Precision 3D laser scanning metrology provides submillimetre dimensional accuracy across components and assemblies that exceed the capability of manual measurement tools or conventional contact-based CMM inspection. Altair Engineering Inspection provides high-precision 3D scanning for dimensional verification, corrosion assessment, pipe ovality, pipe end profile inspection, and reverse engineering — delivering complete three-dimensional form capture against CAD nominal geometry or engineering tolerances, on components from small precision fittings to large fabricated structures
Precision Scanning Applications
Corrosion Assessment — Full Surface Coverage
3D laser scanning captures millions of data points across the entire
accessible surface — producing a complete topographic map of material loss.
Pitting depth, general wall thinning, and corrosion extent are measured and
visualised across the full component profile — not at discrete grid points.
Scan data is registered against nominal geometry for FFS assessment input.
High-Precision Metrology
Full-form capture against engineering tolerances and GD&T
specifications — on turbine casings, pressure vessel heads, nozzle connections,
flanged assemblies, and precision structural elements. Non-contact scanning
eliminates deformation risk on precision-machined surfaces. All metrology
scanning is traceable to UKAS-accredited calibration standards.
Pipe Ovality Assessment
Full circumferential profile capture at every nominated section —
identifying local deformations, asymmetric ovality, and buckle initiation
geometry that discrete calliper readings miss. Results reported against ASME
B31.3, B31.4, B31.8, DNV-ST-F101, or operator-specific specifications.
Pipe End Profile Inspection
Bevel angle, land width, root face geometry, and end squareness captured
across the full pipe end circumference — not at four or eight manual
measurement points. Continuous bevel angle variation, root face width, and
squareness data enables go/no-go disposition before joint assembly, identifying
out-of-tolerance zones that require dressing before welding proceeds.
Outputs include registered 3D point cloud data, false-colour deviation
maps, GD&T deviation reports, CAD overlay visualisations, section cut
dimensional analyses, circumferential ovality and bevel profiles, and
measurement uncertainty statements. All outputs are structured for engineering
review, regulatory submission, and quality management system documentation.
