Linear Friction Welding (LFW) is an advanced manufacturing technique that has gained significant attention in recent years, particularly for its applications in aerospace and automotive industries.

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 ...

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 ...
