Hello,
I have an existing PQR, done on a P1 Group 2 material (SA-516 Gr. 70), using 80 series wires (GMAW, FCAW, and SAW).
The tensiles for this PQR broke in the base at 78ksi and 77.6ksi.
No impact testing is required, so group number is NOT a supplemental essential variable.
Am I able...
Hello Everyone,
I know similar topics have been discussed but looking for some insight on my particular case.
I have two PQRs
PQR A: Groove weld, GTAW ER70S(deposited thickness: 1/4"), SMAW (Deposited thickness: 5/16"). Base metal: 9/16".
PQR B: Groove weld, GTAW ER80S (deposited thickness...
Hello,
I have an application that connects an API 6A Type 6B RTJ Raised Face flange to an API Type 6B RTJ Flat Face flanged choke valve.
Does any one have experience, or see an issue with mating a RTJ Raised Face to an RTJ Flat Face flange? I know that this is not recommended for typical...
Hello,
I have a PQR, welded with the SAW process that used electrode Lincolnweld L-56, AWS EH11K conforming to AWS A5.17
In lieu of an A-number, per QW-404.5 is it acceptable to put "All classifications" as indicated under Table QW-432 for SFA-5.17 or must I put "EH11K" for the A-number? For...
Hello,
I need to produce a PQR that requires impact testing, per ASME VIII Div. 1. Is it required that the material I use for the procedure qualification be impact tested? Material used in production would be impact tested, but I am wondering if my PQR material also requires it (of course, the...
Hello,
I have a PQR done with API 5L Gr. X65 pipe. Can I use this PQR/WPS to weld on an ASME Section VIII, Div. 1 vessel that uses SA-516 70 plate? The P numbers and group numbers are the same for both materials.
Thanks!
We have a local heat matching (Miller Proheat 35) and are fabricating a Vessel to ASME VIII, div 1 - requiring PWHT (made of SA 516-70 material). There are 4 longitudinal seams and 5 circumferential seams. Does anyone have experience in using local PWHT on longitudinal seams? Would like to do...
Hello,
I have a PQR/WPS that has been done with the typical bend and tensile tests. I no longer have the original sample that was used to perform these tests. We now need impact testing performed. If we use the exact same procedure & variables to weld another coupon, is there anything saying...
Hi guys,
I know a similar thread has been posted before but with a lot of argument, figured I would try to get an answer on my specific situation (ASME IX).
We currently have a PQR using GTAW and FCAW.
Base metal, T = 1.250"
GTAW deposit, t= .125"
FCAW deposit, t= remaining
Our WPS qualifies...
Hi Everyone,
We are welding stainless steel tube-to-tubesheets joints for one of our customers. We currently have a WPS/PQR to perform GTAW on stainless steel, which works for our application. However, our welder is finding that it is easier to not use any filler metal in welding these joints...
Hi Everyone.
Looking to do a PQR with a 0.50 x 13 threaded stud, welded onto plate per ASME IX. In regards to plate thickness that the stud will be welded too, does it matter? Was looking to do the PQR weld on a 1/2" plate. Also, if it does - what is the range of thickness that is then...
