By rfieldbuilds Date I am neither an engineer nor a CWI, but I make the point on a job to fee be conversant in the code awaa for the welding I will be doing or to learn them PDQ.
It essentially refered all questions of code compliance to the D1. When will they learn?!? May want to go over your continuity logs to be sure everyone is current. Powered by mwForum 2. That largely depends on length of line and psi- might be something to look into. By Cactusthewelder Date 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.
Awwa C Field Welding of Steel Water Pipe : American Water Works :
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 yojimbo Date 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.
If RT is used Again wwwa rocket science, but I hate seeing guys re-inventing the wheel. So, am I right in the beleif that the onsite inspector can interpret this at his discretion?
Colorado – Section 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. Nebraska – Section That pretty much answered my question and f206 curiosity.
Awwa C206-17 Field Welding of Steel Water Pipe
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.
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 fre so they migh be available. I did initial inspection and follow up inspection after they allowed repairs to parts that didn’t line up with their pumping station.
Of course, every inspector will have ftee say in intrepretation of this code. I have never seen a xray rig on a water job, but I have yet to work on one. When requested by the purchaser, a full-time welding inspector shall be present whenever there is welding to be done.
By dbigkahunna Date We will be doing a 36″ waterline and that is the only code that is implied on the drawings.
San Francisco – Section It is essentially AWS D1. Frfe to me the welding falls under D1. They refered everything to the welding inspector. It will typically refer to D1. Something to chew over maybe anyway.
The design of field-welded joints is not described. With your drilling rig welding background you should already have everything in place. By Superflux Date If you have D1. Arizona – Section 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.
It also list the welds to be performed with 70xx. Welding of gasketed joints may require modification to the parameters of this welding standard. Florida West Coast – 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.
The best welders on that line welded that joint in a 10 hour day and inspection was stringent. All the other waterlines I worked required a 1″ unlimited overhead and vertical weld test with backup strip, 4 side bends to D1. Not being familiar with the accept reject to D1.
Good visual weld appearance is alway appreciated but rarely nit-picked and not to the standards most pipeline or facility welders produce.
