Engineer approval of WPS
Engineer approval of WPS
(OP)
AISC 341 requires that the fabricator submit WPS to the engineer for approval. I know very few engineers that are qualified to review and approve a WPS. How do firms deal with this requirement? One option, I guess, is to subcontract this function to a specialist firm. Is that really the intent?

If you are getting these then normally the welding inspector you would get to inspect the welding would review and approve.
If you're not going to do anything with the WPS, then at least make sure the qualification test matches the WPS! and is in date.
My motto: Learn something new every day
Also: There's usually a good reason why everyone does it that way

LaCount....A Welding Procedure Specification is relatively straightforward. Its variables are contained in the welding code (typically AWS D1.1). There are nuances of course, but with a little reasonable self-education and a visit to a fab shop you will see it unfold.
The WPS is intended to be used. It is not an administrative exercise meant only for filing.

In Engineering Liability 101 you learn that you don't reference or specify a standard you haven't read and reasonably understand.....common sense. Further...if you specify a standard, you had better have it in your library!! My specialty is forensics....I see engineers get raked over the coals by attorneys for this kind of stuff....you don't need it. It isn't that difficult to get up to speed on these things.
Remember.....everything you write, draw or think will be second guessed by someone....probably a lawyer. Be prepared.

I'll eyeball the rest of it to make sure there aren't glaring issues, but otherwise it should be good to go.
I mean, generally it's either straight out of the prequalified welds, or it's been tested and qualified. Either way, it's pretty straightforward.

I left the site quickly thereafter.

I am in a tricky position because the welds are 99% probably fine for their intended purpose (this fabricator is generally very good), but the paper is a mess, and as a designer I rely on paperwork. What's worse, a messed up project with liquidated damages, or the liability of not having paperwork?
