ICC Commercial Building Inspector Practice Test

What standard governs welding inspection and inspector qualifications for reinforcing steel?

1. AWS D1.1

2. AWS D1.2

3. AWS D1.4

4. AWS D1.5

The correct answer is: AWS D1.4

The standard that governs welding inspection and inspector qualifications specifically for reinforcing steel is AWS D1.4. This standard focuses on the welding of steel reinforcement used in reinforced concrete structures, providing guidelines and requirements for both the welding processes and the qualifications of welding inspectors. It addresses various aspects of reinforcing steel welding, including the qualifications of welders and the inspection processes necessary to ensure that the welds meet the required standards for structural integrity and safety. On the other hand, AWS D1.1 pertains to structural welding of steel and covers a wider range of applications beyond just reinforcing steel, while AWS D1.2 focuses on the welding of aluminum structures. AWS D1.5 deals with bridge welding specifications, which also do not directly relate to reinforcing steel inspection and qualifications. Thus, AWS D1.4 is the appropriate standard to refer to for welding inspection in the context of reinforcing steel, making it the correct choice in this scenario.
