Question 1

According to AWS D1.1, which welding position is defined as the weld axis being horizontal and the weld face being in the vertical plane?

Accepted Answer

2G – Horizontal

Answer

The 2G position describes a groove weld where the weld axis is horizontal and the weld face lies in the vertical plane.

Question 2

What is the minimum preheat temperature typically required for ASTM A36 steel with a thickness greater than 1.5 inches prior to welding?

Accepted Answer

150°F (65°C)

Answer

AWS D1.1 requires a minimum preheat of 150°F (65°C) for A36 steel thicker than 1.5 inches to prevent hydrogen-induced cracking.

Question 3

Which ASTM specification covers high-strength low-alloy structural steel shapes, plates, and bars intended for welded, bolted, and riveted construction?

Accepted Answer

ASTM A572

Answer

ASTM A572 covers HSLA structural steel in grades 42, 50, 55, 60, and 65, commonly used in welded, bolted, and riveted construction.

Question 4

During visual inspection of a completed weld, an inspector finds a surface crack parallel to the weld axis. This defect is most likely a:

Accepted Answer

Longitudinal crack

Answer

A crack running parallel to the weld axis (lengthwise along the weld) is classified as a longitudinal crack, often caused by hot-cracking or high residual stress.

Question 5

What does the term 'complete joint penetration' (CJP) weld mean in structural steel fabrication?

Accepted Answer

Weld metal penetrates the full thickness of the joint

Answer

A CJP weld requires the weld metal to penetrate 100% through the full thickness of the parts being joined, providing maximum joint strength.
