOMETRY When a radiographic source is centered in the pipe for exposing a butt weld, one
exposure is adequate for the radiographic inspection of the complete weld (SWE/SWV). When the radiographic source is outside but not more than inch (12.7 millimeters)
from the weld surface, at least three (3) exposures separated by 120 degrees shall be made for the radiographic inspection of a complete weld (DWE/SWV).
When the radiographic source is outside and more than inch (12.7 millimeters) from the weld surface, at least four exposures separated by 90 degrees shall be made for the radiographic inspection of a complete weld (DWE/SWV)
When the diameter of the piping containing the weld is 2 inches or less, a DWE/DWV procedure may be used. When this procedure is used and the radiation beam is offset so that the source side and film side portions of the weld do not overlap in the areas of the radiograph being evaluated, at least two exposures separated by 90 degrees shall be made for the radiographic inspection of a complete weld.
When the source side and film side portions of the weld are superimposed, at least
three (3) exposures separated by 60 degrees shall be made for the radiographic inspection of a complete weld.
When smaller diameter, thicker wall pipe is radio graphed, additional exposures should
be made to minimize the distortion of discontinuity images at the ends of the radiographs.
The minimum distance between the source or focal spot and the source side of the object being radio graphed shall be determined by the following formula (using constant units of measurement): D = St/Ug Where: D = Minimum distance, in inches, between the source or focal spot and the source side of the object being radio graphed. S = Size, in inches, of the effective source or focal spot. t = Thickness of the weld, in inches, including reinforcement, plus the distance between the film side of the weld and the film. Ug = Geometric unsharpness.
When t is determined for SWE/SWV and DWE/SWV procedures, the thickness of the single wall and its weld reinforcement shall be used. When t is determined for DWE/DWV procedures, the outside diameter of the weld (that is the outside diameter of the pipe plus twice the average height of the weld crown) shall be used.

Normally, Ug is 0.02 inch (0.51 millimeter) for material whose thickness is less than or equal to 2.0 inches(50.8 millimeters), but final acceptance of each radiograph should be based on the ability to see the prescribed IQI wire.
7.6. IQI (IMAGE QUALITY INDICATOR) IQIs shall be made of material that is radio graphically similar to the material being welded.IQI shall be used accordance with BS 3971.
Wire Type IQIs Wire type IQIs shall conform to the requirements of ASME Sec V Article 2, Para T276. The essential wire diameter to be used based on the thickness of the weld (Refer 15.2),
is shown in Table 276 of ASME Sec V Article 2 for wire type IQI. Smaller wire diameter IQIs than those specified above may be used, provided the
required radiographic sensitivity is obtained. The radiographic images of the wire type IQI identifying style number and ASTM set
letter shall appear clearly. The image of the essential wire diameter shall appear clearly across the entire area of
interest.
7.7. IQI LOCATION:
IQIs shall be placed in contact with the pipe across the weld and perpendicular to the weld length.
Wire Type IQIs
IQIs shall be located on the source side of the weld. Where this is not practical, the IQIs will be placed on the film side. In this case, a lead marker F will be placed adjacent to the penetrameter.
When a complete weld is radio graphed in a single exposure using a source inside the
piping (SWE/SWV), at least three IQIs placed across the weld and perpendicular to the weld length and spaced approximately equally around the circumference or one IQI per film whichever is greater shall be used.
For DWE/DWV exposure geometry one IQI shall be placed on the source side of the
pipe and adjacent to the weld so that its image is not superimposed on the weld image. For the DWE/SWV or the SWE/SWV procedures requiring multiple exposures for
complete inspection of the weld, and where the length of film to be interpreted is greater than 6 inches, two IQIs are placed across the weld and perpendicular to the weld length.

QQQ AAA TTT AAA RRR
The film side shall be used. Both IQI`s shall be within one inch from the end of the film to be interpreted with the thinnest wire facing outside.
When the film length to be interpreted is 6 inches or less, one IQI shall be placed on the
film side, perpendicular to the weld and located at one end of the length to be interpreted.
When a repaired weld is radio graphed, at least one IQI shall be placed adjacent to each
repaired area.
7.8. DIRECTION OF RADIATION The direction of central beam of the radiation should be centered on the area of interest whenever practical.
7.9. IDENTIFICATION OF IMAGES A zero datum shall be marked with indelible marker on the part surface to be inspected
not affecting the material under inspection at all. Images shall be clearly identified by the use of lead numbers, lead letters, markers, or other identification so that the proper weld and any discontinuities in it can be quickly and accurately located. For diameter less than 89 mm individual lead letter shall be placed for every exposure taken and shall related to the datum marked. The client may specify the identification procedure to be used.
Whenever more than one image is used to inspect a weld, identification markers shall
appear on each image, and adjacent images shall overlap.
The last reference marker on each end of the image shall appear on the appropriate adjacent images in a way that establishes that no part of the weld has been omitted. A minimum of 1 overlap on either side of the weld shall appear on the radiograph.
All film shall be clearly identified so that the part can be quickly and accurately located. The radiograph shall be traceable to the contract, component and etc. As a minimum, each film shall show:
'0 'Locations Top Dead Center Contract reference identification / Project No. Drawing / line number
Weld number, pipe , IQI image and wall thickness
Repair status i.e. R, R1 = Repair, R2 = 2nd Repair RW = Reweld. Date of exposure Welders identity number

How ever the identification numbers shall not obscure the area of interest. Scattered Radiation
A lead symbol B with minimum dimensions of (13mm) in height and 1/6( 4mm) in thickness, shall be attached to the back of each film holder. If a light image of the B appears on a darker background of the radiograph, protection from back scatter is insufficient and the radiograph shall be considered unacceptable, in such cases lead screens or suitable shielding can be used to absorb back scatter.
7.10. FILM DENSITY Density Limitation - except for small localized areas caused by irregular weld
configurations, the transmitted density in the area of interest of transparent based film shall not be less than 1.8 for x-ray and 2.0 in case of gamma ray. Maximum density shall be 4.0 in both the case.
Density Variation if the density of the radiograph anywhere through the area of interest
varies by more than minus 15% or plus 30% from the density adjacent to the designated wire of a wire IQI, within the minimum / maximum allowable density range specified in 13.1, then the additional IQI shall be used for each exceptional area or areas and the radiograph retaken.
Periodic verification and calibration of densitometer and step wedge film shall be done
as per ASME Sec V Article 2 Para T262.
7.11. IMAGE PROCESSING Film handling, Chemical mixing, storage should be as per ASME SE 999. Care shall be taken to ensure that films do not touch each other during processing. A minimum separation of 13mm shall be observed when films are being processed. The following bath temperature and dwell times are recommended FOR GUIDANCE ONLY:
Bath Temperature Dwell time Development 20 deg. C 5-8mins The following formula shall be used for IQI sensitivity percentage IQI Sensitivity Percentage = Thickness of the thinnest wire visible x 100
Specimen thickness
The penetrameter selection shall be based on the nominal wall thickness of the base material plus the reinforcement. Internal protrusions of single bevel welds, backing rings strips shall be disregarded in the selection of the required Penetrameter wire size. Reinforcement shall be based on estimated measurement and not actual measurement. In general the following shall apply:

Panoramic Single Wall-Single Image and Double Wall-Single Image Techniques
The required wire size and sensitivity calculation shall be based on the one wall thickness plus one reinforcement where such reinforcement is not ground off.
Double Wall-Double Image both elliptical and superimposed techniques. The required wire and sensitivity calculation shall be based on two wall thickness plus two reinforcements where such reinforcement is not ground off.
For welds without reinforcement the required wire size shall be based on the normal
single wall thickness or double wall thickness for double wall viewing (elliptical or superimposed techniques).
All radiographs shall have a satisfactory identification system.
8. ACCEPTANCE STANDARDS Acceptance and rejection criteria of weld defects shall be based on inspection/ material
class & category from table 341.3.2 in B31.3 (Refer Attachment 1) with following modifications:
Lack of fusion & Lack of Penetration is not permitted. Internal undercutting (applicable to double welded joints only) is not permitted.
9. DOCUMENTATION GAMA will prepare and document the radiographic technique details. As a minimum, the
following information will be provided.

10. STORAGE Once radiographs have been accepted, they shell be stored usually, in line (or) drawing number sets, or numerically in sets and consigned to manufactures original packing (film box) for reference and storage with concern to temperature and humidity. Film shall be kept under maximum of 26 deg unless and otherwise manufactures specification.
11. RADIOGRAPHIC TECHNIQUES In radiography the best possible flaw sensitivity is obtained when the thickness of metal which the radiation has to penetrate is kept to a minimum, therefore preference should always be given to a single wall method, if this is possible. Preference should always be given to a source inside / film outside method, if this is possible.(Refer Attachment 2) Technique No. Technique Thickness Range Diameter Range
