Materials & Welding

Dear Sir i have recived a comment from my customer on PQR submitted as our PQR/WPS code edition 2015 is PQR dated 07.02.2019 what is the format or document to show it was used in last year ,we are using same since last 5 year.  "'It is not allowed to use PQR issued five years before their application for the equipment construction unless VENDOR can demonstrate that the relevant WPS has been used during the last 5 years. The WPQR shall contain a document, which assure the welder activity shall be according to adopted Code"" . Kindly let me know what reply, and pls send me format of  Weld plan, weld map and test plan Regards asif Mulla -- 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,  I hope you are all very well. I wanted to know the reason behind why we use inconnect and E309L electrodes for buttering? what is the reason behind using those? Suppose a dissimilar weld between low alloy and carbon steel. We do buttering of inconnel on Low alloy metal. -- 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.

Let us know the production weld condition to respond to your query  The query can not be answered in isolation  Is PWHT is applicable ?  If yes PWHT Parameters? "Equipment service conditions?

Yes, PWHT is a requirement for Low alloy but not for Carbon steel. PWHT requirement for Low alloy is "heat upto 630-660 deg C and hold for 1hr and cool down to 400 deg C in controlled way and cooling to ambient should be done under insulation On Mon, Jul 29, 2024 at 9:21 AM Vishwas Keskar < vvkeskar123@gmail.com > wrote: Let us know the production weld condition to respond to your query  The query can not be answered in isolation  Is PWHT is applicable ?  If yes PWHT Parameters?

Dears, Vessel joint efficiency is 0.85 Vessel RT requirement is Spot.  Dished end having weld seam and fully RTd as the joint efficiency of head is 1 and other parts satisfied as per UW-52 spot RT requirements.
