This popped up on Faceache this morning, short documentary vid on pipe welding/laying, quite interesting. Some odd looking PPE worn by the bitumen men.
think about them whenever I head north past Tinsley Viaduct.
what process...i cant see any welding headA guy I worked for developed and built an internal pipe welding machine, poor photo as scanned form a brochure.

It's the 'pipeline across the fens' video. Watched it many a time, I think it was co2 shielded solid wire root, stick hot/fill/cap. Lincoln gear, sae300's running the job. A French crew if I remember what I read over on ukwelderI wonder where it is. Looks like they were using Innershield and Cellulosic Stick so I assume Stick Root and then fill and cap with Innershield (Self Shielded Flux Cored Wire).
I was told there had never been a Pipeline in the UK or Europe welded with Innershield, in fact, as far as I know they were ALL welded with Sticks until the early 00's and since some have been solid wire and some have been Gas Shielded FCW.
So, even though the scenery and the people look European they may not be in Europe....Anyone know?
I dont think so. Theres no shroud on the torch....and as far as I know there had never been a MIG welded pipe until the 00s....and at that time it was all CO2 and MIG was classed as semi-skilledIt's the 'pipeline across the fens' video.

You can pick the pipelines out running south down the A90, there are two, by the markers at each field boundry. One Bp or was the other shell. St Fergus, down past Cruden Bay, then round the west side of Aberdeen, Netherley, Brechin, Balbeggie, and on down to the refineries.I can remember when they were doing the gas line from St Fergus. From the air you can follow the line of the pipe, as the transfer of gas through the pipe generates heat, and crops grow better along the line.
Im a bit baffled but it is before my time...I recall CO2 welding as being classed as semi-skilled so Im amazed at the Pipeliners allowing it..but like you say there is a bottle so what else could it be used for......I used to meet all the Foreman before big projects and discuss how many rods they would want and where to deliver them...in the days when Lincoln had a monopoly 5P/5P+ and HYPs or 70+ and there were never any welded with solid wire....later when some Italians got involved there were MIG welding but by then the equipemnet was much better and so were the gas combinations.They've got co2 on the rig, and the root was definitely put in with a semi-automatic process. But as you say, that doesn't look like a normal mig gun. The spatter characteristics look like solid wire short circuit transfer though, and it doesn't look too smokey.
Here's the text from the guys comment, sorry the screenshot was small:Im a bit baffled but it is before my time...I recall CO2 welding as being classed as semi-skilled so Im amazed at the Pipeliners allowing it..but like you say there is a bottle so what else could it be used for......I used to meet all the Foreman before big projects and discuss how many rods they would want and where to deliver them...in the days when Lincoln had a monopoly 5P/5P+ and HYPs or 70+ and there were never any welded with solid wire....later when some Italians got involved there were MIG welding but by then the equipemnet was much better and so were the gas combinations.
Its a mystery
PS that screenshot is too small for my eyes (until after the Op hopefully)....

Just to clear up a few points ....
This pipeline ran from Kingslynn to Peterborough via Wisbech..
Contractor was Lang Pipelines UK. with Entropose GTM France..
Welding with Mig bead and the rest celulosic downhill..
YES A MIG bead in those days ..it proved to slow and they reverted back to Stick downhill..
All done in 4 mths app.
Welders A Sergent. P Rushe . N Johnson.T Mcdonald.
C Farray. G Machin, Rooney, S Dolan, A Richie, P Musk.
and lots more ...
Some of us are still welding if thats anything to be proud of..
I WAS THERE
Bit like the bug-o or subsea-7 setups?Well you live and learn....Im suprised the Pipeliners allowed MIG especially in those days....Entrepose were trying to used MIG for years. There was a guy I often met who was working on an automatic jig...best not mention his name as it never worked (well to my knowledge).....They always had issues in the 6 oclock to 9 oclock.
That torch is a strange one for gas shielded though.

I live next to wytch farm, Jones construction recently put in a new sea water pipeline from the edge of Poole harbour up to the gathering station. That was tig root, dual shield all the way out with bugs. Some spool base stuff, some joints in the middle of the fields. It was a nice gig, they did it over the summertime
