zSCAN

3D Profile Scanner

This is a laser based high precision 3D profile scanner which can scan 1000 profiles per second and output the data in real time.

The system comes with an auto-tune feature to adapt to shiny and glossy surfaces which otherwise are very difficult to scan.

It can be used to measure vibration, height inspection and surface profiling in real-time — and pairs with the Inspectis vision-AI camera to deliver complete, automated weld inspection: surface defects and true 3D geometry in a single pass.

3D PROFILOMETER

Integrated Weld Inspection

See the weld. Then measure it.

A single platform that fuses AI machine vision with 3D laser profilometry. The Inspectis camera reads the surface condition of the weld — spatter, porosity, cracks, undercut — while zSCAN captures the true geometry of the bead. Gridbots fuses both data streams to detect, measure and grade every weld automatically, in one pass.

Vision AI

Inspectis

High-resolution machine-vision camera with on-device AI that inspects the weld surface and classifies defects in real time.

Detects: surface cracks, porosity, spatter, undercut, overlap, discolouration and missing / short welds
Delivers: automatic defect classification, pass/fail flags and annotated images for every joint

3D Laser

zSCAN

High-precision laser line profilometer that scans 1000 profiles per second to reconstruct the weld cross-section in 3D.

Measures: cap height & width, toe angle, undercut depth, hi-lo mismatch, leg length and throat
Delivers: real-time point cloud, dimensional readouts and profile grading against your acceptance limits

What It Measures

From a single laser sweep, zSCAN reconstructs the weld cross-section and derives every geometric parameter your code cares about. Each value is compared against your acceptance limits and graded automatically.

Annotated butt-weld cross-section reconstructed from the laser profile.

Parameter	Typical Limit
1 Cap Height (reinforcement)	≤ 3.0 mm
2 Cap Width	Per WPS
3 Toe Angle	≥ 150°
4 Undercut Depth	≤ 0.5 mm
5 Hi-Lo Mismatch	≤ 1.5 mm
6 Leg Length / Throat	Per WPS

Limits are configurable per weld procedure and acceptance standard.

DEFECT SEVERITY INDEX

Every joint is auto-scored and placed on an Accept / Monitor / Reject scale, so operators act on the worst welds first.

COVERAGE vs MANUAL NDT

Automated scanning inspects 100% of the weld length versus the sampled spot-checks typical of manual inspection.

Applications

Pipelines

Girth and seam welds on transmission and process pipelines, inspected in the field on tracked crawlers.

Pressure Vessels

Longitudinal and circumferential welds on tanks, boilers and vessels held to code-critical tolerances.

Shipbuilding

Hull plate and block welds where long, continuous seams demand full-length, repeatable inspection.

Wind & Structural

Tower cans, nodes and heavy structural joints where geometry and fatigue-critical toes matter.

Why Fuse Vision & Laser

Complete picture — surface condition and true 3D geometry from one pass, not two separate inspections.
Objective & repeatable — removes operator-to-operator variation with quantified, logged measurements.
100% coverage — inspects the full weld length instead of manual spot samples.
Faster throughput — real-time data at 1000 profiles/sec keeps pace with production.
Automation-ready — trigger inputs and GPIO integrate directly with robots and crawlers.
