If you have 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. They refered everything to the welding inspector. It essentially refered all questions of code compliance to the D1. Don’t know if this is the latest or your applicable Edition, but By Superflux Date On a 20 mile 42″ line I rig welded on with the 70XX requirements the welding contractor had me qualified with a a full pen 5P, 6″, 6g qualification examined to D1.

I would say though, if I was going to contract a decent sized large bore waterline, and especially if I was not going to self perform or be able to be onsite for its daily managment, I would absoutely recruit a guy with experience and expertise as a lead man to oversee and train the welders in a few of the essentials like but strap fit ups. It also list the welds to be performed with 70xx. I did initial inspection and follow up inspection after they allowed repairs to parts that didn’t line up with their pumping station.

San Francisco – Section Nebraska – Section With your drilling rig welding background you should already have everything in place. Something to chew over maybe anyway. Other welding required in field fabrication and installation of specials and appurtenances is also discussed. Florida West Coast – Section If RT is used That largely depends on length of line and psi- might be something to look into.

Puget Sound Olympic – Section Good visual weld appearance is alway appreciated but rarely nit-picked and not to the standards most pipeline or facility welders produce. My IOR was clueless about welding. This standard describes field welding of three types of circumferential pipe joints: As I have recently completed inspection on a storm water pumping station with AWWA listed as the awqa code, I will say I was suprised that the code offered little guidance.

Nevada – Section When requested by the purchaser, a full-time welding inspector shall be present whenever there is welding to be done. Welding the inside lap joint on a 36″ line would not be a job C2006 would care to volunteer for, at least not for an extended period c20 time- it gets a little cramped in there for me.

Anyone know the AWWA c code ?

Welding of gasketed joints may require modification to the parameters of this welding standard. Looks to me the welding falls under D1.

Rochester – Section All the other waterlines I worked required a awws unlimited overhead and vertical weld test with backup strip, 4 side bends to D1. It is possible to have this weld eliminated, as I did on my 42″ project, if the contractor can get the engineering clearance. 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 I was good to go.

So, am I right in the beleif that the onsite inspector can interpret this at his discretion?

Awwa C Field Welding of Steel Water Pipe : American Water Works :

Not logged in American Welding Society Forum. It will typically refer to D1. Generically speaking, my experience with AWWA is that it doesn’t have a lot of teeth.

By Cactusthewelder Date When will they learn?!? 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.


There are several guys on this forum with such experience who might be looking for work, I’ve heard most of their work is awqa untill after the new year so they migh be available. North Florida – Section 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 others who specialize in that niche and can speak more authoritavely than myself.

Awwa C206-17 Field Welding of Steel Water Pipe

He swears by it, as you know, most rig welders prefer to avoid wire. Colorado – Section Not being familiar with the accept reject to D1. I have never seen a xray rig on a water job, but I have yet to work on one. Again not rocket science, but I hate seeing guys re-inventing the wheel. 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 ffree crumbs I’ve gleaned from my limited time in those particular trenches.

Arizona – Section May want to go over your continuity logs to be sure everyone is current. That pretty much answered my question and my curiosity. We will be doing a 36″ vree and that is the only code that is implied on the drawings. 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. Powered by mwForum 2.
