What welding projects are you working on? Are you proud of something you built?
How about posting some pics so other welders can get some ideas?

Well Shannon, all I can say is that I'm sure impressed with the gargantuan size of this project. Some serious runs involved there boy.
How many rods / packets / lbs do you reckon were required to complete a full joint around the circumference including root passes and cap etc?
PS: I don't envy you having to fix the under-cut and the slag inclusion....

Sure is a beautiful day in your neighborhood!
In photo #4, what is the purpose of the 2" (or so) welds that are perpendicular to the main weld joint?

I am thinking they are left behind from bar that was welded on for lining up the two pipes.In photo #4, what is the purpose of the 2" (or so) welds that are perpendicular to the main weld joint?

In just welding the cans together there was 21 rolls of wire used. We still had to laminate some 2" thick plate for lifting eyes on the end sections (on the side of the cans) and lifting eyes on the top side of the cans.
What's you see is the reminence of welds where we placed the "dogs" on the cans to push and pull the joints around to get them to align.Artie F. Emm wrote:Sure is a beautiful day in your neighborhood!

What we use is a piece of 1" thick plate that is cut in the shape of an "L" with a 2" bolt that has the nut welded to the plate that is used for clamping and pushing force.weekendwelder70 wrote:I am thinking they are left behind from bar that was welded on for lining up the two pipes.In photo #4, what is the purpose of the 2" (or so) welds that are perpendicular to the main weld joint?
This one was with scarfing tip and a 8" grinder but I have had to use a air arc before.motox wrote:how are you planing on fixing those bad welds, girding?
Also keep in mind guys that cap pass is roughly 2" wide. LoL
Those cans are 30' long and we was making the five cans into two sections because the drilling company didn't get a large enough crane to lift it in one piece. (Each can weighed 48,000 lbs.)

Awright....
If I've got to scroll through 30+ pictures of your weldsto get to the point,
Here's a play on your topic title...

Shannon, what will the pipeline be used for?
Some serious capacity there...

Coal mine air shaft that just had a fire in a old works. This is just the surface casing. Once it's set and concreted in the ground they will drill another hole through that string of cans to shaft depth. Once they pop through we will start running 8' dia in the ground to the mine.TRACKRANGER wrote:Shannon, what will the pipeline be used for?

When it rains it will have enough air pushing out of the hole to suspend water in mid-air.

Which clamps did you use?
I always use chain clamps http://www.dwt-gmbh.de/en/pipe-chain-clamps.html but don't know if it's the best solution for that size

I don think that type of system would work for this size of pipe. I'll be going back to finish the job next week. When I get there I'll shoot some photos of the "dogs" we use.

I've always been impressed with the simple key plate, lug and wedge system used in building large tanks and welding sections of large pipe. Once installed you can use the wedges to either open or close the gap as you progress and change the alignment in and out.
The only downside is the fact that they need to have the key plate lug welded to the surface that will later need removed with a torch and grinder. This proves to be a little more troublesome when dealing with SS or Aluminum but in the age of the plasma cutter it is getting easier.

This is what we call a "dog". With this piece you can align your joint. The check marks on the outside of the cans that was asked about is where there was a dog welded on to get that joint aligned.CutKiller wrote:@shannon
that would be great, looking forward to it

That is what I call a "screw-dog". I also have "wedge-dogs", which are quite similar, only a wedge is driven where your threads and nut are. For plate work, I FAR prefer the wedge dog for speed and efficiency. For pipe work, the screw-dog can't be beat.

I also have "gap dogs", that I tack 120* apart on pipe to push/pull the gap to where I want it.

It's amazing the amount of pressure you can exert with that little bolt. But I've also had them pop off and bite me. Had three stacked tight and as soon as I felt the weld give on the one I was tightening I couldn't get away fast enought. Blew all three off and took one to the chest. Needless to say I don't crank on them to that point any longer. I just add more dogs to help distribute the work load over a larger area.Otto Nobedder wrote:That is what I call a "screw-dog".

This was the job I was dodging dogs. We cut the first can to get it to root gap right and after that every joint was a PITA to dog and we cut every can after that. Never heard if the can sequence got screwed up or if it was just a poopy string of cans.
