What is a pin tool in friction stir welding?

The FSW tool pin is one of the components of our friction stir welding tools. It is located at the end of the tool in the extension of the shoulder. The length of the FSW tool pin depends on the thickness of the parts to be welded and the welding configuration.
The threaded pin ensures efficient mixing by penetrating the material and mixing it. This shearing effect provides an additional amount of heat that contributes to the plastic deformation of the material. Its sharp point ensures a better penetration of the tool’s pin into the workpiece and thus a more efficient FSW welding operation.
Stirweld offers a complete range of FSW tools according to the materials of your parts. The French space giant Ariane already trusts us for the purchase of its FSW tools. Download our catalog which lists our standardized FSW tools.
