AUTOMATIC TIG WELDING MACHINE AND SMALL DIAMETER PIPE INSIDE AUTOMATIC TIG WELDING MACHINE

摘要

PURPOSE:To perform welding or cladding on a part having only limited space by moving a tungsten electrode in the tungsten electrode longitudinal direction by the movement of a torch in the tungsten electrode longitudinal direction and orthogonal direction and controlling an arc length. CONSTITUTION:The automatic TIG welding machine can move the torch 8 in the vertical directions of the torch via a fixed fulcrum 6 and a floating fulcrum 7 by the movement in the vertical direction and orthogonal direction of the torch having the tungsten electrode 8a. As a result, even if the space in the vertical direction of the torch is limited, the movement of the torch in the vertical directions can be controlled.
