A new high-speed X-ray video camera, now the fastest in the world, can see through molten metal and watch weld-weakening flaws form in real-time.
The $670,000 device successfully captured X-ray footage on Nov. 23 at 5,000 frames-per-second (fps), or five times faster than previous X-ray cameras (and 83 times faster than a consumer camcorder). The high-speed video above shows a laser welding solid aluminum in visible light, followed by the new X-ray-light welding clips.
â€œWith visible light, we could only see the surface of the welding process. You couldnâ€™t see what was happening inside,â€ said Felix Abt, one of the cameraâ€™s designers at the University of Stuttgart. â€œThe only way to see pores that weaken weld seams was to cut the metal into pieces.â€
Watching that thing is... hypnotic
