CWI Practical Visual Inspection 2

Question 1

During a visual inspection of a fillet weld, you observe that the weld face is excessively convex. What is the primary concern with this condition?

Accepted Answer

It creates stress concentration at the weld toes

Answer

It indicates incomplete fusion at the weld root

Answer

It reduces the effective throat of the weld

Answer

It indicates the use of incorrect filler metal

Question 2

A CWI is inspecting a butt weld and notes the weld crown is lower than the base metal surface. This condition is known as:

Accepted Answer

Underfill

Answer

Undercut

Answer

Overlap

Answer

Concavity

Question 3

When visually inspecting for overlap on a fillet weld, you are looking for:

Accepted Answer

Weld metal that has flowed beyond the fusion zone onto the base metal without fusing

Answer

A weld that is wider than the specified size

Answer

Excessive reinforcement above the base metal

Answer

Porosity visible at the weld surface

Question 4

Which tool is most appropriate for measuring the depth of undercut in a weld?

Accepted Answer

Undercut gauge or dial depth gauge

Answer

Hi-Lo gauge

Answer

Fillet weld gauge

Answer

Welding magnifier

Question 5

During visual inspection, you find surface porosity on a completed weld bead. Which of the following is the most likely cause?

Accepted Answer

Contamination such as moisture, oil, or rust on the base metal or filler

Answer

Excessive preheat temperature

Answer

Improper post-weld heat treatment

Answer

Too slow a travel speed

Question 6

A weld inspector measures a fillet weld leg size and finds it is 3/8 inch on one leg and 1/2 inch on the other. What condition does this describe?

Accepted Answer

An unequal leg fillet weld

Answer

Acceptable variation within most codes

Answer

Undersize fillet weld

Answer

Convex weld profile

Question 7

What is the correct sequence for performing a visual inspection of a weld?

Accepted Answer

Inspect before, during, and after welding

Answer

Inspect only after the weld has fully cooled to ambient temperature

Answer

Inspect only the completed weld for final acceptance

Answer

Inspect only when the engineer requests it
