Non-destructive testing
Radiography is used to reveal primarily internal volumetric discontinuities. The
films are evaluated against the required quality level. Use of this method is limited by
the thickness of the weld, which should not exceed 50 mm.
Ultrasonic testing is most suitable for detecting internal plane discontinuities. It
requires a good test surface. The material should not be less than 8 mm thick for reliable
evaluation.
Magnetic particle testing is a surface testing method, used to reveal discontinuities
in or immediately below the surface of ferromagneticmaterials.
Liquid penetrant testing is also a surface testing method, and is used to reveal
discontinuities in the surface of non-porous materials.
Eddy current testing, or inductive testing, is used to reveal discontinuities on or
immediately below the surface of electrically conducting materials.
A common feature of all these test methods is that the test personnel must hold certif-
icates in accordance with EN 473. Testing must also be carried out in accordance with
approved test procedures.
