PURPOSE:To execute an automatic arc welding without requiring a skilled technique and exclusive jigs and tools by constituting so that a torch traverser for an automatic welding machine can be moved by a movement of the first and the second arms and a rotation around a hinge and an electro-magnetic brake. CONSTITUTION:A continuous automatic arc welding of a three-dimensional linear part having an optional inclination against the horizontal surface is executed as mentioned below. That is to say, a rotation with regard to the Y axis and an inclination with regard to the X axis of a torch traverser body 16 for an automatic welding machine are executed by the respective rotations of the first arm 4 and the second arm 8 and a movement of the arm 8. Subsequently, after positioning of the body 16 is completed, its position is fixed by operating simultaneously electromagnetic brakes 2, 6, 9 and 13 connected to each joint 3, 7 by operating a push-button by a worker. Thereafter, an indicator 21 is shunted to the upper part, a torch 20 for the automatic welding machine is made to run from a start point of a surface to be welded to its end point, and the automatic arc welding is executed continuously. |
