Dear Mr. Mac,
Supplemeting to Mr. Sridhar's excellent reply
AWS D 1.1 qualification is on volumetric NDT (UT & RT)
AWS D 1.1 has pre-qualified / recognized list of materials
If the material you referred in your original email, if they are also find mentioned in AWS D 1.1 then fine. Else you need to re-qualify.
With regards,
Sreeram_Srinivas

Dear Mr. Mac,Pl. refer to your mail towards clarifications over performance Qualification of welders and our viewsas follows:1. welder qual. done as per sec. IX of ASME in 6G on CS shall qualify him for both pipe & plate andin all positions and fillets of all thicknesses in all positions.2. AWS D 1.1 also follows ASME for welding part. Hence no problem & no separate qual. test is required.3. But you have not mentioned the type of consumable used in your 6G position qualf. test.4. If you have used E 6013 (F2), in your 6G welding, then you can use only F2 & F1 type cons.5. If you have used E 7018 (F4), then, it qualifys all F4, F3, F2 & F1.6. Hence, if you are going to use E 7018 in your H-beam welding, think of points 4 & 5 and decide.If it was F2, then do Fillet weld qual. test as per any code. If not, no need to worry.7. If you have used E 7018 and TPI is still particular of AWS D1.1, you can prepare a new WPS and encloseyour approved ASME sec. IX WPS & PQR docs. as a supportAWS accepts pre-qualified WPS done as per ASME in structural welding also.8. But mind again points 4 & 5 and decide.9. Hope, it clarifys all your points.Confirm the results for our records.Regards,Sridhar.

Subject: [MW:24761] PERFORMANCE QUALIFICATION

Dear Sir,
(B31.1 Code) We have a qualified pipe welder with 6G position (18.26 thickness test coupon), as per ASME Sec IX Table QW-461.9, he is qualified for all positions for groove and fillet weld - plate and pipe.
This qualified welder was task to weld pipe support (H Beam), It has been questioned by the TPI that this welder should be qualified again as per AWS D1.1.
My Questions are;
1. Should we qualify this welder again as per AWS D1.1? If yes, what is the supporting code for this.
2. Does ASME Sec IX Rules for this situation?
Need your advise.....
Thank you
Mac Palola
