You're thinking of factory welding, manufacturing or maybe repetitive pipeline welding and thinks like that.
It'll be a while until a robot disassembles a trailer enough to remove the bent axle, cleans off all the paint and rust, bends the trailer back into shape where needed, cuts a custom support to makeup for some lost strength, welds it in, primers it, paints it, and assembles the trailer.
Same for construction too.
If automation excels sufficiently, robot will replace bent axle with new one automatically, repair cost will be usually higher than replace cost if all things are automated
The axle gets replaced even today. The thing we were welding was the frame.
Will it tho? I wonder. We're on the brink of a robotic revolution.
