MANU AI

AI weld quality inspection

Catch weld defects
during welding, not after

AI‑SMART WELD checks the weld every second and corrects it on the spot.
After welding, MANU RT helps inspectors read the X‑ray film.

Prevent defects while welding.
Confirm them in X‑ray.

Welding is automated, but defects are still found only afterwards.
Each one means another X‑ray, reading, re-weld and re-inspection.
We catch problems while welding and link that record to the X‑ray.

AI‑SMART WELD

In productionDuring welding
  • Judges weld quality about every second
  • Corrects the wire feed through the PLC
  • Checks the corrected weld (closed loop)

MANU RT

PrototypeAfter welding
  • Marks candidate defects on the X‑ray film
  • Inspector confirms 18 defect types and signs
  • Generates the X‑ray reading report

One record per seam
Welding anomalies and X‑ray defects are linked by position (mm).

Torch camera view with live AI verdict: segment 389, GOOD, confidence 0.986, PLC feed 1160

Retrofit

Uses the camera and PLC already on the line.
Existing interlocks stay unchanged.

Closed loop

Corrects the wire feed every 0.5–1.0 s,
then checks the corrected weld again.

Traceable

Every segment is recorded with video,
then linked to X‑ray results by position.

7 of 12 X‑ray defects start
with welding conditions

Heat input, wire feed and travel speed cause most of what radiography finds.
AI‑SMART WELD aims to cut those defects while the weld is being made.
