Is that even possible? How would one isolate big pipe under such great pressures?
- DyslexicAtheist 11y agoit is possible: https://en.wikipedia.org/wiki/Hyperbaric_welding https://en.wikipedia.org/wiki/Hyperbaric_welding there are many reason one might want to consider it but usually it is easier to do a quick fix with a wet weld and then plan on a bigger project to get the structure out of the water. only when this is too costly or impossible would they do a hyperbaric weld.
- mchahn 11y agoThe golden gate bridge and many others were built by working in dry "bubbles". An inverted dome on the sea floor was filled with air so the workers could work on the seafloor pretty much the same as on the ground outside. I don't know how they worked under that air pressure. I guess they had to decompress like any diver.
