Friction friction welding technology for joining components made of different materials

摘要

Machining device comprising a component receptacle (61), a manipulator (62) and an FSW tool (10) guided by the manipulator (62), wherein the component receptacle (61) is designed to hold the first component (20) and the second component ( 30) and characterized in that the processing device (61) comprises a controller (64) adapted to carry out a friction stir welding process for connecting two components (20, 30), wherein the first component (20) consists of a Material having a first low melting temperature, in particular of aluminum, and the second component (30) of a material having a second and significantly higher melting temperature, in particular of steel, and wherein the friction stir welding method comprises the following steps: - Positioning of the first and second component (20, 30) to form a butt joint between a first abutment edge (21) of the first component (20) and a second Abutting edge (31) of the second component (30); - contacting the first component (20) by a FSW tool (10) in a surface area (22) adjacent to the butt joint; Locally plasticizing the material of the first component (20) and immersing (Z1) the welding pin (11) of the FSW tool (10) in the plasticized material (40); - substantially perpendicular pressing (Z2, FN) of the welding pin (11) of the FSW tool (10) to the second abutting edge (31) of the second component (30), in particular without plasticizing the material of the second component (30); - Guiding (Z3) of the FSW tool (10) in a welding direction (SR) along the second abutting edge (31) of the second component (30).
