Dear ...

Its purely based on your project specification requirements, If they have mentioned All structural Weldings and Welding procedures shall be as per ASW D1.1, then only You need to Qualify a procedure based on ASW D1.1 ...

If Your project spec says all Welding Related as per ASME Section IX , your qualified welder in 6G is acceptable for Beam welding.

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,

Dear Mr. Mac,

Pl. refer to your mail towards clarifications over performance Qualification of welders and our views

as follows:

1. welder qual. done as per sec. IX of ASME in 6G on CS shall qualify him for both pipe & plate and 

    in 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 enclose 

    your approved ASME sec. IX  WPS & PQR docs. as a support 

    AWS 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
