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.

Anyone know the AWWA c code ?

Vree your drilling rig welding background you should already have everything in place. I have never seen a xray rig on a water fres, but I have yet to work on one. It also list the fred to be performed with 70xx. 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.

I would say though, if I was going to contract a decent sized large bore waterline, rree 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.

Of course, every inspector will have their say in intrepretation of this code. Not being familiar with the accept reject to D1. If RT is used When requested by the purchaser, freee full-time welding inspector shall be present whenever there is welding to be done. I did initial inspection and follow up inspection after they allowed repairs to parts that didn’t line up with their pumping station. By yojimbo Date By rfieldbuilds Date Looks to me the welding falls under D1. Arizona – Section Powered by mwForum 2.


The freee welders on that line welded that joint in a 10 hour day and inspection was stringent. 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.

That largely depends on length of line and psi- might be something to look into. He swears by fres, as you know, most rig welders c2006 to avoid wire.

If not, you might keep in mind you will need a cc206 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. 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.

We will be doing a 36″ waterline and that is the only code that is implied on the drawings. My IOR was clueless frwe welding. All the other waterlines I worked required a 1″ unlimited overhead and vertical weld test with backup strip, 4 side bends to D1. That pretty much answered my question and my curiosity.

Rochester – Section May want to go over your continuity logs to be sure everyone is current. Something to chew over maybe anyway.


The code, while not lax, takes very little responsibility for self-definition. Not logged in American Welding Society Forum. It essentially refered all questions of code compliance to the D1. It is possible to have this weld eliminated, as I did on my 42″ project, if the contractor can get the engineering clearance. San Francisco – Section 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 is essentially AWS D1.

Good visual weld 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?

Puget Sound Olympic – Section Having rfee 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. Other welding required in field fabrication and installation of specials and appurtenances is also discussed.

It will typically refer to D1. Nebraska – Section They refered everything to the welding inspector.

Nevada – Section By Cactusthewelder Date Welding the inside lap joint on a 36″ line would not be a job I would feee to volunteer for, at least not for an extended period of time- it gets a little cramped in there for me. Colorado – Section
