It has been claimed/stated, somewhere that I stumbled across but can't now find, that long periods in space tend to weld metal moving parts together so that they no longer function. So I ask: is this true, and if so is it why the ISS needs so many maintenance spacewalks? And leading on from that, why is Merlin so convinced that it hasn't happened to the dreaded bombardment station?

Because Merlin also knows about possible automated maintenance systems that were available to the TF at the time of Operation Ark. Given that the Textev points to PICA construction being a matter of materials and construction-programmed nanites, I can easily imagine that the Temple and the OBS are both maintained with nanites crawling throughout their systems, replacing defective molecular circuitry, building replacements
in situ, dumping the damaged components into recycling devices and collecting new raw materials from throughout the Kau-zhi System. If critical systems had broken down before without similar repairs, any competent member of the command crew would have taken the precaution of setting an emergency "wake up procedure" to fix said critical system.
