Dear experts, For procedure qualification as per ASME SEC IX- "Multiple PQRs may support one WPS", Likewise can we follow the same practice in AWS also?  Because which is not mentioned directly on the code that we can use multiple PQRs to support one WPS.(And I'm not using prequalified WPS) Thanks & regards Prabaharan -- https://materials-welding.blogspot.com/ https://www.linkedin.com/groups/122787 --- You received this message because you are subscribed to the Google Groups "Materials & Welding" group.

5.2.2 Combination of WPSs. A combination of qualified and prequalified WPSs may be used without qualification of the combination, provided the limitation of essential variables applicable to each process is observed.

I suppose you can support only for welding positions. Unlike ASME Sec.IX code for process vessels & piping where the Load is uniform and the materials are restricted by code it allows for combination. But AWS D 1.1, you are subjected to Static, Dynamic & cyclic loading as well and as such there is no statement like ASME Sec.IX like combining WPS/PQR. Moreover you prepare WPS for 1 Pressure vessel and it is easy to control in the shop but whereas AWS D1.1 say for example offshore platforms, you have many varied components like Beam, Plates, girders, tubulars etc.. and it is difficult to control. Only for need based WPS to be used for AWS D1.1.

AWS D1.1 does not restrict the number of PQRs supporting a WPS. Clause 6 requires only that essential variables be validated by procedure  qualification testing. Where a single PQR does not cover all required variables of a production WPS, multiple PQRs may be combined to provide  full technical support. Therefore, using  multiple PQRs to support one WPS is fully acceptable and code-compliant.  Sridhar.

It depends on the project requirements. In our current project, we are using a hydrotest pressure chart recorder for both above-ground and underground lines, as per the specification requirements. If the company requires it, this should be clearly stated in the agreement and hydrotest specification, because it is not only for recording purposes but also involves additional cost. Please convey this to your Quality Management team; they will decide as per the agreement.    Best regards, Dominic V On Mon, 16 Feb 2026 at 11:39, Mahmood Alhinai < mahmood.m.alhinai@gmail.com > wrote: Dear experts, Kindly advise if any code or standard specify to use pressure chart recorder for piping spools hydrotest.

Dear Experts, Chart recorder are used only to keep evidence records for future reference. If it is not mentioned in client spec & in the approved procedure, you may strongly take up with client to avoid it. cordially, Jay Poojary On Mon, 16 Feb 2026, 11:39 Mahmood Alhinai < mahmood.m.alhinai@gmail.com > wrote: Dear experts, Kindly advise if any code or standard specify to use pressure chart recorder for piping spools hydrotest.

 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...
