Standard Reference Radiographs for Examination of Aluminum Fusion Welds

Importancia y uso:

4.1 Personnel utilizing reference radiographs to this standard shall be qualified and authorized to perform radiographic interpretation in accordance with a nationally or internationally recognized NDT personnel qualification practice or standard such as ANSI/ASNT-CP-189, SNT-TC-1A, NAS 410, ISO 9712, or a similar document and certified by the employer or certifying agency, as applicable. The practice or standard used and its applicable revision shall be identified in the contractual agreement between the using parties. A certified Level III shall be available to assist with interpreting specifications and product requirements as applied to the reference radiographs (if the Level III is the radiographic interpreter, this may be the same person).

4.2 Use of these reference radiographs requires agreement between the using parties as to the acceptable level of each discontinuity type. Illustrations are provided for welds in 0.125 in. (3.2 mm) thick material and 0.50 in. (12.7 mm) thick material. These illustrations are intended to be representative of base material thicknesses up to 0.75 in. (19 mm). Use of these reference radiographs is not intended to be restricted to the specific energy level or the absolute thickness limits that are illustrated. These reference radiographs may be used, where there is no other applicable document, for other energy levels or thicknesses, or both, for which agreement has been reached between the purchaser and the manufacturer. Standard reference radiographs should be used in accordance with contractual specifications.
