The torch adjustment plate, which holds the torch by clamping the table and the torch adjusting unit by driving the up and down driving ballscrew, detects the angle and distance of the torch by the angle adjusting roller and the distance adjusting slider between the angle moving guide and the distance moving guide. By means of automatic adjustment by means of automatic adjustment, and by installing the optical fiber sensor on the guide bar extending from the torch correction table at both ends of the guide roller, the guide roller line and the torch correction table driving ball screw line are formed at 0-5 ° angle with the main body.

There is no change in the case of the height change of the spring in the shock absorber according to the height change of the surface, but if it is more than that, the torch part is lifted to maintain the welding distance, but the welding torch is used for three-dimensional curved welding. Will not be able to cope effectively.

To this end, the present invention amplifies the signal from the strain gauge of two pairs of X and Y plates, which has been proposed in the applicant's source technology 2003, Republic of Korea Patent Application No. 333232 'Welding line tracking device using strain gauges' The PWM waveform produced by comparing this signal with a triangular wave forms a DC motor with a power MOSFET so that it can be reversed and reversed, and the welding torch is simultaneously changed to the XY axis according to the + and-outputs of the strain gauges that quench the curved welds. The present invention is to provide an automatic carriage welding machine for ship surface welding, which allows welding work to be carried out even horizontally or vertically by magnetic clamping.
