WPS Detail — Procedure record & validation findings

Qualified by PQR PQR-IEW-2026-107. Traceability established.

Base metal group P-No. 1 Gr.2 — ASTM A537 Cl.1 (N).

Joint is between identical P-Numbers — no dissimilar-metal restrictions apply.

Range 16–20 mm within qualified 16–20 mm for 20 mm test coupon.

Commercial range 16–20 mm is within conventional procedure limits.

Small-bore root check applicable to piping only.

Preheat ≥ 95°C satisfies the 10°C minimum for P-No. 1 base metal.

Interpass 200°C within 250°C ceiling (toughness-restricted).

Thermal window 95–200°C is internally coherent.

PWHT not invoked — permitted for this material/thickness/code combination.

PWHT not required — cycle parameters not applicable.

PWHT not required — soak band check not applicable.

F-No. 4 (E7018-1) is consistent with SMAW.

A-No. 1 weld deposit is chemically matched to P-No. 1.

SMAW is flux-shielded; external shielding correctly marked N/A.

SMAW — backing gas not driven by process.

Flux process — flow rate not applicable.

DCEP polarity consistent with SMAW and E7018-1.

Amperage 85–145 A inside the SMAW operating envelope.

Voltage 21–25 V inside the SMAW operating envelope.

Travel speed 110–180 mm/min is plausible for SMAW.

Heat input ≈ 1.98 kJ/mm within 2 kJ/mm toughness ceiling.

Position 3G is a recognised EN ISO 6947 / QW-461 designation.

Transfer-mode variable applies to GMAW only (SMAW exempt).

SMAW is an admissible process under ASME IX.

Notch-toughness regime declared — impacts covered as supplementary essential variables.

Tank WPS correctly qualified under ASME IX as referenced by API 650 §9.

IBR statutory route not applicable to this scope.

Administrative header fields adequately populated for issue.

Group No. 2 recorded for notch-toughness control.
