    I wonder how strong the joints are relative to a typical wood glue joint. This is basically just heating the wood enough to cause the lignin to act as an adhesive, similar to what holds firewood pellets together, right?

    The first guy to do it was horsing around and surprised at the results. Now he has to keep working on it so he doesn't get fired for his goofing around?

    Why? Why to increase the knowledge base. If I had such a machine I can guarantee you I would be curious about what it could do, about the limits of the process.

    People who ask why and who pursue the answers are the way we advance.

    I don't know specifically about that machine, but friction welding is used to join all sort of otherwise difficult to weld materials and to weld very dissimilar metals and high temp refractory metals. I'm very far from an expert, but did some reading about this a while back. I believe one of the benefits is a very small heat affected zone that is closely confined to the area where the weld takes place.


    There is actually quite a bit of info out there on the web about this, it is fascinating stuff.

    As to why weld wood, who knows. Though the link does make some reference to potential applications in building furniture (no need to wait for glue to dry, etc) and similar applications. Making super strong laminated wood beams, perhaps? I guess it's limited by ones imagination.
