ASME SECTION IX Welding Procedure Qualification
ASME SECTION IX Welding Procedure Qualification
(OP)
Friends,
I have an existing pipe weld procedure(GTAW/SMAW) qualified for P1 material using ER 70S3 filler wire and E-7018 electrode.
impact at -20º
Can I use the same procedure for an API 5L grade X52 material?
Please help

RE: ASME SECTION IX Welding Procedure Qualification
If the API 5L grade X52 requires impact testing for service, your procedure above would not work because you have not qualified to a specific Group No. When you qualify weld procedure specifications to ASME Section IX, in addition to the P-No or S-No, the Group No also becomes an essential variable.
RE: ASME SECTION IX Welding Procedure Qualification
The P-No 1 WPS above cannot be used for welding this material for applications under ASME B31 Piping Code. You would need to qualify a WPS for the API 5L grade x52 material.

Agreed on the use of this procedure for non-impact applications in B31 Piping Code. The last sentence in my second post is confusing because I had forgot to type the word "impact" for applications under B31 Piping Code. Good catch.
