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 ...

Figure 1. Friction welded parts including valves and a gearbox fork. Linear friction welding, (so named because the relative motion is linear across the interface, rather than rotary), is already used ...

Now arriving in Middletown: The world’s largest welding machine. Early Wednesday morning, the linear friction welding machine is expected to roll into Pratt & Whitney’s Middletown assembly ...
