Abstract:

The overall objective of this program is to design, construct, demonstrate, and deliver an automated, Narrow Gap welding system capable of welding high strength steel plates under shipyard production conditions in the construction of aircraft carrier decks. The unique feature of the automated Narrow Gap welding process, is the narrow 38-inch, square-butt joint design. This narrow joint greatly reduces the volume of weld metal required for thick 2-to 4-inch plates compared to the conventional, beveled joint design in current practice and represents the potential of greatly reducing fabrication time and costs. The weld metal is deposited with a modified, gas-metal-arc GMA welding process resulting in very high joint finishing rates, excellent weld mechanical properties, and less distortion from welding.
