Re:PQR Groupings
(OP)
Sorry,
My mistake, but my problem still lies in Gr 1 to Gr 2 materials (AWS Groupings).I need to figure out whether a Welding Procedure can be qualified with these two different type materials.
Thanks

RE: Re:PQR Groupings
I qualified more ASME procedures than AWS procedures. I had qualified procedures for P1 to P8, P5A to P5B - I also had one for inconel to stainless (P45-P8? I can't remember the P numbers for certain). I think the primary difference betwen the two procedures was the Charpy testing required in AWS that was not required for my ASME procedures (or was it API that required Charpy?)
Have you reviewed the applicable AWS standards? Which AWS code are you using? Do you have a copy of AWS B2.1?
RE: Re:PQR Groupings
LeAnne,
P1 CS
P5A LAHT
P45 Inconel
P8 SS
So your memory serves you right!!!
The eariler editions of AWS upto 2000 did not call for impact...it was generally a client specification requirement. But the recent edition has clauses for impact testing too. I am not sure however if API calls for impact....if my memory serves me right API refers to ASME Sec IX for qualification(s)!
