Its called "stir friction-welding".The welds, using this technique, are actually stronger than welds produced by fusion-welding.As the name implies, it stirs (forges) the molecules together. It makes the joint look like the rest of the metal (under microscope). Which means the "weld" has the same strength and mechanical-properties/characteristics as the rest of the metal.WHICH MEANS...... u have uniform load/stress dissipation throughout the metal.

but if it forges witout rebinding the metal into fustion would the weld be unsafe over the long period of time and the normal welding say mma when fused togeather with the filler rod would be better over time and more robust ????

where is the spinning bar, inside the pipe?

I am check u need grinder yes/no?

@T2DMF9000 no . it spinning bar that melts metal not sound

That's fuckin awesome!

I think i need one of these. Those guys gotta learn how to grind though.

Have you guys seen "You Can't Weld This!"? It's pretty funny... The guys over at WeldingMart com had it made! Do a youtube search for it :)

that leaves a pretty weld

movement and pressure = frictionfriction = heatIt doesnt MELT the metal, it FORGES (forces) the molecules together when the metal is in its sub-melt, "plastic", temp range. Its simple (in theory) and genius at the same time.
