Disclosed is a friction stir welding method of different materials. An embodiment of the present invention, in a friction stir welding method of different materials with different melting points, provides a friction stir welding method comprising: a step of forming a welding line by piling up a first metal member having a high melting point and magnetism, and a second metal member having no magnetism for a part of theirs to be overlapped; a step of performing high-frequency inductive heating for the second metal member making the formed welding line, and heating the first metal member contacting it at a certain temperature; and a step of inserting a friction stir welding pin into the second metal member making the formed welding line, and performing friction stir welding. The present invention provides a friction stir welding method of different materials which is able to obtain a stable and high bond strength. |
