Upgrading SAW wire+flux combination according to AWS A5.17
Upgrading SAW wire+flux combination according to AWS A5.17
(OP)
I got a client (ASME III project + lots of client specs that are a combination of ISO and ASME/AWS points) that requires a qualification of the filler material according to A5.17.
So far so good, this can easily be arranged.
But - how do I document this? I am asked to write an "upgrading plan", which I am not familiar with.
I was hoping that, with a A5.17 test and an ASME IX PQR, it would suffice. But no.
Is this described somewhere, should I be using a certain template, what is the contents of such an "upgrading plan" ?

Is this a requirement listed in the project specification, ASME Section IX, Section III, where does it come from?

This is indeed a client requirement.
Apart from what I'm starting with (documentation of SAW wire and flux that we're going to use) and what I should end up with (chemical analysis and mechanical values), should I include any other info in such documentation?
I will ask the client, but I want to prepare a first version as complete as possible in order to have something to discuss in detail and to work further on.

I'm more concerned with completely documentating all of this, as I have never done this (the administrative part of it) before.

I documented manufacture of flux and batch number plus manufacturer an heat number of filler metal as well as flux filler classification. Documented electrical parameters and travel speed. Included welding operator and took photos of coupon set up and final welded coupon. Coupon was sent to an independent lab for machining and mechanical testing assuring that lab had proper documention of charpy test equipment. Witnessed measurement of test coupons and mechanical tests thereof.
For other such requirements, I had the manufacturer perform the welding and testing of the flux filler batches to be used in our production welding and they reported results.

@ weldstan, thanks for your experience. I'm planning to work very similar to your approach.

The flux, used for solid wire, also contributes to the chemical analysis of the deposited weld metal, and hence, to the mechanical values and so on.

Communication is key, but the customer sure made it difficult to reach them (each question needed a separate RFI and traceability number, ...). No "verbal/telephone" communication whatsoever. Not pleasant to work like that. Best of all, when witnessing the welding test, they (5 persons!) took of for coffee after taking pictures of the material stamps/filler material batches and after three welding passes. No more interest for amperage, interpass temp, ... because sub-arc welding is "boring"...
