Two of my clients make vessels - or at any rate, one makes the vessels aand th eother supplies them with the dished ends! One's in Bradford and the other in Clones, Co. Monaghan.
To make the bigger dishes they weld plate together then dish it; they x-ray the welds to ensure they're kosher before forming commences.
The vessels are made by welding plates together then rolling the whole thing into a cylinder before the dishes are welded on (think road tanker bodies).
The circumferential welds are then x-rayed by wrapping a (long!) length of film around the outside of the weld, setting up a panoramic x-ray head dead-centre inside the tank and nuking the whole weld in one pass.
I make sure the x-ray machines can show the defects they're looking for
Over the years the major problem was that the guys would trip whilst wrestling the x-ray heads through the man-access holes in the tanks and drop them; at £15K a pop it soon eats the profits of the job
