AWS structural steel ultrasonic testing is a non-destructive testing (NDT) method that uses ultrasonic waves to detect and diagnose defects in structural steel components.

AWS (American Welding Society) is a professional organization that develops standards for welding and related technologies, and the AWS structural steel ultrasonic testing standard provides guidelines for the performance of ultrasonic testing of structural steel components.

The standard covers a wide range of topics, including the types of defects that can be detected using ultrasonic testing, the test procedures and equipment that should be used, and the evaluation and interpretation of test results.

AWS structural steel ultrasonic testing is commonly used in the construction and inspection of buildings, bridges, and other structures that are made of structural steel. It is an important tool for ensuring the quality and reliability of these structures.
