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

A fillet weld gauge is placed with its flat edge against the base metal and the perpendicular edge against the weld face, allowing direct reading of the leg size at the point of contact.

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

Incomplete joint penetration occurs when the weld metal does not extend through the full depth of the groove joint, leaving unfused base metal at the weld root.

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

ASME Section IX mandates that welder performance qualification records document essential variables (process, position, base metal, filler metal), test results, and the date the qualification was achieved.

Question 4

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

Accepted Answer

100 foot-candles

Answer

AWS D1.1 and most applicable codes require a minimum of 100 foot-candles (1076 lux) of illumination at the inspection surface to ensure adequate visibility of weld discontinuities.

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

Overlap is a surface discontinuity where weld metal flows over the base metal surface but fails to fuse with it, creating a notch-like condition that can trap moisture and initiate cracking.
