Reinforcement height and fillet weld sizes are measured with a

• A. Tape measure
• B. Video camera
• C. Magnifying glass
• D. Gauge

Answer: (D)

This item tests knowing that gauges are used to measure reinforcement height and weld sizes. Gauges are designed for precise, standardized measurement of weld dimensions, providing known openings or steps that you can compare directly to the weld to determine its reinforcement height and fillet weld throat or leg sizes. This is important because weld dimensions must meet code requirements and tolerances, and gauges allow quick, consistent, go/no-go checks that are much more accurate for small weld features than other tools. A tape measure isn’t precise enough for the small dimensions involved, a video camera can document a weld but needs a calibrated scale to measure accurately, and a magnifying glass helps visibility but doesn’t provide a reliable measurement reference.
