TetraGen Autonomous Welding Robot

TetraGen Robotics is a Winnipeg, Manitoba company founded in 2022 that builds autonomous welding robots. It targets fabricators that struggle to program robots for varied parts, such as heavy equipment, agricultural equipment, trailers, mining equipment and structural steel.

The system pairs a conventional welding robot cell with proprietary AI software and 3D vision. It scans the part, generates its own robot program and adapts to part variation without manual programming. In August 2026 the company closed an oversubscribed CAD 1.8 million seed round led by StepChange Capital.

• AI weld planning: model optimizes weld paths and makes real-time decisions.
• 3D vision: proprietary scanning of part features.
• Program generation: robot programs created automatically.
• Variation handling: adjusts to real-world part variation.
• Welding cell: robotic cell with built-in vision system.
• Partner ecosystem: FANUC, Fronius and Vention logos shown on the site.

A steel-structure workshop welding varied brackets and frames without writing robot programs. A heavy-equipment or agricultural machinery maker welding low-volume parts. A trailer manufacturer reducing rework on repeat joints.

No manual robot programming for varied parts. Shorter setup and faster deployment. Consistent weld quality with less rework. Adjustment to part variation without operator intervention.

High-mix fabrication is hard to automate with teach-and-repeat robots, so AI-driven programming-free welding is attracting funding. Vietnamese heavy-fabrication and structural steel workshops with varied parts face the same programming barrier.

Based in Winnipeg, Manitoba, Canada; founded 2022 per BetaKit. Seed round of CAD 1.8 million announced August 2026, led by StepChange Capital with Emend Vision Fund. Customer named on site: Spence Manufacturing. Target market is North America.
