The automatic joining system includes: a fixing device; a friction stir device; a measuring unit; and a controlling device, in which a rotating tool includes a base end side pin and a tip end side pin formed continuously to the base end side pin, the controlling device sets a target moving route along which the rotating tool moves when friction stir joining of a butting portion is performed, based on a ridge line position before the friction stir joining is performed, and also sets a modified moving route at a position displaced toward a first metallic member side in substantially parallel with respect to the target moving route, and the friction stir device controls the rotating tool to move along the modified moving route and thereby performing the friction stir joining along the target moving route.
