Re: [MW:5923] PQR (QW-204b)

Hi


Accoding to QW 200.4:-
A combination of processes can be used for PQR, if THK of test coupon is at least 13 mm.

Since thk mentioned is more than 13mm So it is qualified for Multiprocess welding.

Max. deposited thickness qualified for each process shall be 2*t.

So your ranges are qualified & can be recorded in WPS.

Hi,



Have the following question regarding weld metal deposition
on PQR with combined GTAW & MMAW processes.

Have recorded both GTAW = 3.5mm & MMAW = 9.8mm onto PQR
(QW-204b) but unsure of the ranges qualified

for both and should they be recorded on associated WPS.



Thanks

QA/QC
