Altair Engineering Inspection deploys the full range of conventional non-destructive testing methods — executed by certified, field-experienced technicians, to documented procedures, against applicable inspection codes — delivering reliable inspection results across every industry we serve.
Conventional NDT methods remain the most widely specified, most broadly recognised, and most cost-effective tools for the routine inspection of industrial assets — and for good reason. Ultrasonic testing, radiographic testing, magnetic particle inspection, liquid penetrant testing, visual testing, and eddy current testing have decades of field validation, clearly defined acceptance criteria in established industry codes, and a depth of practitioner knowledge that newer techniques are still building.
At Altair Engineering Inspection, conventional NDT is not a secondary offering — it is the backbone of our inspection practice. Our conventional NDT teams are deployed daily across Oil & Gas, Petrochemical, Power Generation, Shipbuilding, Manufacturing, and Civil infrastructure environments throughout Asia and the Middle East. Every deployment is backed by documented procedures, calibrated equipment, traceable calibration records, and certified personnel — so that the conventional inspection results we deliver are as defensible as any advanced NDT finding.
What distinguishes our conventional NDT service is not simply what we deploy — it is how we deploy it. The right technique for the asset. The right procedure for the applicable code. The right certified technician for the method. And a report that gives you the information you need to make informed decisions about your assets.
The principal method for volumetric inspection and wall thickness measurement. Deployed for flaw detection, thickness gauging, corrosion mapping, and weld assessment across a wide range of material types and component geometries.
Learn More →Film, computed (CR), and digital radiographic (DR) techniques for volumetric imaging of welds, castings, and assemblies. Reveals internal discontinuities with permanent, reviewable image records referenced to applicable radiographic codes.
Learn More →A reliable surface-breaking discontinuity detection method for non-porous metallic and non-metallic components. Fluorescent and visible dye methods — deployed to ASME, EN ISO, and ASTM inspection standards.
