Is Wedling Consumable Class Certification Mandatory?
(OP)
Dear Friends
Curently we are engaged in building new Semi-Submersible classed to DNV. We have for Piping GTAW/SMAW PQR Qualified to ASME IX / ABS Rules. Attending DNV Surveyor insist on using Consumables approved by DNV Class.
SFA 5.28 - ER80S-Ni1 for GTAW used in the PQR
Is there such manadatory requirement eiher in ASME / AWS D1.1 Codes?
Appreciate prompt reply.

It would seem logical but that would require the Engineer or Purchasing agent to actually determine the jurisdictional requirements and impart them into the Purchase documents. Perish the thought! It's so much easier to build it like we always have - or so it would seem from recent experience.
RE: Is Wedling Consumable Class Certification Mandatory?
Absolutely.
Your surveyor is right. I assume that the electrode is not approved by DNV Class?
RE: Is Wedling Consumable Class Certification Mandatory?
It is not an issue of logic. Is it Mandatory? Is it called in DNV Rules or ASME Code?
Most often we use Kobelco/ Esab Consumables and Kobelco as manufacturer and even some of its consumables approved by DNV Class as well but NOT all.
At the same time it is almost impractical or not cost efficient to get all the consumables certified to Classification Societies, isnt's it.And at the same time allmost all welding consumables manufactured in conformance with ASME SZect II - Part C.Isn;t it enough?
Thanks for all the advise
RE: Is Wedling Consumable Class Certification Mandatory?
You have been advised regarding ASME IX requirements as to AWS classification essential variables regarding qualification.
RE: Is Wedling Consumable Class Certification Mandatory?
It's not required per ASME rules, but, then if you're building to DNV rules that really doesn't matter. My experience in working to DNV rules is limited to topside equipment. In the particular case I'm thinking of, the applicable DNV rules addressed consumables and specified those approved by DNV or those qualified on the PQR.
I'd suggest you review the DNV rules that apply in this case.
