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?
Answer: 2G – Horizontal
The 2G position describes a groove weld where the weld axis is horizontal and the weld face lies in the vertical plane.
What is the minimum preheat temperature typically required for ASTM A36 steel with a thickness greater than 1.5 inches prior to welding?
Answer: 150°F (65°C)
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.
Which ASTM specification covers high-strength low-alloy structural steel shapes, plates, and bars intended for welded, bolted, and riveted construction?
Answer: ASTM A572
ASTM A572 covers HSLA structural steel in grades 42, 50, 55, 60, and 65, commonly used in welded, bolted, and riveted construction.
During visual inspection of a completed weld, an inspector finds a surface crack parallel to the weld axis. This defect is most likely a:
Answer: Longitudinal crack
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.
What does the term 'complete joint penetration' (CJP) weld mean in structural steel fabrication?
Answer: Weld metal penetrates the full thickness of the joint
A CJP weld requires the weld metal to penetrate 100% through the full thickness of the parts being joined, providing maximum joint strength.
Which standard governs the installation and inspection of high-strength structural bolts in steel construction?
Answer: RCSC Specification
The Research Council on Structural Connections (RCSC) Specification governs the design, installation, and inspection of high-strength bolted connections in structural steel.
When inspecting a snug-tight bolted connection, an inspector verifies that the bolts have been tightened to at least:
Answer: The condition achieved with full effort of an ironworker using a spud wrench
Snug-tight is defined by RCSC as the tightness attained with a few impacts of an impact wrench or the full manual effort of an ironworker with a standard spud wrench.
