 ASME B31.3 refers ASME Sec.IX for WPS/PQR qualification. PWHT Soak time after Repair will be considered during original PQR qualification and when Charpy Impact tests are required, below snap shot of ASME Sec.IX applies. Normally in Pipe Mill, MPQ (Manufacturer Procedure Qualification) with welding & Heat Treatment will be performed including repair PWHT cycles during pipe production.

Hello, Dear Expert, I would appreciate your insights on the following question concerning heat input calculations for impact-tested WPS. The Qualification Code is ASME Sec. IX. Yes, there is an impact test. The contractor has submitted the WPS heat input, which is shown in the screenshot below. (The second last and last columns were added by me. Question: How do you calculate heat input? 1. Third Last Column: The contractor recorded the highest heat input from PQR on the WPS as it is. 2. Second Last Column: Heat input is computed by averaging the amperage, voltage, and travel speed. 3. Last Column: The calculation of heat input relies on the maximum amperage, voltage, and travel speed. Which method is the correct one for calculating heat input? Heat Input will be higher than from PQR with available variables.  Reference :  Table QW-253 Welding Variables Procedure Specifications (WPS) — Shielded Metal-Arc Welding (SMAW) QW-409.1 Increase in heat input shall be consdire essential variabl...

Hi, There are some noticeable portions in your below table for Heat Input. 1. Your contractor has provided average Heat Input but according to ASME Sec.IX , it is the maximum Heat Input. 2. In your Cap pass, Heat Input is very High since for cap pass you use 2.5mm electrode and the Travel speed will be relatively faster and the allowable Current ranges for 2.5mm electrodes as provided welding consumable manufacturer may not be in this limit. For GTAW & SMAW  process, the code ASME Sec,IX provides the below formula. Ways for representation of  Heat Input for each Pass (RooT, Hot/cold, Fill & Cap passes). You can use a Portable arc monitor (PAM) unit to measure Heat Input or use Tong tester for measuring Current & voltage and stop watch to measure Travel Speed. When charpy tests are required Heat Input is a supplementary essential variable. Way 1 As per ASME Sec,IX, you can mention only the maximum limit of the Heat Input for ach pass no minimum limit applies. Way2...

Super Duplex have a Tensile strength of 115ksi whereas duplex have a Tensile strength of 95 ksi. You cannot use a duplex PQR to weld super duplex SS though P.No/F.No/A.No(if used super duplex) are same but additional requirements like Corrosion test restricts them Thanks & Regards J.Gerald Jayakumar 0091-8838619635 On Monday, 2 February 2026 at 04:19:32 pm IST, Mohmmed Dudhiyawala <mdudhiya007@gmail.com> wrote: DSS and SDSS are same group no. as per ASME IX. i.e. P10H G1 On Monday, December 15, 2025 at 10:05:44 PM UTC+5:30 syed kauser ahmed wrote: As per ASME Section IX – QW-403.5: No, a change from one Group Number to another Group Number within the same P-Number shall be considered an essential variable and requires requalification of the WPS.

1.  Tensile Test (ISO 4136 / ASTM E8) Purpose:      Determine yield strength, UTS, and elongation. Specimen:  Transverse or all-weld-metal, machined to standard dimensions. Procedure:   Mount the  two specimens in a calibrated tensile machine. Apply load at controlled strain rate until fracture.   Record YS, UTS, EL%. Acceptance:  Tensile ≥ minimum specified; fracture location acceptable.   2.  Bend Test (ISO 5173 / ASTM E190 / AWS B4.0 ) Purpose:       Check ductility and weld soundness. Specimen:     Face/root/side bend, edges smoothed. Procedure:   Bend to 180° around specified mandrel. Inspect tension surface. Acceptance:  No cracks > 3 mm; no open defects.   3. Vickers Hardness Test (ISO 6507 /  ASTM E92 / AWS A4.2 ) Purpose:        Evaluate hardness of WM, HAZ, BM. Specimen:     Polished transverse section; HV10 or HV5 load. Procedure:   Apply load for 10–15 s. Take impressions across the weld line.   Record hardness profile. Acceptance:  Project-specific (e.g., ≤ 250 HV10 for...
