    Welding on Star Trek

    I’ve been a fan of Star Trek since it started.

    Now, why do they insist on stick welding . Metals like tri tanium and unobtanium are hard enough to weld in the aerospace industry, but, come on in a vacuum? Yes tig welding and laser welding work well in vacuum. Out on the hull in the shade would make the materials subject to vast differences in temps. Almost every exotic metal alloys have temp sensitivities well defined. I surely don’t know all of them . I have not attempted stick welding in high vacuum but my guess is it would not be easy if at all.

    How about some fun comments.

    Because Scotty is a crusty old bugger and they will have to pry his stick stinger from his cold dead hand, and even then he won't give it up just like some of us here.

    Re: Welding on Star Trek

    You can easily stick weld in a vacuum,, just like tungsten,, or wire.

    With each process, just weld and go,, no coating is needed on the wire to stick weld,, no gas for tungsten, no gas or flux for wire.

    Outer space is like 10 to the minus 9 torr or better,, (that is a pretty low vacuum)

    {I used to oversee a vacuum furnace, it was a 10 to the minus 6 torr vacuum.
    At 10 to the minus 6, put a piece of 304 stainless steel in the furnace,, heat it to 1800 degrees F. ,,,
    when it comes out, any oxide discoloration on the part is reduced back to metal, the oxide is gone.

    We heat treated contactor frames for mine sweepers.
    the stainless had to be annealed to remove any stress put into the part when the stainless steel was formed.

    Non magnetic stainless steel (304) becomes slightly magnetic when the steel is bent.}

    It would be cool,, arc welding with 1/8" uncoated rod,, and get a perfect weld.

    So, Scotty probably grabbed a few coat hangers ,, nipped them at the bend, and ran outside,
    and patched the hole the Klingons had just blown in the ship,,

    NOTE: the coat hangers are made out of the same unobtainum as the ships hull,, to save weight,,

    You can tig weld in a vacuum? What conducts the current from tungsten to workpiece?

    yes you can. the spark will jump even more easily from tungsten to part.

    It is set roughly in the 2260s

    the show aired 1968

    292 years had passed since the Welding technology in 1968>

    1968 was like being in the 1670's in relative time/technology.

    You can not see it in the picture, but, Scotty is holding his phasor in his other hand,, one of the few times it was not set to "stun"
    Instead, the phasor is set to "weld"

    Isn't a high-voltage spark (like with the HF start) different from when lots of amps of current are going across the gap?

    I always thought that for current to go across the gap, you need plasma, and for plasma you need ionized gas (argon) but in a vacuum, you don't have gas...and therefore, no plasma.

    Now that I think about it, don't you also need plasma even for a spark to cross a gap ... like with lightning? With a spark plug, I believe the air actually gets ionized into plasma. Where's Louie? He ought to know about this...

    Re: Welding on Star Trek

    Everybody knows that the hull of the Enterprise was thermally controlled to maintain temperature, so the shade wouldn't cause a problem. That's the only way they could be sure it would be at the correct temperature for maximum impact resistance. I thought everybody knew that?

    I suspect the stick welding thing was a sham to put on a show for the bad guys rather than reveal the fact that the hull material could have replacement sections grafted in place...sort of self-healing with a patch to get it started.

    On second thought, I guess my theory doesn't account for vacuum tubes too well, does it?

    All I know is yrs ago they came out with vacuum contactors to to start 3 phase motors drawing high amps. Those contacts didn't travel far in relation to the old style open air contactors.

    Re: Welding on Star Trek

    You'd have to have some sort of shielding gas for MAG welding in space... you need an active component in the gas
    MIG of alloy and TIG welding would be fine... especially TIG where gravity isn't so important.

    Stick would struggle I believe... you want that flux gas not just for shielding, but for putting goodness into the base metal. The steel in stick rods is usually billy-basic, it's the coating that gives it small amounts of other elements to give it the strength. So I'm sure you'll get an arc, but the welds might be weak and full of porosity.

    Of course, Scotty uses laser or electron-beam welders. Point and zap.

    I love this sort of inane conjecture.

    I see he's got his space-welding contact lenses in.

    Or maybe just his safety squints.

    I’ve been stocking up on dilithium crystals for quite a few years.

    When space welding becomes popular I am going to be a very wealthy man.

    Re: Welding on Star Trek

    This is what I imagine.....

    All welding processes will be accomplished with personal devices such as smart phones or phasers in the near future.

    The hot topic on Welding Web will be shaming users for buying alternate universe (HF of the future ) low powered devices in favor of “ Make Earth Great Again” personal welding devices. The insults will begin.

    Horror stories will abound with warranty shipping issues to Uranus. ( no offence Samm)

    Former prominent contributors on the Political Forum will opt to take extended stress leave when they realize the true extent of “inclusivity” when it applies to interplanetary life forms.

    Moto “sees the light”, invests heavily in respiratory helmets and becomes rich when they are deemed necessary for interplanetary travel.

    That’s a little different.
    Cathode has to be electrically heated. Current flows
    with no arcing involved. Little or no heat CREATED.
    I don’t think they’d be doing any welding that way.

    Jet arcin is one of my favorites believe it or not...most guys hate it...I love it...somethin must be wrong with me because it seems like evrything i enjoy doin most evyone else avoids like the plague or covid.

    Same way with work in general, I like what I do, most the other guys grumble mumble piss and moan about it, I get there at 5am or 530 or so and just jump right in, they are still rubbin their eyeballs and sippin coffee at 6am tryin to decide if they really wanna do this today. It just what I do and the way I was brought up

    When it comes to jet arcin I like the noise i like the sparks and if it somethin i dont need to be fussy about i just crank that ol 502d up and leterrip.

    If i gotta be fussy I can do that too.
