    Abstract: A friction stir welding tool, which includes a pin and a shoulder rigidly connected to the pin, for welding components composed of a parent material having a melting point of more than 900° C., in particular steel. To achieve a particularly long service life of the tool even with thick-walled components, it is provided that the shoulder is at least partially composed of a first material and the pin is at least partially composed of a second material. Furthermore, the shoulder is at least partially composed of a first: material and the pin is at least partially composed of a second material. In addition, a method for joining components of one or more parent materials having a melting temperature of more than 900° C. is provided.

    Abstract: The method for producing a metal member includes a step of preparing a first member made of a first metal and having a recessed portion formed therein, and a second member made of a second metal having a smaller deformation resistance than the first metal, and a step of joining the first member and the second member. The step of joining includes a step of increasing temperatures of the first member and the second member by relatively rotating the second member with respect to the first member while pressing the second member against the first member with at least a part of the second member being received in the recessed portion, and a step of stopping the relative rotation of the second member with respect to the first member and cooling the first member and the second member with the members being pressed against each other.
