I did initial inspection and follow up inspection after they allowed repairs to parts that didn’t line up with their pumping station. I’ve worked 5 large bore waterlines as a rig welder, one 42″ short line I contracted myself, so I have some experience but there are ffree who specialize in that niche and can speak more authoritavely than myself. Of course, every inspector will have their say in intrepretation of this code. Florida West Coast – Section They refered everything to the welding inspector.
It is essentially AWS D1. So, am I right in the beleif that the onsite inspector can interpret this at his discretion? On a 20 mile 42″ line I rig x206 on with the 70XX requirements the welding contractor had me qualified with a a full pen 5P, 6″, 6g qualification examined to D1. Again not rocket science, but I hate seeing guys ftee the wheel.
Anyone know the AWWA c code ?
When will they learn?!? 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.
When requested by the purchaser, a full-time welding inspector shall be present whenever there is welding to be done. Don’t know if this is the latest or your applicable Edition, but Other welding required in field fabrication and awwaa of specials and appurtenances is also discussed.
Powered by mwForum 2. Something to chew over maybe anyway. This standard describes field welding of three types of circumferential pipe joints: 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 migh be available. 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. It will typically refer to D1.
That pretty much answered my question and my curiosity. May want to go over your continuity logs to be sure everyone is current. It required the voltage module to be installed on my Classic D, which I wasnt going to spend for, so he by passed the code wth charpy testing on my weld test and Awsa was good to go.
He swears by it, as feee know, most rig welders prefer to avoid wire.
Awwa C206-17 Field Welding of Steel Water Pipe
With your drilling rig welding background you should already have everything in place. By dbigkahunna Date North Florida – Section By yojimbo Date Generically speaking, my experience with AWWA is that it doesn’t have a lot of teeth. San Francisco – Section Colorado – Section Good visual weld appearance is alway appreciated but rarely nit-picked and not to the standards most pipeline or facility welders produce. 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.
My IOR was clueless about welding. The best welders on that line welded that joint in a 10 hour day and inspection was stringent. Nevada – Section 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 Cactusthewelder Date I have never seen a xray rig on a water job, but I have yet to work on one. 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.
That largely depends on length of line and psi- might be something to look into. 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 for me.
Not logged in American Welding Society Forum.
Rochester – Section Puget Sound Olympic – Section It also list the welds to be performed with 70xx. Nebraska – Section Looks to me the welding falls under D1. The design of field-welded joints is not described. We will be doing a 36″ waterline and that is the only code that is implied on the drawings.
