Thanks Metengr...I have another question...Does procedure qualification of P1 Group 3 (approx 80 ksi) metal qualify welding of P1 Group 2 or 1 (approx 65 /70 ksi)? I ask this on the basis of comparative strengths

Need some direction here. Can I qualify a procedure for AISI 4130 to a P1 Group 2 material and be qualified to weld AISI 4130 to a S1 Group 2...and if so can you direct me to some part of the ASME IX that reflects this, as I refer to some standard or code to justify this ?

The dimension is web to web.Yes it was engineered for loading by a helicopter. Any pointers on Heat Shrinking?

We are welding 5/16" mild steel plate on the top of a helideck to the top of W12x 16 beams with the spacing in between the beams are approximately 32". The fillet weld used is a 3/16" ("according to spec.") and we are using GMAW-S to minimise heat input. We are...

When materials do not fall under groupings in AWS what criteria is used in electrode selection for prequalification?

What are other the major variables in rod selection with materials, I know strength and position , but what are the others?

The AWS D 1.1 shows no grouping for this steel, what sort of rods can be used and where can I find guidance on similar non grouped materials for the AWS and ASME.

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

I need to qualify a WPS with a P1Gr1 to a P1Gr2 material ie Pipe(Gr1) to plate (Gr 2) does the AWS D 1.1 allow for such ? If so please direct me to it in the AWS.
