Question 1986 Deck Safety

The correct answer is D) Radiographic. Radiographic testing is the most effective method for detecting internal flaws in welds. This non-destructive testing technique uses X-rays or gamma rays to penetrate the weld and create an image that can reveal any internal defects, such as cracks, voids, or inclusions. Radiographic testing is the only option listed that can reliably identify flaws within the weld material itself, rather than just on the surface. The other options, such as dye penetrant (A) and magnetic particle (C) testing, are better suited for detecting surface-breaking flaws. Chemical reaction (B) is not a common weld testing method. For the purposes of identifying internal weld defects, radiographic testing is the appropriate choice.
