AWS Destructive & Non-Destructive Testing 2

Question 1

Which destructive test measures the force required to pull apart two welded pieces in opposite directions along the weld axis?

Accepted Answer

Tensile test

Answer

The tensile test applies axial pulling force to measure a weld's ultimate tensile strength and ductility.

Question 2

In ultrasonic testing (UT), what does a high-amplitude signal returning earlier than expected typically indicate?

Accepted Answer

A surface crack near the transducer

Answer

An early, high-amplitude echo in UT indicates a reflector located close to the transducer, consistent with a near-surface discontinuity.

Question 3

Which AWS standard governs the qualification of welding procedure specifications (WPS) for structural steel?

Accepted Answer

AWS D1.1

Answer

AWS D1.1, Structural Welding Code—Steel, sets the requirements for WPS qualification including required mechanical tests.

Question 4

A fillet weld break test is performed primarily to evaluate which weld characteristic?

Accepted Answer

Internal soundness and fusion to the root

Answer

The fillet weld break (macro) test fractures the weld to reveal internal discontinuities such as lack of fusion, porosity, and cracks.

Question 5

In liquid penetrant testing, what is the purpose of the developer?

Accepted Answer

To draw entrapped penetrant out of discontinuities for visibility

Answer

The developer acts as a blotting agent, drawing the penetrant out of open discontinuities to create a visible indication.
