These torches must be low profile, have high current capacity, and have special nozzles to permit access against the deck. Profile cutting of erection beams will require motion control and precision cutting parameters. Cutting technology needs to be developed for a variety of shapes especially thick bulb flats that have flanges over 3-inches thick. These make coping of the corner difficult. Welding procedures need to be developed which produce sound welds the first time eliminating over-welding and repair.
Robust arc welding procedures require weld joint preps that are smooth and uniform.
This project would evaluate the development of both semi-automatic and mechanized cutting tools. The tools must be lightweight, portable, and robust to shipyard conditions. Modular tooling concepts will be developed so a range of erection beam sizes can be accommodated with the cutting tools. A number of erection beam applications would be developed to support shipyard needs. Application development includes tooling, cutting parameters, and welding parameters.
