Four metal working processes no one teaches you

I just found this and it blew my mind. I'm going to go try the lathe pipe swaging technique.

Thank's very much for sharing this process. I will make good use of this.

This was interesting to see. Particularly the forming.
I feel like when I’ve seen friction welding process instead of slow the rotating part down, the stationary part is either loosened or allowed to spin together once the metals have heated sufficiently to weld. In this case I was thinking one could loosen the tail stock chuck. Or maybe the amount of pressure is higher and it’s kept on as the spinning force is removed so the spinning part slows quickly…I’ve wanted to learn more about the friction forming processes but have never had a chance.

This is very practical useful information. Thanks for sharing
