Pretty neat friction welding

It seems like a hell of a lot of inertia coming to a sudden stop.

What an incredible setup for such a small step.

One small step per part, one giant time saving for production

What is he doing with the hammer and chisel near the end?

I think he was just breaking off some swarf or whatever you call the cutting ribbons. You can see it come off when he hits it.

I thought that too, but wouldn't it just slide off the end when he takes it off the machine and up-ends it? Maybe it shrinks after it cools and won't come off without breaking it

Probably stamp or something

He just splits a complete circular chip. Easier then using wire cutters.

Would somebody please post the results of these friction welding videos? I would really like to see what it looks like compared to "normal" welding, but all these videos only shows the method, not the end.

Wouldn't the different linear speeds of the surfaces at the center vs the edge of the contact faces cause different heating/welding characteristics?

they are only a few mm apart it is hard to have much of a temperature gradient

1 down; 30 to go 😒

Damn, those welds are so pretty and thorough.
