(4) is moved so that the arc point is automatically changed to correspond to the change in the angle of the longines.

In addition, when there is an angle change in the music block in which the driving wheels 74 and 74` come into contact, the corner guide is installed on the vertical seam tracker 4 by the torch grip holder 48 and rotates and moves along the music block. The roller 45 'of the bar 4' detects this and changes the welding work angle by the spring elastic force of the vertical shim tracker 9 connected thereto, and at the same time, changes the vertical arc point. That is, the corner guide bar 4 'is installed on the vertical seam tracker 4 by the torch grip holder 48 like the torch, and the vertical seam tracker 4 is rotated on the vertical slide unit 9. Since it is installed to be possible, the torch grip holder 48 and the vertical seam are formed by the roller 45` of the corner guide bar 4` which is moved along the curvature of the song block when there is an angle change in the song block. The tracker 4 rotates around the insertion pin 41 by the angle change of the music block to change the welding work angle, and corrects the vertical arc point by the internal spring elastic force of the vertical shim tracker 9, and is connected to one side. By changing the horizontal position of the horizontal guide bar 3 ', the horizontal arc point correction is generated by the spring elastic force inside the horizontal seam tracker 3.

As described above, the present invention changes the torch working angle by the corner guide bar and the work angle correction shim tracker, and changes the welding point by the horizontal guide roller and the welding arc point correction shim tracker. The electromagnet installed in the curved outer plate can be used for automatic fillet welding of longitudinal and transverse slopes by the automatic driving device that adds stability to the running of the transverse plate. There is an effect to be improved.

In addition, since one worker can use multiple automatic welding devices, the work efficiency is improved, the work environment is improved, and the worker's fatigue is reduced.
