Report ID: ASME-WELD-2024-001
Date: [Current Date]
Author: Engineering Standards Division

• Welding process (SMAW, GTAW, GMAW, SAW, etc.)
• Base metal specifications (P-Numbers, Group Numbers)
• Filler metal specifications (A-Number, F-Number)
• Position (1G, 2G, 3G, 4G, 5G, 6G)
• Preheat, interpass temperature, PWHT
• Electrical parameters (current, voltage, travel speed)

• SMAW (QW-252): Electrode classification, F-number, A-number (chemical composition), thickness, pipe diameter.
• GTAW (QW-253): Shielding gas composition, backing gas, addition of filler metal.
• GMAW (QW-254): Transfer mode (short-circuiting vs. spray), shielding gas, wire feed speed.
• SAW (QW-255): Flux brand & type, number of electrodes.

Welder Performance Qualification (WPQ): A record of tests (visual, mechanical, or radiographic) used to determine a welder's ability to deposit sound weld metal using a specific process. Key Qualification Variables welding standard asme

4.3 ASME Section V (NDE)

• Section IX mandates visual examination (QW-191) and may require RT or PT per the WPS. Section V provides the detailed method.
