Re: [MW:13947] Impact test requirements as per UG 84

Dear Samshuddin,

1. Attached Sketch might usefull for better understanding ( ignore the PG-PDS additional client requirement)

2. It's not each process (refer sketch)

3. Even you can go for 3cycle PWHT.

Subject: [MW:13920] Impact test requirements as per UG 84

Dear Experts
I have to prepare a PQR for SA 516 Gr.70 plate of 50mm thick.
I am using GTAW+SMAW+SAW(10mm+20mm+20mm)
My doubt is how many test specimen i have take for impact test
Is that i have to take HAZ & WELD from each process.
Please expalin.
And as per UCS 56, I am going to do PWHT.
Then can i take twice the holding time to considering the on job repair.
Is that acceptable
Please advise
