Welding Wps Variables: ESW
ASME BPVC Section IX and AWS D1.1 welding procedure specification (WPS) essential, supplementary essential, and nonessential variables for 8 processes (SMAW, GMAW, GTAW, FCAW, SAW, ESW, EGW, PAW) with QW variable numbers, requalification requirements, and P-number applicability
| welding process | variable key | P number applicability | QW variable number | description | notes | requalification required | typical range or limits | variable category | variable name | variable type |
|---|---|---|---|---|---|---|---|---|---|---|
| ESW | essential#QW-403.11 | all | QW-403.11 | Change in P-Number of base metal | ESW produces very high heat input; limited to thick sections (>1.5 in) | yes | P-1 through P-5F primarily; ESW limited to heavy structural applications | base_metal | P-Number change | essential |
| ESW | essential#QW-403.8 | all | QW-403.8 | Change in base metal thickness outside qualified range | Maximum thickness typically unlimited if 2T rule applied | yes | Per QW-451; ESW qualified range typically 1.5 in to 8 in | base_metal | Thickness range | essential |
