Good visual weld appearance is alway appreciated but rarely nit-picked and not to the standards most pipeline or facility welders produce.

He swears by it, as you know, most rig welders prefer to avoid wire. Florida West Coast – Section If RT is used I have never seen a xray rig on a water job, but I have yet to work on one. 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. By yojimbo Date 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 fre 70XX requirements the welding contractor had me qualified with a a full pen 5P, 6″, awsa qualification examined to D1.

Something to chew over maybe anyway. Other welding required in field fabrication and installation of specials and appurtenances is also discussed. They refered everything to the welding inspector. The code, while not lax, takes very little responsibility for awaw.

When will they learn?!? Puget Sound Olympic – 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.

Rree IOR was clueless about welding. 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.

Looks to me the welding falls under D1.

I did initial inspection and follow up inspection after they allowed repairs to parts that didn’t line up with their pumping station. It is essentially AWS D1. We will be doing a 36″ waterline and that is the only code that is implied on the drawings.

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. Again not rocket science, but I hate seeing guys re-inventing the wheel. It is possible to have this weld eliminated, as I freee on my 42″ project, if the contractor can get the engineering clearance. By dbigkahunna Date May want to go over your continuity logs to be sure everyone is current.
