A mobile device for making welding grooves comprises a milling head (3) which is provided with a hydraulic motor and a milling cutter (4) driven by the hydraulic motor and is accommodated in the centre area of a roughly C-shaped support (2). Supporting rollers (6), projecting on the plate side beyond a stop (15) defining the cutting width, or driven feed rollers (7), which are located opposite these supporting rollers (6) at an adjustable distance and can be adjusted in the feed direction, are supported on the bottom or top leg of the C-shaped support (2). <IMAGE>
