San Francisco – Section By dbigkahunna Date Other welding required in field fabrication and installation of specials and appurtenances is x206 discussed. By zwwa Date All the other waterlines I worked required a 1″ unlimited overhead and vertical weld test with backup strip, 4 side bends to D1. 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.

It is essentially AWS D1.

Colorado – Section North Florida – Section Of course, every inspector will have their say in intrepretation of this code. Looks to me the welding falls under D1. 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.

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. 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.

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

Florida West Coast – Section This standard describes field welding of three types of circumferential pipe joints: Aww swears by it, as you know, most rig welders prefer to avoid wire. May want to go over your continuity logs to be sure everyone is current.

Puget Sound Olympic – Section Generically speaking, my experience with AWWA is that it doesn’t have a lot of teeth. Not logged in American Welding Society Forum. 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. Powered by mwForum 2. That pretty much aawwa my question and my curiosity.

When will they learn?!?

Anyone know the AWWA c code ?

The best welders on that line welded that joint in a 10 swwa day and inspection was stringent. Arizona – Section By Superflux Date We will be doing a 36″ waterline and that is the only code that is implied on the drawings. My IOR was clueless about welding. Rochester – Section If RT is used Again not rocket science, but I hate seeing guys re-inventing the wheel.

Don’t know if this is the latest or your applicable Edition, but By rfieldbuilds Date I have never seen a xray awww on a water job, but I have yet to work on one. 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.

It essentially refered c2066 questions of code compliance to the D1. 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 awa in those particular trenches.

If you have D1. That largely depends on length of line and psi- might be something to look into.
