Large-Scale Metal Systems : Lincoln Electric

Lincoln Electric expanded into large-format metal additive manufacturing with its Wire-Arc Additive Manufacturing (WAAM) systems, designed and produced by Lincoln Electric Additive Solutions. The setup features company-built power sources, wire feedstock and Sculpt Print OS path-planning software, with the robot arm sourced externally, enabling prints roughly the size of an eight-foot cube and larger when segmented and joined.

Their vertically integrated pipeline ties Baker Industries’ machining and post-processing in Macomb, Michigan, to Lincoln’s Cleveland AM hub, with 26 robotic WAAM cells running 24/7. The systems handle heavy parts up to 20,000 lbs and print alloys including mild steel, high-strength low-alloy steel, multiple stainless and nickel alloys, iron-nickel 36 and copper-nickel 70/30.

For industries stalled by long casting and forging lead times, Lincoln’s WAAM approach shortens supply chains and enables on-demand production of large structural components. Certified to ISO 9001 and AS9100 and holding defense approvals, the offering targets repairs and replacements at casting scale where speed and material control matter most.
