Question

Material to be welded should be checked for physical condition prior to fabrication. This inspection might reveal:

A) Surface imperfections
B) Internal defects
C) Inadequate weld strength
D) All of the above

Answer 1

Before welding, materials should be inspected for both surface imperfections and internal defects, which are crucial for preventing inadequate weld strength once welding is complete.

Step-by-step explanation:

Material to be welded should indeed be checked for a physical condition prior to fabrication. This inspection might reveal surface imperfections such as pits and scratches that could affect the strength and quality of the weld. It might also uncover internal defects, which include issues like voids or cracks within the material that can compromise structural integrity. Additionally, assessing the material before welding does not directly measure weld strength; however, identifying imperfections and defects is crucial to prevent inadequate weld strength after the fabrication process is complete. Therefore, the correct answer to this question is both A) Surface imperfections and B) Internal defects, as they can be identified before welding occurs.
