MACOMB, MI – Baker Industries, a Lincoln Electric Company, and Lincoln Electric Additive Solutions (LEAS) today announced a new strategic relationship with General Atomics Aeronautical Systems, Inc. (GA-ASI) on a research and development project exploring the feasibility of wire-arc additive manufacturing (WAAM) for producing steel layup tooling used in the manufacturing of composite lamination for GA-ASI’s unmanned aerial systems (UAS).
Our turnaround time can be significantly quicker than larger job shops, and we can usually ramp up production quickly to combat fluctuations in customer demand.
Mike Wangelin, Business Development Manager, Lincoln Electric Additive Solutions/Baker Industries
Coupled with Baker’s robust post-processing, fabrication, and inspection capabilities, WAAM’s ability to quickly produce large, complex components using several materials could present a comprehensive solution to GA-ASI’s production tooling needs.
While still in the process of qualification at GA-ASI, the process has demonstrated preliminary success toward reaching production-level use in GA-ASI’s manufacturing operations. Overall, GA-ASI has seen savings ranging between 30-40% in cost and about 20-30% in lead time using WAAM in place of traditional manufacturing processes for specific tool families and geometries. In addition, the first tool produced has passed GA-ASI’s initial assessments. It is vacuum-tight, has a uniform thermal survey, and exceeds target GD&T requirements.
