Socket welds and fillet welds are not suitable for radiographic inspection; instead, they should be assessed using dye penetrant or magnetic particle testing methods, as specified in AIGA 033-14. Inspections of welded assemblies shall be conducted in accordance with the standards established in ISO 3452-1 and ISO 17638. Such inspections are always to be performed after the completion of any necessary hydrostatic testing. It is important to note that this requirement may lead the Contractor to conduct surface examinations prior to hydrostatic testing to ensure compliance with the construction code or the harmonized product standard. A marking plan for these areas should be maintained in the piping documentation, as referenced in S-SG-TU-0615.
