Re: [MW:34131] USE of PQR of 10.97mm GTAW+SMAW for new WPS GTAW process only

Thanks Mr. Jayakumar,

The impact test is No Applicable to our job.

Still, I have some doubts about preparing the WPS. Can you please review the area highlighted in the below screenshot? If changes are required, please let me know.

There are 2 thickness involved, Base metal (BM)Thickness and Weld metal (WM)thickness. Yes, you can prepare a separate WPS for GTAW from the PQR.

When Impact test is Applicable.

BM thickness Qualified,  minimum is 10.97mm so you cannot prepare a GTAW WPS.

When Impact test is not Applicable

BM thickness Qualified,  5mm to 7.0mm (though maximum is 21.94mm)


WM thickness Qualified is maximum 7mm

Thanks & Regards

I have a PQR of 10.97mm Test coupon GTAW(3.5mm)+SMAW(7.47mm) in groove Joint, ASME Sec IX . 

Can I prepare a new WPS for GTAW only for the Job with thickness 5.08mm groove joints? If Yes, What thickness range need to be mentioned in the WPS? 5mm to 7mm is Ok?
