Prequalified WPS route checker

Record the main Clause 5 gates and identify known route failures or missing evidence.

Code scope and process

Code basis

Work type

Confirmed within D1.1 material/structural scope, minimum thickness and specified yield-strength limits?

Screen Clause 1.1 scope (including ≥1/8 in [3 mm] and specified minimum yield strength ≤100 ksi [690 MPa]); mark Yes only after checking actual material and design basis.

Loading / contract condition

Special contract requirements reviewed by responsible reviewer?

Welding process

Power source for GMAW/FCAW

Clause 5 evidence

Both base metals exactly matched to Table 5.6 by specification, grade and condition?

Record each member separately; similar strength or a trade name is not a match.

Filler/flux/gas combination matched to applicable Table 5.7 and 5.6 requirements?

Joint type and full detail fit a permitted Clause 5 detail for this member, process, position and thickness?

Include CJP/PJP/fillet, backing, root opening, root face, angle, access and backgouging. Tubular requires Clause 10 review.

Preheat/interpass category and minimum satisfy Table 5.11 and applicable project/material restrictions?

Position and every applicable process-table limit (Tables 5.1–5.4) are satisfied?

All Table 5.5 variables are recorded and planned operating ranges stay within its tolerances?

Vertical progression and pass geometry satisfy 5.8, including uphill rule and bead cross-section?

PWHT absent, or every Clause 5.9 condition including Engineer approval is met?

CVN / supplemental toughness requirements have been checked and supported for this route?

If tubular: exact connection, loading category and Clause 10 details have been reviewed?

Do not treat an HSS member alone as proof that Clause 10 applies or does not apply.

Scope & references AWS D1.1 / D1.1M:2025

2025 base edition with July 28, 2026 errata. AMD1 not included.

Guided checklist only; tubular and special contract cases need complete specialist review.

Decision sequence

Check the code scope and loading, process eligibility, each base metal, filler, joint detail, preheat, process table, Table 5.5 variables and special branches.

Result boundary

Clause 5 route screening is not engineering approval, WPS signature, personnel qualification or weld acceptance.
