your right Al, I don't have to meet any code requirement, I wanted to, but as I mentioned earlier we are going to scrap the Idea, for many reasons.
1st reason, the flux the engineer said we have to use (Lincoln 880M) is too course for the handheld SAW unless we special order it(added cost)
2nd reason, The wire the EOR said we must use(EM12K) has a silicon content of .10/.35 and for that flux if Si is less than .20 you have a better chance of porosity among other things(I'm not at work with all the info so if I'm wrong on any of this I'll edit tomorrow)
Another reason as mentioned before is the wire size, we were hoping to increase from 3/32" wire, and thats not possible with the handheld SAW.
we are now working on an automated FCAW system to weld the grooves, which,by the way, has to be welded 3 layers then move to the next for 3 layers and so on. That is the hard part, getting set up with a man-lift and preheating each arm to only put 3 layers of weld before moving to the next! (thats where our 120k lb positioner comes in handy, these weigh upwards of 40k lbs)
Initially, I talked to our company engineer and he said he has done it before using ASME, so I was wanting to do it to a code just for the sake of having a WPS on hand for future jobs. according to our customers engineers, they would OK the procedure using the filler and flux mentioned if we sent them a sample plate for them to bend. so your right, no code requirement.
My company wanted to do it to a code, but I see now thats not feasible and would actually end up being more costly without shaving much time.
Hg, I don't have D1.5, we don't do any bridge work. but I appreciate the input, as I do from everyone.
Beware of chinese chains also, our new purchasing guy bought some chains(found out they were from china after the fact) rated at 48K lbs at 60 degrees. we started picking up a 38k LB cutter at about 5 degrees(hooks almost straight below block) and the 5/8" chains snapped causing a slight earthquake in the shop.
You're lucky the chain didn't induce a "spin" on the cutter head when it broke. From the looks of the photos of the cutter heads, you would have had a hole half way down to China. Since a portion of the chain was still attached, you could have asked the Chinaman that made the chain for your money back!
Best regards - Al
I do not know about your purchasing people, but at my workplace, the only thing the purchasing agents know is cheap, cheaper, or even cheaper.

Why is your EOR dictating which consumables to use?
Hg
We have a spec book we have to follow, listing the consumables that we are allowed to use! there are a team of engineers that design these things including what consumables to use, after talking with them, they don't want to budge. thats the only reason I can give.
follow the rules or find new work! I think its much easier to follow the rules. :)
