Assessing Radiographs of SAW Stainless-Steels Welds for Mottled Indications
Presentation Description
When radiographing an austenitic stainless-steel weld with an appreciable weld deposit size, selecting a low radiographic kilovoltage (keV) can contribute to producing a radiographic indication that is not an imperfection or flaw. The combination of the above can create a mottled radiographic indication that radiographers may incorrectly identify as incomplete fusion or incomplete penetration. This presentation addresses the contributors to this condition; radiographically and metallurgically.
