The positional encoder which is placed on scanner shall be calibrated by moving a minimum
distance of 20inch (500mm) and displayed distance being ±1% of the actual distance moved.
9.2
Confirmation
A calibration check shall be performed at intervals not to exceed one month or prior to first use
thereafter.
10.0 EXAMINATION AREA TO BE COVERED
10.1 The PAUT examination area shall cover the ID and OD volume of weld, The examination area
shall include the volume of the weld, plus the lesser of 25mm (1.0 in.) or t of adjacent base
metal. Alternatively, the examination volume may be reduced to include the actual heat
affected zone (HAZ) plus 6mm (0.25 in.) of base material beyond the heat affected zone on
each side of the weld, provided the extent of the weld HAZ is measured and documented.
10.2 A scan plan for each thickness and bevel angle shall be made to ensure weld coverage and
additional area as per clause 10.1. The scan plan shall contain all the beam angles used in
virtual probe aperture (VPA) to cover weld examination area. All the scan plans shall be
documented as Appendix to this procedure.
11.0 CALIBRATION PROCEDURE
Calibration shall be performed from the surface of the calibration block which corresponds to the
component surface to be examined. System calibration shall include the complete ultrasonic
examination system. Screen distance calibration shall be at least 1½ “vee paths”
(also known as skip) for the minimum angle that will be used during the examination, unless
otherwise
specified.
During
scanning,
only
the
gain
may
be
adjusted
from
the calibrated reference dB. Adjustment of other controls requires recalibration.
Focal Law: Focal law is a computer-controlled program of firing sequence of the probe elements
used in Virtual probe aperture selected for scan plan. The focal law shall be the same for calibration
and examination.
11.1 Velocity Calibration
The purpose of ultrasonic calibration is to measure the real velocity of ultrasonic waves in the
material to be inspected. The calibration block used must have two known reflectors and be
made in the same material as the part to be inspected. In order to calibrate the velocity, place the
probe on a calibration block and select appropriate echo type from set Radius/Depth/Thickness
1 and 2 steps. In the radius /Depth/Thickness 1, enter a known radius/depth/ thickness that
corresponds to the first signal on the A Scan time base, also repeat the same in the radius

/Depth/Thickness 2. Choose an angle/VPA parameter normally in the middle of the scan. The
range shall set such that two echoes shall in the visible range of the A scan. Get position while
setting the gate from the first signal, repeat the same for the second signal. Choose Accept if the
calculated velocity shown in the material velocity parameter is reasonable for the calibration
block material or choose Restart to repeat the procedure.
11.2 Wedge Delay Calibration
The wedge delay calibration shall be carried out for both linear scan as well as sartorial scan. The
wedge delay calibration shall be carried out in true depth mode or sound path mode and done
with a known reflector depth or radius. Peak up this signal from the calibration reflector and
scan the phased array probe backwards through all the different angles or focal laws. Scan
forward over the calibration reflector through all the refracted angles of focal laws. When the
signal for all angles and focal laws lies within the threshold, the Omniscan system shall adjust all
the focal laws/angles to display the reflector’s true depth.
12.2 Wedge Delay Calibration
11.3 Sensitivity Calibration:
The Omniscan® shall be calibrated for wedge delay and sensitivity. The sensitivity calibration
shall provide the required gain adjustments for each refracted angle and sound path used. Select
a calibration reflector, which is approximately one-half the thickness of the component to be
examined, or Ø 1.5mm SDH on IIW V1 block. Peak up this signal from the calibration reflector
or radius and scan the phased array probe backwards through all the different angles of focal
laws. The Omniscan system shall calculate the required gain needed at each focal law to
adjust the amount of gain required to obtain the sensitivity.

11.3 Sensitivity Calibration
11.4 Time Corrected Gain (TCG) Calibration:
Time corrected gain calibration shall be used to compensate for attenuation in the material at the
sound paths used during calibration and examination. To obtain the TCG calibration peak the
signal from the ID notch at half skip distance and adjust the gain to obtain 80% of
amplitude from the reflector. Place the phased array probe perpendicular to the notch axis.
Move the phased array probe forward and backward to equal the amplitude for all the focal laws
and angles and plot the first point. Move the probe to the OD notch o and obtain the second
point. OmniScan users the gain compensation required due to attenuation in the sound travel
and adjust the gain for all focal laws/angles.
Once all the points are picked the TCG can be accepted. TCG calibration has to be carried out
for all scan plans in a multi group option while using phased array probe.
The examination system calibration shall be stored in the OmniScan System with electronic
memory, on an external chip or data storage device. This calibration may be used at a later
date provided that date provided that the system calibration is verified prior to the
examination.
12.0 IDENTIFICATION OF WELD EXAMINATION AREA
12.1 Weld Location: Weld location and identification such as part number, seam number shall be
recorded.
12.2 Marking: If welds are to be permanently marked, hard number punch/ vibroetching can be
used. Marking after final stress relief of the component shall not be deeper than 1.2mm.
12.3 Reference System: Each weld shall be located and the reference point shall be marked by 0 at
Datum.

13.0 SCANNING
13.1 Angle Beam Examination (PAUT Technique): Scanning for Reflectors Parallel to the Weld
Seam:
The specifics of the examination volume, weld definition and location shall be identified in the
scan plan. The examination volume shall cover shall be as per clause 10.1.
The scan plan shall demonstrate by plotting or with using a simulator the appropriate
examination angle for the weld preparation bevel angles that will be used during the
examination. This scan plan shall be documented to show that the examination volume was
examined. This scan plan shall be a part of the final examination.
Note: Based on the real weld configuration, modification shall be done on the scan plan or the
index offset has to be changed such that the required coverage has complied.
OmniScan system has the capability of using multiple-group settings to establish sector
scans and E-scans for the appropriate angles to ensure complete coverage of the weld and
heat affected zone.
Scanning shall be performed using a line scan technique.
Line (or Linear) scanning is defined as a single pass scan of the search unit parallel to the weld
axis at a fixed stand off distance.
Each line scan shall be parallel to the weld using a Sectorial scan (S-scan).
Appropriate refracted angle as accepted by ASME will define the position of the arrays and
hence angles. These should be detailed in the ultrasonic scan plan.
Angular sweep incremental change shall be a maximum of 1º or sufficient to assure 50% beam
overlap.
Scans shall be parallel to the weld at 90º /270º scan axes and the multiple groups scanning shall
involve both the above directions for complete coverage of the weld from OD as shown in
attached scan plan.
Scanning shall be performed towards clock wise direction from the marking.
Minimum scanning overlap of 50mm shall be done between successive scanning’s.
Scanning sensitivity level for examination shall not be less than that qualified for TCG. When
multiple linear scans are required to cover the volume of weld and base metal over lap between
adjacent linear scans shall be a minimum of 10% of the beam width for S-Scans.
13.2 Rate of Search unit movement:

The scanning speed shall be such that data drop out is less than 2 data lines per inch (25mm) of
the linear scan length and that there is no adjacent data line skips or shall not exceed that
qualified.
13.3 Pulse repetition rate:
The pulse repetition rate is small enough to assure that a signal from a reflector located at the
maximum distance in the examination volume will arrive back at the search unit before the
next pulse is placed on transducer.
13.4 Reflectors transverse to the weld seam.
A manual angle beam examination shall be performed for the reflectors transverse to the weld
axis as described below.
Scanning with weld reinforcement: If the weld cap is not machined or ground flat,
The examination shall be performed from the base material on the both sides of the weld cap.
While scanning parallel to the weld axis, the angle beam shall be directed from 0º to 60º with
respect to the weld axis in both axial directions, with the angle beam passing through the
required examination volume.
Scanning without weld reinforcement:
If the weld cap is machined or ground flat, the
examination shall be performed on the weld .While scanning the angle beam shall be directed
essentially parallel to the weld axis in both axial direction. The search unit shall be
manipulated so that the angle beam passes through the required examination volume.
13.5 Restricted Access Welds:
The welds that cannot be fully examined from two directions using angle beam technique shall
also be examined if possible with straight beam technique upto the full extent without
recording.
14.0 DATA RECORDING
14.1 Recording
A-Scan data shall be recorded for the area of interest in an unprocessed form with no
thresholding and recording increments of a maximum of 1mm for material thickness
upto75mm and 2mm for material thickness above 75mm.
14.2 Data Recording Media
All production test scans will be stored in the Phased Array computer’s hard drive; the same
shall be copied to external hard drive.

15.0 DATA ANALYSIS
a)
Reflectors exceeding the limits below shall be investigated to determine whether the indication
originates from a flaw or is a geometric indication in accordance with 15(b) below.
i)
For amplitude based techniques, the location, amplitude, and extent of all reflectors that
produce a response greater than 20% of the reference level shall be investigated.
b)
Ultrasonic indications of geometric and/or metallurgical origin shall be classified as specified
in ASME Section V, as follows
The following steps shall be taken to classify an indication as geometric:
(i)
Interpret the area containing the reflector in accordance with the applicable examination
procedure.
(ii)
Plot and verify the reflector coordinates. Prepare across-sectional sketch showing the reflector
position and surface discontinuities such as root and counter bore.
(iii) Review fabrication or weld preparation drawings. Other ultrasonic techniques or
nondestructive examination methods may be helpful in determining a reflector’s true position,
size, and orientation.
c)
Alternatively, other techniques or NDE methods may be used to classify an indication as
geometric (e.g., alternative beam angles, radiography). The method employed is for
information only to classify the indication as geometric.
16.0 FLAW EVALUATION & SIZING
a)
The dimension of the flaw(s) shall be determined by the rectangle that fully contains the area
of the flaw(s). (Refer to Fig. 2)
i)
The length, ℓ, of the flaw shall be drawn parallel to the inside pressure retaining surface
of the component.
ii)
The height, a, of the flaw shall be drawn normal to the inside pressure retaining surface
of the component.
iii)
The flaw shall be characterized as a surface or subsurface flaw, as shown in Figure 2.
Surface flaws - Unless the UT data confirms that a flaw is not surface connected it shall
be considered a surface connected flaw and alternatively, other techniques or NDE
methods may be used to classify an indication as geometric
iv)
A subsurface indication shall be considered as a surface flaw if the separation (S in
Figure 2) of the indication from the nearest surface of the component is equal to or less

than half the through wall dimension (a in Figure 2, sketch [b]) of the subsurface
indication.
b) Flaw Sizing
b.1) Flaw Length
The flaw length shall be performed by using the 6dB Drop method.
b.2) Flaw Height
Flaw height normal to the surface can be measured from the B-, E-, or S-scan images using
amplitude drop or tip diffraction techniques.
(a) Using amplitude drop techniques, the horizontal cursors are placed on the displayed flaws
upper and lower extents. The below figure shows an example of cursors used for height
sizing with the amplitude drop technique.
(b) Using tip diffraction techniques, the horizontal cursors are placed on the upper and lower
tip signals of the displayed flaw. Below figure shows an example of cursors used for height
sizing with the tip diffraction technique.
