Course Overview
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.
Upon Completion, Learners Will Have Covered:
- Compare the differences between x-ray and gamma ray radiography on the same subject.
- Analyze the impact of changing mA and kV settings when radiographing stainless steel welds.
- Explain the metallurgical and chemical contributors that affect radiographic quality in stainless steel (SAW) welds.
