Robotic Plasma Gouging and MIG Welding Cylindrical Stators

Here was our very first cell. We had to weld these cylindrical stators (internal parts for an electric motor) while they were being clamped together by a hydraulic cylinder pulling with 50,000lbs of force. The stators weighed up to 2.5 tons, and diameter was infinitely variable between 8" to 30", and up to 50" high. First, we use laser sensors to detect the height and diameter of the stator, then we had to use plasma torches to gouge notches in the cylinder, then used MIG torches to weld them together. The reason for the welds to be vertical was that these stators (up to 30" in diameter and up to 50" tall) were made up of rings of metal (more like disks I guess) that were about 1/32" thick and were stacked up to make the full height of the stator.

Very nice video! Beautiful! With this music, that reminds me a ballet! Who say industry cannot be artistic?

yeah, great game and one of the best soudtracks for a game ever made. Surprising what they did with SNES sound...

Nice Chrono Trigger music.

Yes they are, and they're still going strong!

Those Kuka?

The center thing is described in the Video Description. It's the stator (inside electrode assembly) of a large electric motor. The stator is made up of thin plates, about 1/16" thick that are punched out and stacked up to the right height. After they are welded, they are wound with wire and assembled.

It was going through a dry run of the gouging/welding process. First, it checks the laser sensor, then it scans the part for dimensions, then it Plasma Gouges (Simulated in this video), finally it MIG Welds.

what it doing anyway and what with the center thing ???
