Non-destructive testing of welds - Ultrasonic testing -
Techniques, testing levels and assessment
1 Scope
This document specifies techniques for the manual ultrasonic testing of fusion-welded
joints in metallic materials of thickness not less than 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 the parent material are ferritic.
2 Normative references
The following referenced documents are indispensable for the application of this
document. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.
ISO 5577, Non-destructive testing - Ultrasonic testing - Vocabulary
NOTE. GB/T 12604.1-2020, Non-destructive testing -- Terminology -- Ultrasonic testing (ISO
5577.2017, MOD)
3 Terms and definitions
For the purposes of this document, the terms and definitions defined in ISO 5577 and
ISO 17635apply.
4 Symbols
The symbols in Table 1 apply.
5 General
The purpose of this document is to describe general techniques of ultrasonic weld
testing, using standard criteria, for the most commonly used welded joints at object
temperatures in the range 0°C to 60°C. The specific requirements of this document
cover the test equipment, preparation, performance of testing, and reporting. The
parameters specified, in particular those for the probes, are compatible with the
requirements of ISO 11666 and ISO 23279.
6 Information required prior to testing
The definitions 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 welded joint to be tested, additional written test procedures shall be
used, if required by specification.
7 Requirements for personnel and equipment
Any equipment used for testing in conjunction with this document shall comply with
the requirements of ISO 22232 (all parts).
The transducer size shall be chosen according to the ultrasonic path to be used and the
frequency.
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 defined 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 heat-affected zone is not known.
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.
