Wow. In this case even more useful than welding would be! I wonder what is the final product though...

It is more then welding, this joiont is stronger then the whole object. the movement even made a permanent magnetic connection, by lining up al matal atoms one direction. both sides, before they melted together

Looks like a pulley for a giant crane or something like that , or maybe some kind of roller bearing

This is better and good straight joint, a normal welding will cause metal parts to pull to side and not very accurate.

I've just welded my cock to my hand with the power of friction. Maybe next time I'd better use some lube

that is a carrier roller for the bottom of a bulldozer,crane,excavator.Any track driven machine. Follow this link,it has a nice close up at :24 sec of the 6 carrier rollers with the spindle and bearings installed.

Neat technology like this isn't always new either, most people just haven't seen it before. I think this goes back a long way in industrial history.

I never heard of such a thing as friction welding but once you've seen it you realise what a simple and clever idea it is.
