It is cool but it isn't new technology.
Friction welding and friction stir welding have been round for quite a long time. Airbus were some of the early pioneers in it. It doesn't require a filler rod so they saved a ton of weight when building the wings for the A380. It also produces a far smaller heat affected zone (HAZ) as the metal doesn't actually melt. It just softens.
JCB use it to build their hydraulic rams. They use it to weld the end bits onto the pistons as the weld is across the whole of the two parts and not just round the edge.

Friction welds are some of the strongest available
they weld train wheels / axles this way
and some pipe lines
as said above - doesn't quite melt - so not much oxidisation
sadly not much use on the mini bodywork

New SLK is supposedly going to be welded like this.
Just read about it on PH the other day, had no idea what friction welding was,
