[MW:28289] Re: Can I use WPS/PQR P NO-1, Group NO-1 (PLATE) to P NO-1, Group NO-2 (PLATE) for welding of ASTM A333 Gr.6 (P No: 1, Group No: 1) to ASTM A350 Gr.LF2 CL.1 (P No: 1, Group No: 2) ?

Lets consider your case, the contractor is having Pipe (P1G1), Flange/ Fitting (P1G2). and may be going to have joints between

1. P1G1 to P1G1 (pipes to pipe)

2. P1G1 to P1G2 (pipe to fitting)

with above consideration,the qualification mandate CVN variable so the contractor require to have qualified WPS as per ASME Section IX for P1G1 to P1G1 and P1G1 to P1G2.

you must check the range of material thickness involved (You may need a combination of PQR/WPS to cover the thickness range for each above grouping).  Refer AW 403.5 & QW 403.6 for detailed condition.

Thanks & regards

Dear Experts,

1. WPS/PQR (P NO: 1, Group No-1 to P NO: 1, Group No-1 ) is available with contractor

2. Pipe material: ASTM A333 Gr.6 (P No: 1, Group No: 1)

     Flange/Fitting material: ASTM A350 Gr.LF2 CL.1 (P No: 1, Group No: 2)

     WPS/PQR ( P NO: 1, Group No-1 to P NO: 1, Group No-2 ) is not available with contractor 

3.  Charpy "V" notch test to be done

My query is 

 

Can I use WPS/PQR P NO-1, Group  NO-1 (PLATE) to P NO-1, Group NO-2 (PLATE)   for welding of  ASTM A333 Gr.6 (P No: 1, Group No: 1) to ASTM A350 Gr.LF2 CL.1 (P No: 1, Group No: 2) ?

Please give suggestions, Is it possible in accordance with ASME Section-IX  ?
