Normally cast metal parts shouldn’t have issues detectable with optical inspection system. I worked for a company doing welding inspection systems. It is absolutely crazy when such part ends in the final product. This company clearly overstretched cutting corners on this.

Would a part like this get x-ray inspected? I had a summer job working at a machine shop and structural castings would often get sent for x-ray inspection.

It’s the best way and most expensive. For mass production of automotive parts probably too expensive. I mean these guys can’t or don’t want to afford 20000$ camera system for quality assurance.

Definitely not too expensive for automotive parts. Cast wheels are often 100% X-Ray inspected already. This is purely a lack of proper quality control systems.
