To all the welders and people interested in metallurgy we have a very awesome video that shows and elaborates the linear friction welding process in great detail. Linear Friction welding or LFW for short, is very similar to spin welding. The difference between these two is that when friction welding the moving chuck goes sideways instead of spinning. The speeds with this technique are much lower which requires the piece to be under constant pressure. The components are required to have a pretty high shear strength as well. With linear friction welding you need to have complex machinery as well.
The Linear friction welding process is ideal for joining blades to disks in turbine manufacture. These are called blisks. They are mostly made for aircraft turbine engines. They have a great potential in other aerospace implementations as well. For example, in the manufacture of various aircraft structural components. As you can see, linear friction welding is capable of creating components which can be compared in both quality and strength to machined components. Other industries in which linear friction can be implemented are the shipbuilding, automotive, energy and construction etc. Take a look in the video below and tell us what you think about this type of welding.
