The ultrasonic apparatus is to be fitted with a calibrated gain regulator with a maximum of 2 d B per step. The ultrasonic apparatus is to be equipped with a flat screen extending to the front of the apparatus so that a reference curve can be drawn directly on the screen.6.47.0 7.1 7.1 7.1.1 7.1.27.1.3Ultrasonic Examination ProcedureEPRO CONSTRUCTION QUALITY MANUAL7.1.4Page Date Revision Document No 5 / 25 01.03.2006 3 QM-QP-115The ultrasonic apparatus must be able to work with both combined and separated transmitter and receiver probe. Any equipment meeting the requirements of this section may be used for inspections. PROBES (TRANSDUCERS) Normal probes which are utilized, are to cover a frequency range of 1.0 –6.0 MHz. Typical values are 1.0 MHz, 2.0 MHz, 4.0 MHz and 6.0 MHz. The angle probes which are used, are to cover a frequency range of 1.0 –6.0 MHz. Typical values are 1.0 MHz, 2.0 MHz, 4.0 MHz and 6.0 MHz. Probes used shall not to cause more noise than that an echo with a height of %5 of full screen height can easily be distinguished from the normal level of noise. On surfaces with a small radius of curvature such as pipes with a small diameter. It may be necessary to adjust the probe shoe to attain sufficient contact between the material and the probe. COUPLANT A satisfactory couplant in either fluid or paste from is to be used to transfer the ultrasound from the probe to the material. Oil, grease, glycerin or paste is well suited to this purpose (A cellulose gum is particularly suitable as it can be removed with water after inspection completed). Couplant brand name or type used for examination shall be recorded on ultrasonic examination report. CALIBRATION BLOCKS FOR RANGE AND ANGLE CALIBRATION For the calibration of the ultrasound apparatus range scale and the angular determination of angle probes, an IIW calibration block or a V2 calibration block is to be used (DIN 54122). These are shown on Figure 1. Calibration blocks shall be retained in a safe place and prevented against corrosion or damage and controlled before use.7.1.5 7.2 7.2.17.2.27.2.37.2.47.3 7.3.17.4 7.4.1IIW (V1) CALIBRATION BLOCKV2 CALIBRATION BLOCK FIGURE 1. CALIBRATIONS BLOCKS OTHER AIDS7.5Ultrasonic Examination ProcedureEPRO CONSTRUCTION QUALITY MANUALPage Date Revision Document No 6 / 25 01.03.2006 3 QM-QP-1157.5.1“Ultrasound slide rules” or tables for determining the position of defects can be used. Similarly, a slide gauge for measuring the distance from the angle probe to the defect can be used as well as any other necessary measuring and marking equipment. INSPECTION TECHNIQUE Direct contact techniques with straight beam (normal incident longitudinal wave) and angle beam (shear waves) shall be used. SURFACE PREPARATION CONTACT SURFACE The contact surface is to be free of weld splatter and any other substance which may impede the free movement of the probe of hinder the transmission of ultrasound to the material. A light grinding of the surface may be necessary. The finish on the scanning surfaces of the calibration block shall be representative of the scanning surface finish on the component to be examined. WELD REINFORCEMENT Grinding of the weld reinforcement (cap pass) may be necessary if reflections received is suspicious and has the possibility of coming from the cap pass or from weld root. If accessible, the same applies to weld root. CALIBRATION RANGE CALIBRATION Normal probe range calibration is to be carried out with an IIW calibration block, a V2 calibration block or on a defect free known thickness calibration block of the same material to be inspected (see Figure 2). The range scale is to be selected such that there are always at least 2 back wall echoes (reflections) on the screen when one is calibrating. The first echo is put at 75% of full screen height (FSH) and with the test range selector and the zero point control of the ultrasonic apparatus one positions the echoes in such a way that the distance between them represents the thickness of the calibration block. Angle probe range calibration is to be carried out with an IIW calibration block or a V2 calibration block (see Figure 3). The probe index is to be determined by placing the probe as shown in Figure 3-a by maximizing the echo height received from the cylindrical surface of 100 mm radius (IIW) or 25 mm (V2). The echo height is to be adjusted to approximately 75% FSH. The probe index can now be measured between the scribe mark on the calibration block and probe front surface. For easy usage, index point may be marked on a stickers attached on the sides of the probe. The range scale is calibrated by placing the probes on IIW and receive echoes shown in Figure 3b or by placing V2 and receive echoes as shown in Figure 3-c. In these positions, always 2 echoes shall be visible on the screen. The echo heights shall be maximized, and the first echo shall be adjusted at ~75% FSH. With the aid of the test range selector and zero point control (depends on the UT instrument), the echoes are positioned so that they fall at 100 mm and 200 mm for the IIW block (see figure 3-b). The V2 block generates echoes at 25 mm and 100 mm or 50 mm and 125 mm (see figure 3-c).7.6 7.6.17.7 7.7.1 7.7.27.7.37.8 7.8.18.0 8.1 8.1.18.1.2Ultrasonic Examination ProcedureEPRO CONSTRUCTION QUALITY MANUALPage Date Revision Document No 7 / 25 01.03.2006 3 QM-QP-115FIGURE 2. NORMAL PROBE RANGE CALIBRATIONFIGURE 3 ANGLE PROBE RANGE CALIBRATION 8.2 8.2.1 PROBE ANGLE CHECK The probe angle is to be checked on the IIW block using the probe index found under 8.1.2, the echo from the circular Perspex reflector is maximized and adjusted at ~75% FSH. The probe angle shall be read from the index point on the probe and scribed angles on the calibration block (see figure 4).FIGURE 4. CHECKING THE PROBE ANGLEUltrasonic Examination ProcedureEPRO CONSTRUCTION QUALITY MANUALPage Date Revision Document No 8 / 25 01.03.2006 3 QM-QP-1158.3 8.3.1CORRECTION FOR DEVIATION IN SOUND VELOCITY Calibration as mentioned under 8.1 and 8.2 on IIW block or V2 block, is only valid for inspection of steel with approximately the same sound velocity of the standard calibration block used (about 5900 m/s compressional wave velocity, 3200 m/s transverse wave velocity). If working with steel qualities which have different sound velocities, the probe angle is to be corrected in accordance with the new velocity, or using a calibration block produced from the same material to be inspected. Any deviation in velocity may be investigated by calibrating the range scale on the IIW block for a straight beam probe and measure a known thickness of new material with the same calibration. SENSITIVITY CALIBRATION Calibration of the sensitivity is carried out by utilizing drilled holes as reference reflectors. Holes may be drilled in the actual production material or in reference blocks. Moving probe towards reflectors, a reference curve may be drawn on the screen ether by a crayon marker or by electronic circuit of the UT instrument as described in 8.5.8.48.5REFERENCE CURVE In order to compensate for attenuation and sound beam spread with increasing sound path a reference curve is to be constructed, which is drawn on to the screen of the ultra –sound apparatus, and which gives the echo height from the same reflector at varying distances between probe and reflector.8.5.1The reference curve is to be constructed by using a side drilled hole or surface notch as reference reflector. Side drilled hole or notch may be placed either directly in the production material or in a reference block made from the production material, or possibly from material with the same acoustic properties and surface condition of production material. The reference block shall have the same thickness (T) as the production material (see figure 5-b). When two or more thicknesses are involved, T shall be determined by the average thickness of the weld. Alternatively a calibration block thickness having greater base material thickness may be used provided the reference reflector size is based upon the average or smaller weld thickness. When the block thicknesses have ±25mm spans two weld thickness ranges, the block’s use shall be acceptable in those portion of each thickness range covered by 25 mm of the calibration block’s thickness. As an example, a calibration block with a thickness of 38 mm may be used for weld thicknesses of 13 mm to 64 mm. For examinations in materials where the examination surface diameter is greater than 508 mm (20”), a block of essentially the same curvature (see Figure 5-a), or alternatively, a flat basic calibration block, shall be used (see Figure 5-b). The basic calibration block shall be curved (see Figure 5-a) for materials with diameters 508 mm (20”) and less. Except where otherwise stated in this procedure, a single curved basic calibration block may be used to calibrate the examination on surfaces in the range of curvature from 0.9 to 1.5 times the basic calibration block diameter. For example, an 203 mm (8”) diameter curved block may be used to calibrate the examination on surfaces in the range of curvature from 183 mm to 305 mm (7.2” to 12”) diameter. The drilled hole shown in Figure 5-b is used as reference reflector and is to be drilled parallel to the examination surface of the reference block or the production material. The positions and the diameter of the drilled holes are given in Figure 5-b.8.5.28.5.38.5.48.5.58.5.6Ultrasonic Examination ProcedureEPRO CONSTRUCTION QUALITY MANUALPage Date Revision Document No 9 / 25 01.03.2006 3 QM-QP-115* Notches shall be located not closer than T or 25 mm (1”), whichever is greater, to any block edge or to other notches. GENERAL NOTES: a) b) c) d) e) The minimum calibration block length (L) shall be 200 mm (8”) or 8T, whichever is greater. For OD 100 mm (4”) or less, the minimum arc length shall be 270 deg. For OD greater than 100 mm (4”), the minimum arc length shall be 200 mm (8”) or 3T, whichever is greater. Notch depths shall be from 8% T minimum to 11% maximum. Notch widths shall be 6 mm (1/4”) maximum. Notch lengths shall be 25 mm (1”) minimum. Maximum notch width is not critical. Notches may be EDM or with end mills up to 6 mm (1/4”) in diameter. Notch lengths shall be sufficient to provide for calibration with a minimum 3 to 1 signal-to-noise-ratio.FIGURE 5-a CALIBRATION BLOCK FOR PIPEWeld thickness (t) mm ≤ 25 >25 to ≤ 50 >50 to ≤100 >100Calibration Block Thickness (T) mm 19 or t 38 or t 75 or t T ± 25Hole mm 2,5 3 5 **DiameterNotch Dimentions Depth=2% T Width=6 mm max.

GENERAL NOTES: a) b) c) d) e) f) Holes shall be drilled and reamed 38 mm deep minimum, especially parallel to the examination surface. For components equal to or less than 500 mm in diameter, calibration diameter shall meet the requirements of 8.5.5. two sets of calibration reflectors (holes, notches) oriented 90 deg from each other shall be used. Alternatively, two curved calibration blocks may be used. The tolerance for hole diameter shall be 0.8 mm. The tolerance of hole location through the calibration block thickness (i.e. distance from the examination surface) shall be 3 mm. All holes may be located on the same face of face (side) of the calibration block provided care is exercised to locate all the reflectors (holes, notches) to prevent one reflector from affecting the indication from other another reflector during calibration. Notches may also in the same plane as the inline holes. A sufficient number of holes shall be provided for both angle and staright beam calibratios at the ¼ T, ½ T and ¾ T depths. Minimum notch depth shall be 1.6% T and maximum notch depth shall be 2.2% T plus the thickness of claddind, if present. Maximum notch width is not critical. Notches may be EDM or with end mills up to 6 mm in diameter.FIGURE 5-b NON-PIPING CALIBRATION BLOCKSUltrasonic Examination ProcedureEPRO CONSTRUCTION QUALITY MANUALPage Date Revision Document No 10 / 25 01.03.2006 3 QM-QP-1158.5.6The drill hole as shown on figure 5b, is used as a reference reflector and is to be drilled parallel to the contact surface in the reference block or the production material. The positioning and the diameter of the drill hole are given in figure 5b. When constructing a reference curve with angle probe, the first point on the reference curve is to be determined by placing the probe in position A as shown on figure 6 a for plate thicknesses < 10 mm, as shown on Figure 6-b for plate thicknesses >25 mm. The sound path distance from point A to the reference reflector must not be less than 0.6 N, where N is the near field length for the relevant probe. The echo height from the drill hole is maximized and the gain control is adjusted to 75% FSH. This gain setting is called the primary gain and shall be recorded. Without changing the primary gain, the probe is positioned in half skip distances as shown on Figure 6-a, 6-b and 6-c. And the respective echo heights are marked on the screen. These points are connected by a smooth line with a length which covers the area to be inspected. This is the reference curve. When the reference curve has been set up, another curve, which is 20% of the reference curve, is to be drawn in, see figures 6-a, 6-b and 6-c.8.5.7(a)(b)(c)FIGURE 6 CONSTRUCTION OF REFERENCE CURVES. THE NUMBERS IN BRACKKETS ABOVE PROBES GIVE NUMBERS OF EIGHTS OF A FULL SKIP DISTANCEDate 01.03.2006 Revision 3CONSTRUCTION QUALITY MANUALDocument NoQM-QP-1158.5.8 If the reference curve by excessive sound paths falls below 25 % of full screen height the gain in this area is to be increased in the following way.The probe is placed in position B (alternatively C) as shown on Figure 7 and the echo height is maximized and adjusted at 75% FSH. The new primary gain is noted. Without altering this, the probe is moved to position C (alternatively D) and a new reference curve is set up on the screen of the ultrasonic apparatus and its 20 % curve to be used. The primary gain will now be greater than for the original reference curve and applies only for inspection in this area.FIGURE 7. INCREASING GAIN FOR EXCESSIVE SOUND PATH8.5.9 For inspecting weld joints less than 50 mm with a straight beam probe, a reference curve defined below shall be constructed:The production material or reference block with reference reflector described in 8.5.1 through 8.5.6, the probe is placed position A of Figure 8-a. The echo height is maximized to 50% FSH. The primary gain is noted. The reference curve is drawn as a horizontal line on the screen.8.5.10 For inspecting weld joints greater than 50 mm with a straight beam probe, a reference curve defined below shall be constructed:The production material or the reference block and the reference reflectors described in 8.5.1 through 8.5.6, the probe is placed over the drilled hole position A of Figure 8-b, the echo height is maximized to 50 % FSH. This gain setting is the primary gain and is noted. Without altering this, the probe is moved to position B, the echo height is marked on the screen. The two points are connected with a straight line, extending until it covers the interested area. This is the reference curve.Date 01.03.2006 Revision 3CONSTRUCTION QUALITY MANUALDocument NoQM-QP-115abFIGURE 8 SENSITIVITY CALIBRATIONS FOR NORMAL PROBES8.5.11As shown on Figure 6-a, Figure 6-b and 6 c, the area of the reference curve between zero and the first point on the reference curve (A) is not used for defect evaluation. This zone is the near zone of the probe and in this zone it is very difficult to assess the discontinuity size. There is, however, nothing prevents using this zone for locating discontinuities. For example, when inspecting the root area of butt welds in thin plates with a face and root reinforcement; it is often very difficult to find incomplete penetration if this zone not used. Otherwise, the reinforcement shall be flush ground to find this kind of discontinuities but it is impossible to do so for long pipelines. When discontinuities found in the near field area, the defect evaluation shall be performed within the reference curve, i.e. the sound path to the defect is increased so that the echo from the defect remains within the reference curve area.8.5.12If the ultrasonic instrument has electronic distance/amplitude correction, this can be used for angle probes and normal probes. The echo height from the drilled hole in the production material or reference block is then to be adjusted to 75% FSH over the whole inspection range. The reference curve will thus be a horizontal line. The gain setting is noted as primary gain.8.5.13 Any possible differences in attenuation and surface condition between the reference block and the production material during inspection with angle probes shall be checked in the following way:Use two angle probes of the same type of probes used for inspection. The probes shall be placed on the production material as shown in Figure 9. One of the probes works as transmitter, whilst the other acts as receiver. The first echo is maximized and put at a certain height on the screen, for example 80% FSH. The gain setting is noted. Without altering this gain setting the probes shall be moved to the reference block and the echo height is noted. Any difference in echo heights between the two checks shall be measured in dB with the aid of gain control. If any difference found, correction shall be done as follows and the final value is called “corrected primary gain:• When the echo height from the production material is less than the echo height from thereference block, the difference, in dB, is to be added to the primary gain.Date 01.03.2006 Revision 3CONSTRUCTION QUALITY MANUALDocument NoQM-QP-115•When the echo height from the production material is greater than that from the reference block, the difference, in dB, is to be subtracted from the primary gain.FIGURE 9 ATTENUATION AND TRANSFER CORRECTION8.6 PERIODIC INSPECTION OF ULTRASONIC INSTRUMENT AND PROBESIn order to ensure at any time that the ultrasonic equipment is in order, the operator shall check the equipment during ultrasonic inspection.8.6.1 ULTRASONIC INSTRUMENT• Sensitivity calibration of equipment shall always be carried out prior to thecommencement of operations, • Every two hours,• Any time the instrument is switched OFF and ON,• Any time a part of instrument replaced (Cable, Probe etc.),8.6.2 Any time there is doubt about instrument calibration, the following checks should be performed:Date 01.03.2006 Revision 3CONSTRUCTION QUALITY MANUALDocument NoQM-QP-1158.6.2.1 Check the range with the aid of the IIW block or the V2 block.8.6.2.2 Check the corrected primary gain as defined in 8.5.13.8.6.2.3During the verification checks, any deviation found more than 10 % or that the reference amplitude has reduced by more than 20% or 2 dB, all welds inspected after last check shall be re-inspected.8.6.3 PROBES8.6.3.1 The probes shall be inspected frequently, before and after ultrasonic inspection. Angle probesused on rough surfaces shall be inspected ever two hours.8.6.3.2 Inspect the angle probe shoe for possible wear. If wear has caused an angle deviation ≥ 2° fromthe nominal value, the probe shall be changed. When changing a probe, the whole range calibration described in 8.1.2 shall be repeated.8.6.3.3 Normal probes shall be inspected by placing them on the production material or reference block,and at least three back wall echoes shall be visible when the first bottom echo is adjusted to 100 % FSH. The protective cover shall also be inspected and if it is worn out, it must be changed and the range calibration defined in 8.1.1 shall be repeated.9.0 TECHNIQUEThis procedure covers inspection of base metal by normal beam probe and inspection of weld joints by normal and angle beam probes.9.1 INFORMATION REQUIRED BEFORE INSPECTIONBefore inspection starts, the following information shall be provided to the UT Operator: • Material type • Bevel design • Welding procedure • Details of repairs done • Other factors effects the metallurgical structure of the material to be inspected (e.g. heattreatment).9.2 BASE METAL INSPECTIONBase metal inspection with a normal beam probe from both sides of the weld shall be performed to see if laminations, large variations in sound velocity and attenuation and thickness variations in the base material is present.9.2.1 Inspection of the base metal shall be carried out with a normal beam probe with a frequencybetween 2 and 6 MHz. The highest frequency which ensures good sound penetration shall be selected (see 7.2.1). After range calibration 8.1.1 and sensitivity calibrations 8.5.9 and 8.5.10, base metal on both sides of the weld joint which will transfer angle beam ultra-sound for inspection shall be inspected. Discontinuities in the base metal shall be assessed and corrected if necessary, to ensure the weld joint can inspected with angle beam probe without any negative affect. The extent of the discontinuity shall be plotted by half-value or 6 dB technique (see 9.3.5) 9.3 INSPECTION OF WELD JOINTSInspection of weld joints shall be performed to find possible:• Discontinuities in the base metal• Discontinuities in the weld metal and heat-affected zone • Lack of fusion between weld and base metal.Date 01.03.2006 Revision 3CONSTRUCTION QUALITY MANUALDocument NoQM-QP-1159.3.1A favorable probe angle in relation to the plate thickness for volumetric weld defects is given in Table I and Table II for weld joint inspections with and without reinforcement.Table I Weld Without ReinforcementPLATE THICKNESS, MM FAVOURABLE PROBE ANGLE5-15 70° 15 – 30 45°, 60°, 70° 30 – 60 45°, 60°, (70°) OVER 60 45°, 60°,Table II Weld With ReinforcementPLATE THICKNESS, MM FAVOURABLE PROBE ANGLE5-20 70° 20– 40 45°, 60°, 70° OVER– 40 45°, 60°, (70°)9.3.2When a weld joint inspected for lack of fusion, a favorable angle is the angle which gives incident sound normal to lack-of-fusion (~90 deg to the expected discontinuity orientation) (see Figure 10). The optimum angle for a V-grove joint design is given by the grove geometry and can be calculated as shown in Figure 10. If the calculated angle does not agree with any standard probe angle, the nearest larger probe angle is to be selected.FIGURE 10 DETECTION OF LACK OF FUSION9.3.3 The frequency shall be within the range of 1 –6 MHz, and shall selected as high as possible givingsatisfactory sound transmission.9.3.4 The gain to be used in the defect evaluation is the corrected primary gain. When inspecting fordiscontinuities, the gain shall be increased by 6 dB to increase the sensitivity for discontinuities with difficult orientation. Added 6 dB shall be reduced for defect evaluation.9.3.5 The extent of discontinuities for longitudinal direction shall be determined by the half-value or 6 dBmethod. This method can be used for both normal and angle beam probes (see Figure 11). The extent of the discontinuity shall be determined by finding maximum echo height in the middle of the discontinuity and 6 dB gain is added to this height. Subsequently, the probe moved towards the edge。
