Basic process of friction stir welding Tool in China FSW Supplier

Friction stir welding (FSW) is a solid-state joining technology.

During the welding process, a cylindrical FSW tool with a special shoulder and needle protrusion rotates and inserts into the welded part. The frictional heat between tool and work-piece causes softening in the materials around the pin without melting.

When the FSW tool moves forward along the interface to be welded, the thermoplastic material is transferred from the front to the back of the FSW tool, and under the mechanical forging of the tool, solid-state joining between the work-pieces is achieved.

The process parameters of FSW mainly include tool rotation speed, welding travel speed, inclination angle, pressing amount, and cooling environment. 

Different combinations of welding parameters can affect the thermal cycling, tool loading state, and material rheological behavior during the welding process.

Various parameters are not independent of each other, and through optimized parameter combinations, high-quality welds without defects can be obtained.
