Design, Construction, Demonstration and Delivery of an Automated Narrow Gap Welding System.
Abstract
The 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 carriers. The unique feature of the automated Narrow Gap welding process, is the narrow (1/4 - 3/8 - inch), square butt joint design. This narrow joint greatly reduces the volume of weld metal required for thick (2-4 inch) plates compared to the conventional, beveled joint design in current practice and represents the potential of providing reduced time and cost fabrication procedures. The weld metal is deposited with a modified, gas, metal-arc welding (GMAW process) resulting in very high joint finishing rates, excellent weld mechanical properties, and less distortion from welding. The program will be conducted in five phases: (1) Definition of Requirements; (2) Design of Welder Package; (3) Equipment Construction; (4) Qualification of Process and Equipment; (5) Shipyard Demonstration.
