Companies
- MX3D · Amsterdam, Netherlands · founded 2014
Multi-axis robotic metal printing. The stainless steel canal bridge in Amsterdam was the proof. Wire-arc additive manufacturing for structure.
- ABB · Zurich, Switzerland · founded 1988
Industrial arms that have quietly become construction printers, prefab welders, and bricklayers. The muscle behind a lot of other logos.
- Inrotech · Odense, Denmark · founded 2000
Adaptive welding robots for heavy steel - ships, modules, and the prefab that construction borrows from yards.
- Shimizu · Tokyo, Japan · founded 1804
Smart Site: a Japanese general contractor that builds its own robots - ceiling install, welding, material transport - and runs them on its own jobs.
- Stud Automation · Pune, India · founded 2020
Robotic welding cells for construction steelwork. Indian fabrication yards automating the cage and the frame.
- Novarc · Vancouver, Canada · founded 2013
Spool Welding Robot. Pipe shops and modules - the weld that still sets the fab schedule.
- Path Robotics · Columbus, United States · founded 2014
Autonomous welding cells that see the joint and weld it. No teach-every-pass. Ohio steel.
- Lincoln Electric · Cleveland, United States · founded 1895
The weld OEM that now ships robotic cells into fab shops feeding construction steel.
- JLG · McConnellsburg, United States · founded 1969
Boom lifts - and now Canvas. The access OEM that bought the drywall robot.
- Progress Group · Brixen, Italy · founded 1961
Precast automation - carousel plants, mesh welders, the Italian line that pours the panel.
- Persona AI · Houston, United States · founded 2024
Industrial humanoids for shipyards, fab shops, and construction. NASA and IHMC DNA. HD Hyundai is the first yard. The weld is the job - not a laundry demo.
- Schindler · Ebikon, Switzerland · founded 1874
R.I.S.E. - an ABB arm in the hoistway that hangs rails so the elevator crew is not on a false car for weeks. Swiss lift OEM, shaft work.
- Fujita · Tokyo, Japan · founded 1910
Shibuya GC. SWAN welds square-tube columns on the deck with Daihen arms - Daiwa House on the joint development. The pass a welder used to sit in the heat to run.
- GMT Robotics · Brondby, Denmark · founded 2018
Mega WeldMate and WeldMate weld rebar mesh and cages adaptively. Brondby. Tunnel-segment welding demos - fab-first but construction steel.
- MESH · Zurich, Switzerland · founded 2022
ETH Zurich spin-off for robotic rebar - ACTUATE machine tending, NODE tying/welding cells, ASSEMBLE cage lines. Birr production hall. The ironworker pile that used to wait on a shop floor.
- MLROBOT · Hangzhou, China · founded 2019
ML1 is an all-terrain magnetic crawler welding robot (Meng Robot / MLROBOT) for tanks, steel structures, ships, and containers - China. Trackless mobility with laser seam tracking for multipass field welds.
- Sanctuary AI · Vancouver, Canada · founded 2018
Phoenix-class humanoids for industrial tasks including welding demos - Vancouver. Carbon-copy work that still needs dexterous hands on the torch or the plug.
