AWS D1.1 Structural Welding Code – Steel

What it covers

• Prequalified WPS (joint details and parameters that may be used without procedure testing) and qualification by testing.
• Welder, welding operator and tack welder qualification.
• Workmanship, visual and NDT acceptance criteria for statically and cyclically loaded structures.

Key points for fabricators

• Common on projects designed to US practice (AISC 360) and in many export markets.
• Fillet sizes are given as leg length in AWS practice – not throat thickness.
