    摘要: A friction stir welding tool having a drivable pin, which is rotatable around an axis, a shoulder element, a first shoulder and at least one spring. The pin includes a cylindrical engagement section that has a circumferential surface that engages a workpiece. The shoulder element includes a contact surface extending transversely to the axis for engagement with the workpiece. The shoulder element includes a friction block connected in a non-rotatable manner to the pin, on which a first friction surface is formed extending around the axis. The first shoulder part includes a second friction surface connected thereto in a non-rotatable manner, extending around the axis. The first and second friction surfaces face one another. The at least one spring biases the first friction surface against the second friction surface. The contact surface is formed on the first shoulder part.
