Don’t know if this is the latest or your applicable Edition, but When requested by the purchaser, a full-time welding inspector shall be present whenever there is welding to be done. This standard describes field welding of three types of circumferential pipe joints: On a 20 mile 42″ line I rig welded on with the frew requirements the welding contractor had me qualified with a a full pen 5P, 6″, 6g qualification examined to D1.

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

Generically speaking, my experience with AWWA is that it doesn’t have a lot of teeth. The best welders on that line welded that joint in a 10 hour day and inspection was stringent. Vree 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.

Awwa C206-17 Field Welding of Steel Water Pipe

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. By yojimbo Date Good visual weld appearance is alway appreciated but rarely nit-picked and not to the standards most pipeline or facility welders produce. Welding of gasketed joints may require modification to the parameters of this welding standard. 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.

Anyone know the AWWA c code ?

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. If RT is used 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.

Nebraska – Section By dbigkahunna Date That pretty much answered my question and my curiosity. By Superflux Date 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.

The aqwa, while not lax, takes very little responsibility for self-definition. Rochester – Section awsa North Florida – Section May want to go over your continuity logs to be sure everyone is current. If you have D1. Something to chew over maybe anyway. It is possible to have this weld eliminated, as I did on my 42″ project, if the contractor can get the engineering clearance.

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 awwq a few of the essentials like but strap fit ups.

All the other waterlines I worked required awda 1″ unlimited overhead and vertical weld test with backup strip, 4 side bends to D1. With your drilling rig welding background you should already have everything in place.

By rfieldbuilds Date It also list the welds to be performed with 70xx. Aqwa the inside lap joint on a 36″ line would not be a tree I would care to volunteer for, at least not for an extended period of time- it gets a little cramped in there for me. Puget Sound Olympic awaw Section Not logged in American Welding Society Forum.

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. 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.

Again not rocket science, but I hate seeing guys re-inventing the wheel.
