ISO 17640:2017(E)

Non-destructive testing of welds — Ultrasonic testing — Techniques, testing levels, and assessment 1 Scope This document speciies techniques for the manual ultrasonic testing of fusion-welded joints in metallic materials of thickness ≥8 mm which exhibit low ultrasonic attenuation (especially that due to scatter) at object temperatures from 0 °C to 60 °C. It is primarily intended for use on full penetration welded joints where both the welded and parent material are ferritic. Where material-dependent ultrasonic values are speciied in this document, they are based on steels having an ultrasonic sound velocity of (5 920 ± 50) m/s for longitudinal waves and (3 255 ± 30) m/s for transverse waves. This document speciies four testing levels, each corresponding to a different probability of detection of imperfections. Guidance on the selection of testing levels A, B, and C is given in Annex A. This document speciies that the requirements of testing level D, which is intended for special applications, be in accordance with general requirements. Testing level D can only be used when deined by speciication. This includes tests of metals other than ferritic steel, test s on partial penetration welds, tests with automated equipment, and tests at object temperatures outside the range 0 °C to 60 °C. This document can be used for the assessment of discontinuities, for acceptance purposes, by either of the following techniques: a)

evaluation based primarily on length and echo amplitude of the discontinuit y;

b) evaluation based on characterization and sizing of the discontinuity by probe movement techniques.

m) procedures for correct ive actions when unacceptable discontinuities are revealed.

6.3

Written test procedure

The deinitions and requirements in this document normally satisfy the need for a written test procedure. Where this is not the case, or where the techniques described in this document are not applicable to the weld joint to be tested, additional written test procedures shall be used, if required by speciication.

7 Requirements for personnel and equipment 7.1

Personnel qualiications

Personnel performing testing in accordance with this document shall be qualiied to an appropriate level in ultrasonic testing in accordance with ISO 9712 or equivalent in the relevant industrial sector. In addition to a general knowledge of ultrasonic weld testing, personnel shall also be familiar with testing problems speciically associated wit h the t ype of welded joints to be tested.

7.2

Test equipment

Any equipment used for testing in conjunction with this document shall comply with the requirements of EN 12668 (all parts).

7.3 7.3.1

Probe parameters Test frequency

The frequency shall be within the range 2 MHz to 5 MHz and shall be selected to consider the properties of the test object and to comply with the speciied acceptance levels, for example, of ISO 11666. Higher frequencies may be used to improve range resolution if this is necessary when using standards for acceptance levels based on characterization of discontinuities, e.g. ISO 23279. Lower frequencies may be used for testing at long sound paths and/or when the material shows high attenuation. 7.3.2

Angles of incidence

When testing is carried out with transverse waves and techniques that require the ultrasonic beam to be relected from an opposite surface, care shall be taken to ensure that the angle between the beam and the normal to the opposite relecting surface is between 35° and 70°. Where more than one beam angle is used, at least one of the angle-beam probes used shall conform to this requirement. One of the beam angles used shall ensure that the weld fusion faces are tested at, or as near as possible to, normal incidence. When the use of two or more beam angles is speciied, the difference between the nominal beam angles shall be 10° or greater. Angles of incidence at the probe and opposite relecting surface, when curved, may be determined by drawing a sectional view of the weld or in accordance with the techniques given in ISO 16811. Where angles of incidence cannot be determined as speciied by this document, the test report shall contain

4



ISO 17640:2017(E)

a comprehensive description of the scans used and the extent of any incomplete coverage caused, together with an explanation of the dificulties encountered. 7.3.3

Element size

The element size shall be chosen according to the ultrasonic path to be used and the frequency. The smaller the element, the smaller the length and width of the near ield, and the larger the beam spread in the far ield at a given frequency. Small probes having 6 mm to 12 mm diameter elements (or rectangular elements of equivalent area) are therefore most useful when working at short sound paths. For longer sound paths, i.e. greater than 100 mm for single straight-beam probes and greater than 200 mm for angle-beam probes, an element size of 12 mm to 24 mm is more suitable. 7.3.4

Adaptation of probes to curved scanning surfaces

The gap, g, between test surface and bottom of the probe shall not be greater than 0,5 mm. For lat probes on cylindrical or spherical surfaces, this requirement can be checked with Formula (1): g = a2/4D

(1)

where a

is the dimension of the probe in the direction of curvature, in mm;

D

is the diameter of the test object, in mm.

If a value for g larger than 0,5 mm results from the formula, the probe shall be adapted to the surface and the sensitivity and range shall be set accordingly. For spherical or complex shaped surfaces, Formula (1) shall be applied in both length and width direction of the probe (possible differences in curvature and/or probe dimensions). 7.3.5

Coupling media

The coupling media shall be in accordance with ISO 16810. The coupling medium used for range and sensitivity setting and for the test shall be the same.

8

Testing volume

The testing volume (see Figure 2) is deined as the zone which includes weld and parent material and the width of the heat-affected zone on each side of the weld or at least 10 mm if the width of the heataffected zone is not known. In all cases, scanning shall cover the whole testing volume. If individual sections of this volume cannot be covered in at least one scanning direction, or if the angles of incidence with the opposite surface do not meet the requirements of 7.3.2, alternative or supplementary ultrasonic techniques or other non-destructive techniques shall be agreed upon. This may, in some cases, require removal of the weld reinforcement. Supplementary techniques can require testing using dual-element angle-beam probes, creeping wave probes, further ultrasonic techniques or any other suitable method, e.g. liquid penetrant, magnetic particle, radiographic testing. In selecting alternative or supplementary techniques, due consideration should be given to the type of weld and probable orientation of any imperfections to be detected.



5

ISO 17640:2017(E)

9 Preparation of scanning surfaces Scanning surfaces shall be wide enough to permit the testing volume (see Figure 2) to be fully covered. Alternatively, the width of the scanning surfaces may be smaller if equivalent coverage of the testing volume can be achieved by scanning from both the upper and the lower surface of the joint. Scanning surfaces shall be even and free from foreign matter likely to interfere with probe coupling (e.g. rust, loose scale, weld spatter, notches, grooves). Waviness of the test surface shall not result in a gap between the probe and test surfaces greater than 0,5 mm. These requirements shall be ensured by dressing, if necessary. Local variations in surface contour, e.g. along the edge of the weld, which result in a gap beneath the probe of up to 1 mm, can only be permitted if at least one additional beam angle is employed from the affected side at the weld. This additional scanning is necessary to compensate for the reduced weld coverage that will occur with a gap of this dimension. Scanning surfaces and surfaces from which the sound beam is relected shall allow undisturbed coupling and relection.

10 Parent metal testing The parent metal, in the scanning zone area (see Figure 2), shall be tested with straight-beam probes prior to or after welding, unless it can be demonstrated (e.g. by previous testing during the fabrication process) that the angle-beam testing of the weld is not inluenced by the presence of the imperfections or high attenuation. Where imperfections are found, their inluence on the proposed angle-beam testing shall be assessed and, if necessary, the techniques adjusted correspondingly. When satisfactory coverage by ultrasonic testing is seriously affected, other test techniques (e.g. radiographic testing) shall be considered.

11 Range and sensitivity setting 11.1 General Setting of range and sensitivity shall be carried out prior to each testing in accordance with this document and ISO 16811, taking the inluence of temperature into account. The temperature difference during range and sensitivity setting a nd during the test shall be within ±15 °C. Checks to conirm these settings shall be performed at least every 4 h and upon completion of the testing. Checks shall also be carried out whenever a system parameter is changed or changes in the equivalent settings are suspected. If deviations greater than 2 dB, resp. 1 % of range, are found during these checks, the corrections given in Table 2 shall be carried out.

11.2 Reference for sensitivity setting One of the following techniques for setting the reference shall be used. The use of these techniques may not result in equal test results. Different testing results may occur by usage of different techniques for sensitivity set ting. — Technique 1: the reference is a distance-amplitude curve (DAC) for side-drilled holes of diameter 3 mm. — Technique 2: the references for transverse and longitudinal waves using the distance-gain-size (DGS) system based on the diameter of the disk-shaped relectors (DDSR) are given in Tables 3 and 4, respectively. — Technique 3: the reference notch shall be 1 mm wide, rectangular, with a depth of 1 mm. This technique applies only for the thickness range 8 mm ≤ t < 15 mm and only for beam angles ≥70°. — Technique 4: for the tandem technique, the reference is a disk-shaped relector (lat-bottom hole) of 6 mm diameter (for all thicknesses), perpendicular to the scanning surface. This technique is applicable only for beam angle 45° and thickness t ≥ 40 mm. The length of the side-drilled holes and notches shall be greater than the width of the sound beam at −20 dB amplitude.

11.3 Evaluation levels All indications equal to or exceeding the following levels shall be evaluated. The evaluation levels for techniques 1 t o 4 are given in ISO 11666:2010, Table A.1.

11.4 Transfer correction When separate blocks are used for establishing reference levels, a measurement shall be made of the transfer differences, between test object and block, at a representative number of locations. Suitable techniques are described in ISO 16811. If the differences are less than or equal to 2 dB, correction is not required. If the dif ferences are greater than 2 dB but smaller than or equal to 12 dB, they shall be compensated for. If transfer losses exceed 12 dB, the reason shall be considered and further preparation of the scanning surfaces shall be carried out, if applicable. When there are no apparent reasons for high correction values, the attenuation, at various locations on the test object, shall be measured and, where it is found to vary signiicantly, corrective actions shall be considered.

11.5 Signal-to-noise ratio During testing of the weld, the noise level, excluding spurious surface indications, shall remain at least 12 dB below the evaluation level. This requirement may be relaxed subject to speciication.

12 Testing levels Quality requirements for welded joints are mainly associated with the material, welding process and service conditions. To accommodate all of these requirements, this document speciies four testing levels (A, B, C, and D). From testing level A to testing level C, an increasing probability of detection is achieved by an increasing testing coverage, e.g. number of scans, surface dressing. Testing level D may be agreed for special application using a written procedure which shall take into account the general requirements of this document. In general, the testing levels are related to quality levels (e.g. ISO 5817). The appropriate testing level may be speciied by standards for testing of welds (e.g. ISO 17635), product standards or other documents. When ISO 17635 is speciied, the recommended testing levels are as given in Table 5.

Special application

Speciic requirements for testing levels A to C are given for various types of joints in Annex A. The joint types shown are ideal examples only; where actual weld conditions or accessibility do not conform exactly to those shown, the testing technique shall be modiied to satisfy the general requirements of this document and the speciic testing level required. For these cases, a written test procedure shall be prepared.

13 Testing techniques 13.1 General Ultrasonic testing shall be performed in accordance with ISO 16810 with the addition of the speciications in 13.2 to 13.5.

13.2 Manual scan path During angle-beam scanning (as illustrated in Figure 2), a slight swivelling movement up to an angle of approximately 10° on either side of the nominal beam direction shall be applied to the probe.

13.3 Testing for imperfections perpendicular to the testing surface Subsurface planar imperfections perpendicular to the testing surface are dificult to detect with single angle-beam techniques. For such imperfections, speciic testing techniques should be considered, particularly for welds in thicker materials. Use of these testing techniques shall be deined by speciication.

13.4 Location of discontinuities The location of discontinuities shall be deined by reference to a coordinate system, e.g. as shown in Figure 1. A point on the testing surface shall be selected as the origin for these measurements. Where testing is carried out from more than one surface, reference points shall be established on each surface. In this case, care shall be taken to establish a positional relationship between all reference points used, so that the absolute location of all discontinuities can be established from any nominated reference point. In the case of circumferential welds, this can require the establishment of the inner and outer reference points prior to assembly for welding.

13.5 Evaluation of indications 13.5.1 General All relevant indications above the evaluation level shall be assessed in accordance with 13.5.2 to 13.5.4. 13.5.2 Maximum echo amplitude The echo amplitude shall be maximized by probe movement and recorded in relation to the reference level. 10



ISO 17640:2017(E)

13.5.3 Discontinuity length The length of a discontinuity, in either the longitudinal or transverse direction (l x , l y ), shall, where possible, be determined using the technique speciied in the acceptance levels standard, unless otherwise agreed. 13.5.4 Discontinuity height The height of a discontinuity shall only be determined if required by speciication. 13.5.5 Characterization of discontinuities If speciied, discontinuities shall be characterized in accordance with ISO 23279.

14 Test report The test report shall include at least the following information: a)

an identiication of the object under test: 1) the material and product form; 2) the dimensions; 3) the location of tested weld/welded joint, sketch showing geometrical coniguration (if necessary); 4) a reference to the welding procedure, speciication and heat treatment; 5) the state of manufacture; 6) the surface conditions; 7) the temperature of the test object;

b) the contract requirements, e.g. speciications, guidelines, special agreements, etc.; c)
