The invention relates to a device and a method for an axially aligned connection of long parts, in particular rails, by friction welding. According to the invention, it is provided that the friction welding device (A) has clamping elements (2, 2') for the part ends (11, 11') that can be set against one another and that at least one clamping element can be moved in an axially deviating manner relative to the opposite one, parallel to the cross-sectional plane (12, 12') of the part and positioned in a free-moving manner for the axial alignment of the part. The method according to the invention is characterized in that the cross-sectional surfaces (12, 12') of the part ends (11, 11') to be connected are pressed against one another in a heating step and that at least one part end is moved in an axially deviating manner relative to the opposite end and the front regions are brought to an increased temperature in this way, after which an axial alignment of the parts (1, 1') takes place in the free-moving position of said parts and the welded area is placed under increased pressure for the holohedral metallic bond of the ends (11, 11') of the parts.
