    looks more like a bio-pharm type of gas, dunno about welding.

    if i read the whole sheet on it, i would have seen that its a flammable gas, so most likely NOT a shielding gas

      I think Scotty uses it when the wrap drive runs out of dylithium crystals.

        You can gas weld with hydrogen and it seems similiar but super expensive. I didn't really think it was for welding just curious what folks would say it's for.

          It's used for a variety of things. It is an isotope of hydrogen with a single neutron. Most hydrogen (much more than 99%) has no neutron in the nucleus-- only a proton. Deuterium is chemically the same (in most processes) as normal hydrogen, but can be identified by the greater weight of the atom, usually using a mass spectrometer. It's used in chemical synthesis, in nuclear research (the neutron changes the nuclear cross section dramatically), and in a number of other places.

          The place I have seen it was in making up tracers when I was working in the medical research lab. They would use deuterium in synthesizing a compound, and where the deuterium ended in a biological process that involved the compound, it told them about how the process worked. For example, if you replace a hydrogen at one end of a five-carbon linear hydrocarbon, like pentane, and the deuterium shows up in a bacterium growing exposed to it, you have evidence that the bacteria is taking hydrogens from the end of the molecule.

              Sounds like something that would require permits or license to handle or some sort of paper trail.

                pro,

                No, that's methane that normally requires a "paper trail".
