AWS Inspection & Quality Control 2

Question 1

Which destructive test is used to evaluate the ductility of a weld by bending the specimen until it fractures?

Accepted Answer

Guided bend test

Answer

The guided bend test bends the weld specimen to a specified radius to evaluate ductility and reveal surface or subsurface defects.

Question 2

What type of weld discontinuity is characterized by the weld metal not fusing completely with the base metal or previous weld pass?

Accepted Answer

Incomplete fusion

Answer

Incomplete fusion (lack of fusion) occurs when the weld metal fails to bond properly with the base metal or adjacent weld passes.

Question 3

When performing visual inspection of a completed weld, which measurement tool is used to verify fillet weld leg size and throat?

Accepted Answer

Fillet weld gauge

Answer

A fillet weld gauge is specifically designed to measure the leg size, throat, and convexity or concavity of fillet welds.

Question 4

What is the AWS definition of a 'discontinuity' in a weld?

Accepted Answer

An interruption in the typical structure of a weld

Answer

AWS defines a discontinuity as an interruption of the typical structure of a material, including lack of homogeneity in mechanical, metallurgical, or physical characteristics.

Question 5

In radiographic testing of welds, what does image quality indicator (IQI) verify?

Accepted Answer

The sensitivity and quality of the radiographic image

Answer

An IQI (penetrameter) is placed on the weld to verify that the radiograph has sufficient sensitivity to detect discontinuities of a specified size.
