Is there a functional difference? Would cracks from a cold shut not disqualify the product (whatever it is) from going into service?

- padjo 3y agoI think it’s safe to say cracks in a structural member are always bad. I think the point the OP is making is that it looks like a manufacturing defect not the result of a crash.
- gaze 3y agoAny sort of defect like this should disqualify the product. It’s embarrassing and alarming that this casting wasn’t scrapped.
- contingencies 3y agoIt seems they have no automated optical inspection (AOI) system. Why? Theories. (1) Manufacturing site footprint availability. AOI on large assemblies with high throughput requirements may be extremely spatially and temporally inefficient as the need to control lighting means a substantial facility footprint may be required. (2) manufacturing operation build time pressures (3) assessments and claims by the casting equipment provider (4) the potential unavailability of an off the shelf solution suitable for parts of this scale. Stable process control could eliminate the need, but AOI is relatively cheap insurance.
- gaze 3y agodo you _really_ think this is a technical issue?
- contingencies 3y agoNo it's clearly an alien conspiracy. You're right.
- gaze 3y agolol woosh
- short_throw 3y agoIt's still a serious structural defect. The importance of the distinction here is that Tesla can't argue the customer caused this...a cold shut can only happen at casting time.
