A device for welding together a first elongate work piece (1), such as a first rail, with the second elongate work piece (2), such as the second rail, and face to end face, by means of butt-weld resistance welding, particularly flash welding, comprising a frame structure (3) and a carriage (4) movably connected to said frame structure and slidable with respect thereto in the longitudinal direction of the work piece. The device further comprises a first clamping device (5a, 5b) mounted on said frame structure or parts associated therewith to fixedly clamp the first work piece (1), a second clamping device (9a, 9b) mounted on said carriage to fixedly clamp said second work piece (2), electrodes (7, 11) mounted on said frame structure etc. and the carriage or on the clamping devices to heat the work pieces to the desired welding temperature, and a press element (13, 14, 15) to press the facing ends of the heated work pieces against one another in the longitudinal direction of the work pieces to form a bonding welding joint. The device likewise comprises at least two actuators (13, 14, 15) which are individually controllable relatively to one another for turning the facing ends of the work pieces (1, 2) in such a manner that the transverse axes (t1, t2) and/or the vertical axes (h1, h2) and/or the longitudinal axes (l1, l2) of the work pieces form an angle .alpha., .beta., and .delta., respectively between one another, or in such a manner that an existing angle .alpha., .beta., and .delta., respectively, formed between the transverse axes (t1, t2), and/or the vertical axes (h1, h2) and/or the longitudinal axes (l1, l2) respectively, of said work pieces is essentially eliminated prior to and/or during and/or after the pressing operation.
