Re: [MW:29860] Asme Section IX Thickness range qualification

Thanks for the feedback

Yes, snap is ready WPS, follows attached.

But according to QW-451 because the coupon thickness is 25.4mm, the qualified range would be 5 to 2T, regardless of having deposited only 8mm with the GTAW process?

Thanks.

Yes you can, 

Your 25.4 mm with gtaw and smaw can write 2t ranges from your PQR for what has been deposited individually.

you are going to write a WPS or below snap is ready WPS?

Check impact / PWHT requirements for what you qualified and what recommended in production joint.

Thanks.

Dear Experts,

I have some difficulty to interpret the requirements of ASME section IX

I have a  PQR Based on a dual process GTAW+SMAW ( 8 mm+17,4 mm) on an 25,4 mm butt weld.

Can I make a weld using only the GTAW process, base metal with a thickness of less than 5mm?

Are the image conditions correct?

Please give with details explanation regarding my above difficulty.

Thanks and Regards

Isac
