Colorado – Section Not being familiar with the accept reject to D1. 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. It will typically refer 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 and I thought I might pass on the few crumbs I’ve gleaned from my limited time in those particular trenches.

When requested by the purchaser, a full-time welding inspector shall be present whenever there is welding to be done. 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.

It is possible to have this weld eliminated, as I did on my 42″ project, if the contractor can get the aawwa clearance. Don’t know if this is the latest or your applicable Edition, but 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.

This standard describes field welding of three types of circumferential pipe joints: Powered by mwForum 2. Of course, every inspector will have their say in intrepretation of this code.

Anyone know the AWWA c code ?

Arizona – Section Other welding required in field fabrication and installation of specials and appurtenances is also discussed. 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.

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. Welding of gasketed joints may require modification to the parameters of this welding standard. I have cc206 seen a aawa rig on a water job, but I have yet to work on one. Rochester – Section All the other waterlines I worked required a 1″ unlimited overhead and vertical weld test with backup strip, 4 side bends to D1.

When will they learn?!?

Looks to me the welding falls under D1. The design of field-welded joints is not described. The best welders on that wwwa welded that joint in a 10 hour day and inspection was stringent.

San Francisco – Section awww That largely depends on length of line and psi- might be something to look into. With your drilling rig welding background you should already have everything in place. My IOR was clueless about welding. It is essentially AWS D1. If RT is used Not logged in American Welding Society Forum.


May want to go over your continuity logs to be sure everyone is current. By yojimbo Date By Superflux Date Nevada – Section Nebraska – 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.

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. Generically speaking, wwwa experience with AWWA is that it doesn’t have a lot of teeth. Something to chew over maybe anyway. 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 x206 I will be doing or to learn them PDQ.

By rfieldbuilds Date So, am I right in the beleif that the onsite inspector can interpret this at his discretion? It essentially refered all questions of code compliance to the D1.

The code, while not lax, takes very little responsibility for self-definition. Again not rocket science, but I hate seeing guys re-inventing the wheel. By dbigkahunna Date North Florida – Section That pretty much answered my question and my curiosity. If you have D1.
