By rfieldbuilds Date Other welding required in field fabrication and installation of specials and appurtenances is also discussed.

By dbigkahunna Date Of vree, every inspector will have their say in intrepretation of this code. 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. Water work is generally IMHO far less critically challenging, but every application in this trade has its tricks, short cuts and learning curve c26 I thought I might pass on the few crumbs I’ve gleaned from my limited time in those particular trenches.

Again not rocket science, but I hate seeing guys re-inventing the wheel. When requested by the purchaser, a full-time welding inspector shall be present whenever there is welding to be done.

Good visual weld appearance is alway appreciated but rarely nit-picked and not to the standards most pipeline or facility welders produce. Nebraska – Section Rochester – Section The code, while not lax, takes very little responsibility for self-definition. It is possible to have this weld eliminated, as I did on my 42″ project, if the contractor can get the engineering clearance. Powered by mwForum 2.


Florida West Coast – Section San Francisco – Section 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 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.

Puget Sound Olympic – Section May want to go over your continuity logs to be sure everyone is current. 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.

By yojimbo Date 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.

The design of field-welded joints is not described. Colorado – Section 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.

By Superflux Date The best welders on that line welded that joint in a 10 hour day and inspection was stringent. Not being familiar with the accept reject to D1. Arizona – Section If you have D1. If RT is used 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

Looks to me the welding falls under D1. Generically speaking, my experience with AWWA is that it doesn’t have a lot of teeth. It will typically refer to D1. All the other waterlines I worked required a 1″ unlimited overhead and vertical weld test with backup strip, 4 side bends to D1.

We will be doing a 36″ waterline and that is the only code that is implied on the drawings. Not logged in American Welding Society Forum. Don’t know if this is the latest or your applicable Edition, but My IOR was clueless about welding.

I have never seen a xray rig on a water job, but I have yet cc206 work 2c06 one. It required freee 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 did initial inspection and follow up inspection after they allowed repairs to parts that didn’t line up with their pumping station. North Florida – Section 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.

Nevada – Section
