    • The present invention relates to a mobile seam welder and to a method for controlling the welding operation thereof. A mobile resistance seam welder of the present invention comprises an upper control unit (110) and a lower control unit (120) for synchronizing the movement speed of a mobile unit and the rotating speed of an upper disk electrode (101) and of a lower disk electrode (101'). The upper control unit (110) and the lower control unit (120) comprise: respective first measuring units (111, 121) for measuring the driving force (F1) produced by the friction force between the upper and lower disk electrodes (101, 101') and a welding target (m); respective second measuring units (113, 123) for measuring a force (F2) resistant to the rotation of the upper and lower disk electrodes (101, 101'); and first and second motor force determining units (114, 124) for determining the driving force (F3) of upper and lower servomotors (107, 107') such that a condition (F1>F2) in which the measured driving force (F1) is always bigger than the measured force (F2) is achieved in order to prevent slippage between the disk electrodes (101, 101') and the welding target (m). The first and second motor force determining units (114, 124) determine the driving force of the upper and lower servomotors (107, 107') such that the force (F2) resistant to the rotation of the upper and lower disk electrodes (101, 101') has a minimum value in accordance with the static friction force and kinetic friction force which are calculated by the torque values of the upper and lower servomotors (107, 107'). According to the present invention, the speed of the mobile unit and the speed of the disk electrodes are synchronized in spite of the variation in the outer diameters of the disk electrodes, to thereby maintain welding quality at a constant level and to thus improve welding performance.
