    If metals do not 'weld' on earth then how do two metal pieces conduct electricity when they are brought in 'contact' ?

    Yes. i know, cold welding in space. But it wont be the method used for large scale construction in space, if all you did was put two surfaces together you will still have a lot of tiny gaps, no surface is never perfectly flat down to the atomic scale. it would not be a strong joint. you will not pass a CWB bend test by cold welding. i guess a video i would have loved to see is how such hot welding could be done in space, with spatter, the lack of atmosphere, shielding gas, space suits, etc

    If you guys are interested you can check out friction stir welding. Friction stir welding transforms the metals from a solid state into a "plastic-like" state, and then mechanically stirs the materials together under pressure to form a welded joint. It doesn't use gas or a shielding gas. Making FSW small enough to fit in the cabin would benefit greatly.

  • Ricardo Pesenti
    Ricardo Pesenti Месяц назад

    Yeah, legit. Metallic bonds are very different from ionic and atomic bonds. The atoms are in a structure with an electron cloud surrounding them.
    so whitout oxide layer and when two metal surfaces perfectly touch one another whitout any unperfection, two metalls will weld.
    But since the contact needs to be perfect whitout any gaps or dirt, that's no big problem :)

    Not every metal forms an oxide layer. you should have specified that. The way you explained it makes it sound like this happens to every metal in an atmosphere of oxygen. If this were the case, you wouldn't need a vacuum to cold weld, but only an atmosphere devoid of oxygen like an inert atmosphere of Argon. Also, Richard Feynman talked about cold welding in his lecture series from 1964, 1 year before Gemini IV. So they had to have been aware of the phenomenon at the time of the mission.

    You do not have melt metals to weld them it is just the easiest way to join large complicated pieces of metals- pressure does it too also brazing works- low temperature. Your ignorance of weld engineering is a lot.

    What was exactly "cold welded". Hinge? If so then what was play/tolerance of moving parts in room temperature? As far as I know in space You get much below zero, -100 degrees Celsius. In such temperature things change dimension, so hinges might stick.

    This is something all mechanical engineers encounter, in a vacuum or not - we call it "galling" (adhesive wear). Aluminum and stainless steel really tend to do it.

  • bluefmi
    bluefmi 6 месяцев назад

    "thermal shock as the satelite passed from HOT to cold areas" pressure can fuse items together. no need for vacuum (and high pressure produces heat). but i agree, clean surfaces will help the fusing
    "jammed momentarily" does "momentarily" sound like "small adherence" or like "fusing" to you?
    you shoud actually read carefully what you present. heat was clearly presented in the paper.
