Dear    ASTM A333 and ASTM A106 are both carbon steel pipe specifications, but they serve different purposes and have distinct characteristics. ASTM A333 pipes are designed for low-temperature service, typically below -50°F (-45°C). They are made from low-temperature carbon steel and are suitable for applications where the pipes will be exposed to cold temperatures. ASTM A106 pipes, on the other hand, are suitable for high-temperature service and are often used in power plants, refineries, and other high-temperature applications. The main differences between A333 and A106 pipes are: 1.Temperature range: A333 pipes are designed for low temperatures, while A106 pipes are suitable for higher temperatures. 2. Material composition: A333 pipes have a specific chemical composition that ensures low-temperature toughness, while A106 pipes have a different composition that prioritizes high-temperature strength. 3. Mechanical properties: A333 pipes have specific requirements for impact testing an...

Dear Experts, We have a qualified PQR (P1 to P8) that doesn't include hardness testing. We're submitting this PQR for a new project, but the client requires hardness testing. To address this, we plan to: 1. Create a new PQR following the same parameters as the original PQR. 2. Conduct hardness testing and add the results to the new PQR. We're unsure about the best approach to incorporate the hardness test results into our existing PQR documentation. We have two options: Option 1- Add the hardness values to the original PQR as Addendum-1. Option 2- Create a new PQR that includes all the previous data and name it as a Supplementary PQR. Could you please guide us on the best approach to take?

You can make a new, "Supplementary PQR" as it is s afer and cleaner from a compliance and transparency  standpoint.  You prepare a new PQR document with all the welding parameters repeated from the original PQR, plus the new hardness test results.              You can add a note referencing the original PQR number (i.e., "This PQR was performed under the same welding conditions as PQR-001 (provide actual details) to incorporate the hardness testing per client requirements").

Dear Sir,  I have one doubt  For the WPS submission I have to Attach the new Supplementary PQR and old PQR together with the new WPS.  In supplementary PQR format we can just add new hardness testing values rest other testing values are already in old PQR or we need to write in new supplementary PQR format also. And we can attach old welding parameters sheet along with new supplementary PQR and in PQR format instead of PWPS no we can write Old PQR no which we are referring to.

Hi Pankaj Your 1. OLD PQR will be unchanged (say PQR1), which has all the variables and necessary tests completed and qualified with WPS 1 2. Supplementary PQR will have all the variables within the range of PQR1/WPS1, and the test carried out will be Hardness (as this is the requirement). Basis of welding this PQR will be WPS1 3. Revise WPS1 to add Supplementary PQR in addition to PQR1 Regards,   Prashant P Rane On Thu, Aug 28, 2025 at 1:25 PM pankaj pachahara < pankajpachahara@gmail.com > wrote: Dear Sir,  I have one doubt  For the WPS submission I have to Attach the new Supplementary PQR and old PQR together with the new WPS.  In supplementary PQR format we can just add new hardness testing values rest other testing values are already in old PQR or we need to write in new supplementary PQR format also.

Just to add, Supplementary  PQR will always be a part of PQR package containing the Original PQR Number with the supplementary indicator when you submit your WPS for Approval. It also includes the As-run sheet & the Hardness test Results. Instead of using a Proposed WPS, you can use the original Approved WPS to weld(depends on Client).

You need to write in the new supplementary PQR format as the hardness testing date is current. Since the old PQR results (other than hardness values- as per the standard) are the same, it is not necessary  to enclose the old PQR. But, if your client insists, please act to satisfy him.

Dear sir,    As it is client requirement, and every client has its own specifications. In Aramco SAES-W-010 para 7.5.2 is asking to weld a coupon to comply all essential requirements of the PQR and conduct only hardness testing. But you have better experience and your observation will be beneficial.

Please refer to ASME sec IX - QW-200.2 & QW-401.1. While ASME IX does not explicitly use the term "supplementary PQR", industry practice is to weld a new coupon  with the same WPS variables, which is issued as a new PQR; i.e., o ne cannot add hardness test results to the original  PQR, because that would not represent the same coupon. You must weld a new coupon and issue a new PQR with  hardness results, and cross-reference the original PQR if traceability is required . C Sridhar.

Dear experts. I am currently in the process of qualifying a PQR for API 5L X65 + A350 LF6. Both material consists of a base metal with alloy 0625 cladding. Welding process: GTAW+SMAW During the mechanical testing, I witnessed the following hardness values: Clad material: 300 to 390 HV Weld metal: 280 to 350 HV This is for Aramco project, so I referred their standard 01-SAMSS-044, and it specifies that I must refer to NACE MR0175/ISO 15156 for hardness acceptance criteria, particularly for the clad. I have reviewed the standard but cannot find a specific acceptable hardness range. I also checked Aramco's W-11/W-12 and W-16 standards but was unable to find the maximum allowable hardness for clad welding. My question is: Are these recorded hardness values for the clad and weld metal acceptable under the NACE MR0175/ISO 15156 standard? If not, what are the typical hardness limitations and under which standard? Regards  Saurabh Jain -- https://materials-welding.blogspot.com/ ...

Dear Sir, I need to clarify some sentences  in the AWS D1.1 2025 edition 1. table 6.6   PQR essential variable changes.. for voltage > 07 %, current  >10% increase or decrease......if  PQR qualified range 26 to 28 V and 170 to 180 A  then how much value we can keep for min to max for range qualification, either consider higher side value or lower side value 2. For CVN test min thick qualification 1 2 mm to unlimited   for 25 mm thick weld coupon plate but  we need below 12 mm plate thick qualification we have taken 06 mm weld coupon plate thick. but standard mentioned... minimum thickness qualification 03 mm   we need 03 mm thick ness to unlimited thickness QUALIFICATION what should do..   a)  either required two weld coupons 25 mm and 06 mm thickness those 25 mm weld coupons complete the limite 12 mm to unlimited and 06 mm weld coupons complete the limite 2T that is 03 mm to 12 mm Thick....

Below information is for your clarification, If you qualify with  26- 28 voltage the range of qualification for voltage is 24.18 - 29.96V and Current 153A - 198A. For CVN for 25mm range of qualification is 12 to unlimited. For 6mm range of qualification is 6mm to 12mm. Inorder to cover from 3mm, We need weld one coupon whose thickness is less than 6mm then (Eg: 5.9) it will cover from 3 mm to 11.8mm.
