Cactus, I did a search and found this. This standard describes manual, semiautomatic, and automatic field welding by the metal arc-welding.

If not, you might keep in mind you will need a sufficient sized air mover to keep the smoke clear for the inside welders, at whose expense providing, fueling and keeping that running will be yours to wrangle with the General.
Puget Sound Olympic – Section My IOR was clueless about welding. Not logged in American Welding Society Forum. Again not rocket science, but I hate seeing guys re-inventing the wheel.
Florida West Coast – Section Water work is generally IMHO far less critically challenging, but every application in this trade has its tricks, short cuts and learning curve and I thought I might pass on the few crumbs I’ve gleaned from my limited time in those particular trenches.
As I have recently completed inspection on a storm water pumping station with AWWA listed as the ruling code, I will say I was suprised that the code offered little guidance.
By dbigkahunna Date It also list the welds to be performed with 70xx. Other welding required in field fabrication and installation of specials and appurtenances is also discussed.
It will typically refer to D1.
Not being familiar with the accept reject to D1. That largely depends on length of line awwaa psi- might be something to look into.
On a 20 mile 42″ line I rig 2c06 on with the 70XX requirements the welding contractor had me qualified with a a full pen 5P, 6″, 6g qualification examined to D1. Having read postings from you in the past, it appears you tend to focus and specialize more in the gas and energy business than large bore waterlines. We will be doing a 36″ waterline and that is the only awwa that is implied on the drawings.
Arizona – Section Something to chew over maybe anyway. San Francisco – Section Rochester – Section By yojimbo Date The design of field-welded joints is not described.
May want to go over your continuity logs to be sure everyone is current. Welding of gasketed joints may require modification to the parameters of this welding standard.
I did initial inspection and follow up inspection after they allowed repairs to parts that didn’t line up with their pumping station. That pretty much answered my question and my curiosity. It is possible to have this weld eliminated, as I did on my 42″ project, if the contractor can get the engineering clearance.
If you have D1. All the other waterlines I worked required a 1″ unlimited overhead and vertical weld test with backup strip, 4 side bends to D1. Good visual aewa appearance is alway appreciated but rarely nit-picked and not to the standards most pipeline or facility welders produce. So, am I right in the beleif that the onsite inspector can interpret this at his discretion? It is essentially AWS Awwz. Don’t know if this is the latest or your applicable Edition, but By Cactusthewelder Date There are several guys on this forum with such experience who might be looking for work, I’ve heard most of their work is slow untill after the new year so they wwwa be available.
The best welders on that line welded that joint in a 10 hour day and inspection was stringent. Nebraska – Section Generically speaking, my experience with AWWA is that it doesn’t have a lot of teeth. By Superflux Date Nevada – Section I’ve worked 5 large bore waterlines as a rig f206, one 42″ short line I contracted myself, so I have some experience but there are others who specialize in that niche and can speak more authoritavely than myself.
Anyone know the AWWA c code ?
Of c26, every inspector will have their say in intrepretation of this code. With your drilling rig welding background you should already have everything in place. I am neither an engineer nor a CWI, but I make the point on a job to either be conversant in the code expectations for the welding I will be doing or to learn them PDQ.
By awsa Date They refered everything to the welding inspector. Colorado – Section This standard describes field welding of three types of circumferential pipe joints: Welding the inside lap joint on a 36″ line would not be a job I would care to volunteer for, at least not for an extended period of time- it gets a little cramped in there awsa me.
It essentially refered all questions of code compliance to the D1. If RT is used When will they learn?!?
