Unbelievable! Welding wood to wood, whoda thunk it?

Thanks for posting that CS.

Leave it to engineers to come up with a several million dollar machine to take the place of a $5.00 bottle of Elmer's Carpenter's glue !

Seriously though, a properly fitted glue joint is stronger than the wood on each side of the boundary layers. I wonder how strong that welded joint is ?

Similar process of binding wood when making of wood pellets in a pellet mill...pressure creates heat which cause the Lignin to bind all the particles as the mill extrudes the pellet form.

They made those because I'm selling the wood arc welders. I'm also marketing woodburning air conditioners.

Cellulose's melting point is pretty high ... I would think in the presence of oxygen it would just decompose at its melting point.

Rub 2 sticks together to make fire, not weld them together.
