We’ve seen a lot of welding in our day, but this is just mesmerizing. It’s extremely interesting to watch, and you’ll probably click the replay button!

We tried to find information regarding what exactly is being made in this video, but never found an exact answer. Some claim it’s a truck wheel, or some sort of pulley, but we’re still not sure! The machine simply uses friction to weld the two objects together in a matter of seconds. If you know anything about what’s actually being welded in the video let us know! Is this stronger than conventional welding? What other uses are there for this?
