They’re using a linear friction welding machine which oscillates the sample at about 200hz. Their best guess is linen lignin cells within the wood are melting, interlocking and rejoining ...

Friction welding takes several forms, but it never melts the parent material of either part being joined. Linear, friction-stir, and rotational welding all have the same basic principle ...

Linear friction welding welds materials together using heat from friction. After placing two materials into a welding machine they are then pushed tightly together. One of the two materials moves ...

Here are a few more videos of friction welding: And linear friction welding is basically bananas: interesting Machinery Metal Recycling more of the copper, aluminum, and other minerals in our old ...

For people who have little awareness of new types of friction welding capabilities can you explain what Linear Friction Welding is? And why AFW is exploring the idea of adding this capability to the ...
