Claims

[Claims for Utility Model Registration] In a downward automatic welding device for the branch pipe portion temporarily welded to the body of a cylindrical structure having a plurality of branch buildings, the center of the body and the center of rotation of the welding support frame substantially coincide with each other. A torch stand is rotatably attached to the center of the branch pipe that forms a plane parallel to the mount surface located at an arbitrary eccentric position in the body, and the torch stand is equipped with an arm length extension and contraction mechanism. The torch stand is provided with a means for always maintaining a vertical position around the center of the branch pipe with respect to the plane of rotation of the pedestal, and the torch stand is provided with means for always maintaining a vertical position around the center of the branch pipe, and the angular velocity of the rotation of the pedestal and the weld line of the branch pipe are controlled. A downward welding device characterized by having a means for rotating the torch head at a constant relative angular velocity.
