Dear Experts, If a PQR is qualified using ER70S-2 with impact testing, can we use the same PQR to prepare a WPS using ER70S-6, since both filler metals fall under the same F-Number and A-Number? Would this be acceptable under ASME Section IX, or would a new PQR be required? Your expert opinions and code references would be appreciated. -- 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.

Dear Mr Noble, ER 70S-6 in MIG welding consumable and ER 70S-2 is TIG consumable, hence both are different process and new qualification is required.   Regards, Sankaran.SP Coimbatore.  On Saturday, 10 October 2026 at 07:37:05 pm IST, Noble <noblejohny94@gmail.com> wrote: Dear Experts, If a PQR is qualified using ER70S-2 with impact testing, can we use the same PQR to prepare a WPS using ER70S-6, since both filler metals fall under the same F-Number and A-Number?

Just to add, after proper training and during Welder Qualification Test if you  don't control your welder to weld without UNDERCUT then how are you going to control while welding production joints. Some smart welders use Filing but it depends on the Client.

Respected Sir, You may proceed with either of the two options. However, the second option is recommended to minimize the risk of vessel deformation and protect the material properties during PWHT. 1. Proceed with a thickness of 50 mm. However, there is a significant possibility of changes in the material properties and vessel deformation due to the required temperature and holding time associated with the 50 mm thickness. 2. First, proceed with the 22 mm-thick vessel section, then perform local PWHT separately on the 50 mm-thick section to minimize the risk of adverse effects on the vessel material properties and dimensional stability.

Hello Team, Request to provide details of the equivalent ASME Grade for  EN 1.4306 or EN1.4307. Also i had try to down EN specification from the authorized portal but unable to find the mother specification for these grades.  Thanks & Regards, Dharmesh Mistry -- 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.

Dear Experts,  Can anyone share the inspection requirements or a qualification procedure for cold bending? Our client spec states only the requirements for induction bending and would like to know your opinion on the cold bend inspection requirements. The code of construction is B31.3, Max. 5D bends, A106 SS 316L.  Thanks in Advance. -- 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.

Hi We manufacture cooling coils according to drawing codes and standards. In cold bending, we check dimensions visually, thickness Reduction, and ovality. In process, we check hardness and perform PWHT if required by clients or codes. We also do  LPT Test on the knuckle area after forming. X ray of Weld Joints before and after PWHT.
