Weld & Fabrication

This is the Weld & Sheet Metal Fabrication area. It has an array of capabilities including lasers for cutting metal plate, forming, conventional machining and robotic welding. All weld processes are certified as per AWS Weld standards.

The sheet metal area has the capability to laser cut and form armor plate, and shear, form and straighten metal. Two NC press brakes and a Whitney punch are available, and a limited amount of tube forming is performed. Turning, sawing, drilling, milling and layout operations are in the machining area. Fabricators assist the welders with fabricating weldments and setting up the modular fixtures for jobs.

Components of Weld and Fabrication are present in other areas as well. A focused factory is being set up specifically for the Forward Repair System (FRS) and the Shop Equipment Contact Maintenance (SECM). Water jets, band saws, and flame cutters are located in a different building on the island.

There are a variety of success stories from this area. For the FRS, welders reconstitute flat racks, rebuild them, and assemble components of the enclosure and floor. A stress fixture to form the OSV turrets was developed here. This process guarantees greater safety for the welders and expedites the process. A robotic welding sequence was designed to perform higher quality on the main post of the M6 pedestal and also the components for the M7 and the FRS.
