Internal weld defects can be detected with radiographic testing equipment.

Internal weld defects can be detected with radiographic testing equipment.

• A. Sometimes
• B. Not Sure
• C. False
• D. True

Answer: (D)

Radiographic testing uses penetrating radiation to image the interior of a weld and surrounding metal. Internal defects such as porosity, slag inclusions, lack of fusion, voids, and cracks disrupt the transmission of radiation and show up on the radiograph, allowing inspectors to see flaws that aren’t visible on the surface. When performed with proper technique and safety, radiographic testing directly reveals internal weld conditions, so the statement is true. Keep in mind that very small flaws or certain geometries can challenge detection, and access and setup requirements influence what can be seen, but RT is specifically designed to detect internal weld defects.
