I think there should be a category of &quot;there I fixed it&quot; just for over zealous welders. I worked with a robot that had an aluminum tool that got mangled every time the robot got in a fight with the lift table. This was a Kuka 450 (as in kg), and it could really stack. A maintenance guy thought it was an enormous chore rebuilding the tool each time, so he bolted (literally) a 3&#x2F;8 inch steel plate to the thin aluminum a frame. And when that tore welded the whole shebang. Next time the robot snapped its wrist, since the tool could no longer buckle and absorb the impact, and it rather impressed the service engineer with the... sturdiness of the tool.<p>I wanted to share the story about environmental&#x27;s efforts to put gas meters on the safety release valves on our large liquid argon dewars, but we thankfully convinced them that accidentally blowing a crater in the plant was a worse OSHA  violation than upsetting our local regulators. (An accident in a nearby county with a truck hauling liquid gas dewars resulted in a death by displacing all the air in the intersection with Argon, leading the inert gas to be classified as a dangerous controlled substance that needed to be monitored and metered...)
