At the AeroDef conference in Long Beach, Calif., Lincoln Electric's Mark Douglass talks about acquiring Baker Industries, experimenting in additive manufacturing—and planning to specialize in large-format metal AM: parts that are larger than a microwave. AM is a significant "growth leg" in the 124-year-old firm's just-hatched 2025 plan, he noted. Among the concrete examples in AM his firm can point to already: Oakridge National Labs now has three of Lincoln's robotic AM systems for producing large metal parts. Lincoln is set to this year open a 3D printing facility in Cleveland.
