For a SAW weld, the effective throat may be considered equivalent to which size?

• A. The original fillet size
• B. The base metal thickness
• C. The next larger fillet size expressed in millimeters
• D. The weld length in inches

Answer: (C)

In a SAW weld, the throat dimension that governs the weld’s strength is often larger than the simple fillet geometry. To keep evaluation conservative and straightforward, the effective throat is treated as the next standard fillet size expressed in millimeters. That means you use the next larger fillet size value as the throat, providing a safe, conservative estimate of the weld’s capacity. The other options don’t fit because the original fillet size would underestimate the throat, base metal thickness isn’t a measure of throat, and weld length isn’t related to the throat dimension.
