Is it acceptable according to AWS D1.1?

[4872]

Dear Friends
Applicable Code - AWS D.1.1- Sect 4 Part B-Table 4.8.
In Module Skid Fabrication European Steel- S355JR, S275JR,A355JO used( Unlisted Material in AWS D.1.1).
Is it right/appropriate to use WPS/PQR Qualified using EH36 as base material?
If acceptable, pls advise ref. section of the code.
If not accepatable.what is the option? Require requalification?
Pls advise, Thanks.

Unless the material is certified as such, you would require requalification as it is an unlisted material.

Can you match the steel properties with the ASTM materials given in D1.1? If yes, then the WPS/PQR can be related accordingly.

If not, re-qualification of welds and welder is required.

The above approach would not seem to meet the requirements of Table 4.8
