How many joint configurations are there for the S classification SMAW, GMAW and GTAW test plate assembly?

• A. Two
• B. Three
• C. Four
• D. Five

Answer: (B)

The test plate assembly for the S classification is designed with three distinct joint configurations to evaluate a welder’s ability across the common plate weld scenarios encountered in shop fabrication. Having three configurations ensures the welder demonstrates control and quality in both groove and fillet welds across the three welding processes (SMAW, GMAW, GTAW). It’s a balanced approach that provides sufficient variety without becoming impractical in testing. That’s why the correct count is three. Using fewer would miss some joint types, while more would add more work than the standard qualification requires.
