# AWS D1.1 Structural Welding Code - Steel

> AWS D1.1/D1.1M, Structural Welding Code - Steel, published by the American Welding Society, covers design, prequalification and qualification of welding procedures and personnel, fabrication and inspection (including UT, RT, MT and PT acceptance criteria) for welded steel structures.

## Key facts

- Inspection clause (Clause 8 in current editions) gives visual and NDT acceptance criteria, with separate tables for statically and cyclically loaded structures
- Its UT procedure uses a specific calibration and indication rating method that differs from ASME V
- Allows prequalified WPSs within defined limits, avoiding procedure qualification tests
- Widely specified in mining, infrastructure and building projects, including in Australia alongside AS/NZS 1554

Also known as: AWS D1.1/D1.1M, D1.1.

## What inspectors do with it

Verify the WPS and welder qualifications, perform visual inspection to Clause 8 criteria, and apply the code's UT or RT acceptance tables. The report must state whether the structure is statically or cyclically loaded because the criteria differ.

## In AMPS

Because AMPS generates reports from your own Word templates, the code clause, acceptance criteria and revision block stay exactly as your QA system wrote them, with job data filled in automatically.
