摘要: An automatic welding apparatus includes a movable welding torch carried by a positioning assembly mounted on a pair of turn frames adapted to be rotated about a horizontal axis. The positioning assembly is capable of orienting the welding torch with respect to a workpiece holder also mounted on the pair of turn frames. A computer control arrangement accurately positions the torch along three mutually orthogonal axes during welding, and controls the angular position of the pair of turn frames about the horizontal axis. In alternative embodiments, the workpiece holder is mounted on a pair of stationary stands so that the holder is independently rotatable around a horizontal axis which may be coincident with, or offset from, the axis of rotation of the turn frames. The arrangement permits automatic torch positioning for downward butt welding or horizontal fillet welding on the interior or exterior of long box-like or tubular members.
