Question 1

An inspector observes an underfilled groove weld where the weld metal surface is below the surrounding base metal surface. This condition is called:

Accepted Answer

Underfill

Answer

Underfill is a weld discontinuity where the weld metal does not fill the groove flush with the base metal surface, reducing the effective throat of the weld.

Question 2

What is the maximum permissible undercut depth for statically loaded non-tubular connections per AWS D1.1?

Accepted Answer

1/16 inch (1.6 mm)

Answer

AWS D1.1 permits undercut up to 1/16 inch (1.6 mm) for statically loaded non-tubular connections in most cases, provided it does not exceed 1/8 inch in length.

Question 3

Which non-destructive testing method uses high-frequency sound waves to detect internal weld discontinuities?

Accepted Answer

Ultrasonic testing (UT)

Answer

Ultrasonic testing (UT) uses high-frequency sound waves that are reflected by internal discontinuities, making it effective for detecting subsurface flaws in welds and base metal.

Question 4

For a pretensioned high-strength bolt connection, the turn-of-nut method requires bolts to be rotated beyond the snug-tight condition by how much for bolts with L/D ≤ 4 and both faces perpendicular to the bolt axis?

Accepted Answer

1/2 turn

Answer

The RCSC Specification requires 1/2 turn (180°) beyond snug-tight for bolt grip lengths up to and including 4 diameters when both connected parts have perpendicular faces.

Question 5

ASTM A325 and A490 high-strength bolts have been superseded by which ASTM standard?

Accepted Answer

ASTM F3125

Answer

ASTM F3125 is the consolidated standard that incorporates former ASTM A325, A490, F1852, and F2280 high-strength bolt specifications under grades A325, A490, F1852, and F2280.
