General awareness of metallurgy is important to the welding inspector because:

• A.Physical properties of the final weldment can be significantly affected by preheat and postweld heat treatment (PWHT).
• B.Welding processes can affect both mechanical and corrosion properties of a weldment.
• C.The crystalline structure of base metals affects the resulting structure of the weld.
• D.A thorough knowledge of weld metal structures is necessary to understand weldability.

What is the "area of interest" on a weld radiograph?

• A.The entire radiograph minus 2 in. (50.8 mm) from the edges
• B.The portion that is less than 3t from the center of the radiograph, where t is the thickness of the weld
• C.Only the area of contrasting density
• D.The specific portion of a radiograph that needs to be evaluated
