Cold welding occurs when two metal pieces in vacuum touch and bond without heat or adhesive. In space, the lack of oxide layers allows atoms to merge, causing mechanisms to seize. The phenomenon was problematic, for example with the Galileo satellite antenna that never opened. Engineers solved it by using non‑bonding metal pairs or special coatings. Today, cold welding is harnessed for repairs on the ISS and in nanotechnology, turning a once‑dangerous quirk into a useful tool.
