One place I worked did a lot of sub arc pipe spools. Was
impressive runs going in on occasion

the
pipe was rotated and the weld pool always on top so not overly positional
used to work for a guy who's biz was partly to do with the local steel works round here ... amongst all sorts, he re-furbished the Davey mill rollers from the rolling mill lines.
subby arc rebuilding of the wearing surfaces ... could put down a 12mm thick layer about 35mm wide in a pass ... rolls were rotated under the weld heads in heated environments and once rebuilt enough, machined back to tolerances ..
could swing up to 40 t in the biggest of their lathes ... a new Poreba, which I had the pleasure of helping to install and commission with the Polish guy who came over to oversee the installation and commissioning ...
used to turn my hand to all sorts for Dennis ... and often floated about filling in if someone hadn't turned in ... and ran the subs more than the odd occasion .... had to be on the ball with them ... inclusions didn't go down too well and were a right faff to sort out
learnt a hell of a lot there and got to do all sorts of things, especially as he trusted me enough to get dropped onto all sorts of different things ... was never boring for sure ... was a great experience.
