Physical AI — welding & metal fabrication

The fab shop,under autonomouscontrol.

The premise

Weldeon is the operations layer for welding and metal fabrication. It cuts, fits, welds, sequences, inspects and paces — closing the loop from perception to robot and parameter control, and hitting the target weld quality, distortion and takt before the arc strikes.

The problem

Welded joints carry the built world. We still make them by hand.

Bridges, ships, pressure vessels, pipelines, wind towers, rail cars and heavy equipment all rest on the same thing: a joint that must carry stress and pressure for decades without a crack or a pocket of unfused metal. Every one of those joints is a small, unforgiving act of manufacturing.

Fabrication means cutting and forming to exact geometry, fitting up and tacking to a precise gap, welding with exact heat input and travel speed, managing the distortion that heat inevitably creates, and inspecting for the flaws you cannot see. A bad fit-up, a heat-input error, an arc instability or a hidden lack of fusion turns into rework, rejection, or — at worst — a field escape.

And the shop floor is running out of the people who can do it. The welder and fitter shortage is severe and worsening, the work is hazardous and ergonomically punishing, and managers run blind on real-time weld quality, heat input, distortion, yield and weld genealogy across the whole line.

The loop

Three moves, made continuously

Weldeon senses the joint, decides the pass, and moves the robot — then checks its own work against the code before the part moves downstream.

Weld and parameter control

The weld agent holds heat input, travel speed, wire feed and weave inside the qualified WPS envelope while tracking the seam in real time. When the joint moves — and it always moves — the parameters move with it.

  • Arc, laser and resistance processes
  • Through-arc and laser seam tracking
  • Bounded parameter authority inside the qualified WPS

Machine-read inspection

The defect agent reads radiography, phased-array ultrasonic and shop vision to find porosity, cracks, lack of fusion, undercut and slag — and, more usefully, to predict them from the arc signature before the weld is finished.

  • Digital RT, PAUT and vision
  • Indication called with a confidence figure
  • Every call reviewable by your qualified inspector

The as-welded digital twin

Before the arc strikes, the twin simulates the weld sequence and predicts distortion, residual stress and takt. Sequences are chosen on the model, not on the assembly — so the expensive lesson happens in software.

  • Distortion and residual-stress prediction
  • Sequence and heat-balance planning
  • Takt impact modelled per station
“A weld is a decision made a thousand times a shift. Autonomy is simply making it the same way every time.”

The agents

Eight agents, one closed loop

Each agent owns a scope of the shop. They share one model of the part, one weld record, and one definition of done.

  1. 01

    Cut & form

    Controls plasma, laser and oxy cutting, nesting, bending and forming so plate and sections leave the front of the shop at the geometry the joint actually needs.

  2. 02

    Fit-up & tack

    Senses and controls root gap, alignment, bevel and tack placement — the single largest upstream cause of weld failure and rework.

  3. 03

    Weld & parameter

    Runs robotic arc, laser and resistance welding: heat input, travel speed, wire feed, weave and real-time seam tracking, pass by pass.

  4. 04

    Distortion & stress

    Plans weld sequence, balances heat, and predicts out-of-plane distortion and residual stress before the assembly leaves tolerance.

  5. 05

    Defect & inspect

    Reads X-ray, ultrasonic and vision data to detect and predict porosity, cracks, lack of fusion, undercut and slag — machine-read, engineer-approved.

  6. 06

    Yield & takt

    Optimises first-pass yield, rework hours and line balance across cutting, fitting, welding and finishing stations.

  7. 07

    Robot & handling

    Drives welding robots, positioners, gantries and part handling — including approach, reach and collision-free motion around large weldments.

  8. 08

    Quality & conformance

    Holds right-first-time, non-conformance, weld genealogy and code traceability to AWS D1.1, ASME BPVC, ISO 3834 and EN 1090.

How it runs

A shift on Weldeon

The loop is the product. Everything else — dashboards, reports, genealogy — falls out of it.

  1. 01

    Plan on the twin

    The part, the joints and the weld sequence are simulated overnight. Distortion, stress and takt are predicted; the sequence with the best margin wins.

  2. 02

    Cut, form, fit

    Nesting and cutting run to the geometry the joint needs. Fit-up is measured, not assumed: gap, alignment and bevel are held before a tack is placed.

  3. 03

    Weld under control

    The robot runs the pass. Seam tracking, heat input and travel speed are adjusted continuously inside the qualified envelope, pass by pass.

  4. 04

    Inspect in line

    Arc signature, vision, RT and UT are read as the weld is made and immediately after. Indications are called with confidence and routed to your inspector.

  5. 05

    Record and learn

    Every weld leaves a genealogy record — WPS, consumable lot, fit-up, heat input, passes, NDT, distortion. The fleet gets better at the joints you actually build.

Rate

One station over takt sets the rate of the whole shop

The yield-and-takt agent balances cutting, forming, fit-up, tacking, welding, distortion management, NDT and finishing against the line's takt — and shows you the station that is actually costing you rate.
