Sensing
Find the Real Joint
3D vision and laser seam sensing locate joints, gaps and distortion before and during the weld.
THE PROBLEM
A Taught Path Misses a Moved Joint
Tack welds pull plates. Parts sit slightly off in the fixture. A robot that trusts nominal geometry places the bead where the joint should be, not where it is, and the defect shows up at inspection or later.
APPROACH
How Catfish Approaches It
Measure first, correct inside limits and keep what was measured.
3D Vision
Scan the part and locate it against the model.
Laser Seam Sensing
Find the joint line and gap before the arc starts.
Seam Tracking
Correct the torch path during welding within approved limits.
Post-Weld Inspection Scan
Capture the weld profile for the record: geometric scan data for review, with weld acceptance remaining with the customer's quality system.
HOW IT WORKS
Scan, Compare, Adjust
Measurements align the nominal path to the real joint, and every correction is logged.
- ScanCapture the as-built part.
- Compare to CADFind offset, gap and mismatch.
- Adjust PathShift the path inside WPS limits.
- RecordStore what was measured and changed.
