AWS Weld Inspection & Quality Control 2

Question 1

Which destructive test is used to evaluate the ductility and soundness of a weld by bending a specimen over a specified radius?

Accepted Answer

Guided bend test

Answer

The guided bend test bends a weld specimen over a defined die radius to reveal surface or subsurface discontinuities and assess ductility.

Question 2

In ultrasonic testing (UT), what does the term 'DAC curve' stand for?

Accepted Answer

Distance Amplitude Correction curve

Answer

DAC (Distance Amplitude Correction) curve compensates for signal attenuation with increasing sound path distance in UT.

Question 3

What type of weld discontinuity is characterized by base metal melting away at the weld toe, creating a groove?

Accepted Answer

Undercut

Answer

Undercut is a groove melted into the base metal along the weld toe or root that is not filled by weld metal.

Question 4

According to AWS D1.1, which organization's RT film must be used when performing radiographic testing on structural welds?

Accepted Answer

Any film providing acceptable image quality as verified by IQI

Answer

AWS D1.1 requires that the radiographic film produce acceptable image quality as demonstrated by the image quality indicator (IQI), not a specific brand.

Question 5

A weld inspector finds a crack indications in a liquid penetrant test. What is the FIRST action that should be taken?

Accepted Answer

Mark and document the indication location before doing anything else

Answer

The first step is to mark and document the indication so that its exact location is recorded before any repair or further evaluation.
