cool now perform a repair on something inside of it.
These are structural components that don't have anything "inside" but are used as material for carrying/distributing loads, and their strength and weight is the thing that matters. If their integrity is compromised, you generally don't repair structural components if the repaired seam wouldn't have the same strength as the original material, but replace them.
That said, I can imagine it being good for applications like fighter jet components where it's probably considered scrap after the first accident.
There is no need to do so. You would replace the part.
Objects in the industrial world can’t be repaired. But Titanium can be melted.
Most hair dryers don’t come with parts manuals so we wouldn’t know exactly which replacement part to get. And there’s more to it like a switch, a cord, etc. These things could be designed for repair but they would have to provide reliable part numbers for the internals, which they currently do not do.
> Objects in the industrial world can’t be repaired.
Objects in the industrial world most certainly can be repaired and it happens all the time. For example here is how a giant excavator tire is repaired:
That makes no sense to me, as industrial things commonly are repaired. Sometimes many times across decades as one part or other wears.
Replacing parts is not repairing from that point of view, even if at a macroscopic level it returns something back to working condition.
Also, why did "replacing parts" suddenly spring up?
"Repairing" something is generally considered to be taking whatever action is needed to get it back to the required condition. If some parts need fully replacing, then so be it.
But it could just also be things needing to be re-seated, maybe something needs to be bent back into shape, etc. The list of possibilities is probably endless.
