Abstract: An adaptive and synergic fill welding method and apparatus enables automatic, or adaptive fill, and user directed, or synergic fill, modes to provide improved fusion quality, by ensuring that base metal dilution of a weld remains within a predetermined range. The apparatus includes a means for profiling and tracking a joint, and multi-part adjustable welding means. In adaptive fill mode the method automatically varies a plurality of welding parameters in response to measured variations such as joint width between work pieces. In synergic fill mode, the method enables a user to vary multiple welding parameters in response to joint variations by adjusting a single variable, a synergic fill number, which may be controlled by means of a user interface pendent. The multiple welding parameters may include predetermined wire feed speed, torch travel speed, welding voltage and current, torch oscillation width, dwell time, and a plurality of bead size parameters.

Abstract: A torch cutting tool has a clamp that is attached to a workpiece with the clamp having a rotating platform with an attached first latch member. A second latch member is attached to a track with a moveable carriage on which is mounted a positioning arm with a torch holder. After the clamp is attached to the workpiece, the second latch member is quickly latched to the first latch member to effect quick and simple setup. A cam follower, a second rotating platform, a second positioning arm, a covered track, a rotating base plate and metered fuel and oxygen supplies make the tool simple and easy to use.
