Friction Stir Welding (FSW) Machine Process and Application – Friction Stir Welding Perhaps only a few people know about this friction welding. They are interested in the mechanic world. However, for you who are not familiar with Friction Stir Welding, the article would help to describe it. For knowing the term.

Here is the description was given. Friction welding is a welding process of solid-state where the combination can be obtained that caused by the hot friction and pressure. Usually, the friction typically occurs at two surfaces of the object which relatively rotating to one another for increasing the temperature of the surface.

Friction Welding usually does not use filler material. It also does not require any welding flux. Besides, Friction Welding also does not use a shielding gas, and there is not thawing the object. The present writing will help the readers to understand about Friction Stir Welding.

Based on the historical point of view. For the first time, In the Soviet Union was the place where the friction welding founded and the first research took place in 1956. Caterpillar company from America and then the Rockwell International. I Europe and in the Soviet Union, patents were also established. The American Welding Society is the largest organization that kept historical records.

Friction Stir Welding (FSW) Processing and Applications:

Friction Welding is usually used to weld various shaft and tubular components. Friction Welding can be found in the automotive, aircraft, agricultural equipment, oil, and gas.

The method of friction welding is free of melting, which reduces the growth of grain in engineered materials, for instance, steels heat treated with high strength. The benefit of friction welding is to clean the surface of the materials being welded; it means that they can be joined with less preparation.

At the time of the friction welding process, it depends on the methods being used the small pieces of the plastic or the metal will be forced out of the working mass. It is trusted that the flash brings away debris and dirt.

Let’s see another advantage of friction welding. Namely, dissimilar materials are allowed. This is very beneficial in aerospace; generally, the big distinction of melting points of the two materials will make it impossible to weld by using traditional methods and will require some mechanical connection.

Friction welding is also applied with thermoplastics, which can be seen in an analogous fashion to metals under heat and pressure. These materials use much lower heat and pressure than metals, but the method can be applied to join metals to plastics with the metal interface being machined. For example, the method can be applied to join eyeglass frames to the pins in their hinges. The varieties of the method are permitted to apply for lower energies and pressures.

That’s all about the friction stir welding. Hopefully, after reading this short description of friction welding, you can gain at least the definition of the term. If you want to be a welder just let yourself search for anything that relates to welding to complete your knowledge.
