Which welding processes are included in the S classification test plate assembly for SMAW, GMAW and GTAW?

• A. SMAW only
• B. GMAW only
• C. GTAW only
• D. SMAW, GMAW and GTAW

Answer: (D)

The test plate assembly for the S classification is designed to prove that a welder can competently apply all three common structural welding processes. In structural fabrication, you may need to weld with SMAW, GMAW, or GTAW depending on joint type, thickness, access, and production requirements, so the plate setup is arranged to allow demonstrations with each method. Each process has distinct characteristics—SMAW is versatile for field or thicker sections, GMAW offers fast deposition for shop work, and GTAW provides high precision and quality for critical areas—and the S classification expects the welder to control heat input, produce sound welds, and avoid defects across all of them. Therefore, the plate assembly includes SMAW, GMAW, and GTAW to verify proficiency across the full range of processes used in structural welding.
