A weld would ruin that microstructure.
I see the justification, you're right. My point though was if riveting (for whatever reason) is good enough for an aircraft, it's good enough for EV box. Sure welded box is even stronger, I'm not debating that. I'm saying bolted/riveted box while technically weaker, if done right, can be made stronger than you really need to contain the batteries in a car and safe in case of an accident. So it is a real *option* and I'd not rule it out just because welding also exist. Victor
