NDT Weld Inspection & Evaluation 2

Question 1

What is the correct sequence for measuring a fillet weld using a fillet weld gauge?

Accepted Answer

Place the gauge against the toe and read the leg size directly

Answer

Measure convexity first, then leg length

Answer

Measure throat first, then calculate leg size

Answer

Measure preheat temperature before gauge placement

Question 2

Which weld joint condition is described as incomplete joint penetration (IJP)?

Accepted Answer

Failure of the weld to extend through the full thickness of the joint

Answer

Weld metal deposited beyond the groove face

Answer

Excess reinforcement above the plate surface

Answer

Weld metal overlapping the base metal surface

Question 3

ASME Section IX requires that a welder's qualification test record include which minimum information?

Accepted Answer

Essential variables, test results, and date of qualification

Answer

Welder's home address and union number

Answer

Brand name of electrodes used during the test

Answer

Inspector's personal certification number only

Question 4

What is the minimum illumination level recommended by most codes for visual weld inspection?

Accepted Answer

100 foot-candles

Answer

50 foot-candles

Answer

200 foot-candles

Answer

500 foot-candles

Question 5

An overlap condition in a weld is best described as:

Accepted Answer

Weld metal that extends beyond the fusion zone onto the base metal without bonding

Answer

Two adjacent weld passes that are too close together

Answer

Excessive convexity in the weld crown

Answer

Base metal melted beyond the intended heat-affected zone

Question 6

When inspecting pipe welds in the 6G position, what does the '6G' designation indicate?

Accepted Answer

The pipe is fixed at a 45° incline and does not rotate

Answer

The pipe is horizontal and rotates during welding

Answer

The pipe is vertical with overhead welding only

Answer

The pipe is horizontal with flat position welding only

Question 7

Which of the following is a volumetric weld discontinuity detectable by radiographic testing but typically NOT by visual inspection alone?

Accepted Answer

Internal slag inclusion

Answer

Surface crack at the weld toe

Answer

Undercut along the weld edge

Answer

Weld spatter on the base metal
