Robotic Ultrasonic Immersion Systems

When Component Geometry Demands More Than a Linear Scanner

Complex-geometry components such as turbine blades, aero-engine disks, forged rings, structural titanium parts and composite structures present inspection challenges that conventional Cartesian scanners cannot reliably address. Surface curvature, varying wall thickness and complex internal structures require an inspection system capable of adapting to the component rather than forcing the component to adapt to the scanner.

Altair Systems Robotic Ultrasonic Immersion Systems combine six-axis articulated robotic motion with immersion ultrasonic testing to deliver adaptive, high-precision volumetric inspection across complex component geometries. The robotic system maintains optimal probe-to-surface alignment throughout the scan path, ensuring consistent acoustic coupling and accurate defect detection across the entire inspection volume.

Each system is engineered around the geometry of your component, the inspection standards you must meet, and the production throughput required by your manufacturing environment.

System Capabilities

• Six-axis articulated robotic inspection platform with programmable scan trajectories
• Support for Conventional UT, PAUT, TFM/FMC, TOFD and Through-Transmission Ultrasonic methods
• Water immersion or water-column coupling configurations
• Sub-millimetre positional repeatability with encoder-synchronised data acquisition
• Multi-probe head configurations for parallel channel inspection
• Optional 7th and 8th axis integration including linear tracks and rotary positioners

Inspection Applications

• Aerospace engine components including turbine blades, disks and compressor parts
• Structural forgings and castings in titanium, nickel and aluminium alloys
• Composite structures such as CFRP panels and bonded assemblies
• Power generation components including rotor disks, shafts and pressure vessels
• Defence and nuclear components requiring traceable inspection documentation

Inspection Workflow

Every system is engineered through a structured inspection workflow beginning with application engineering and scan plan development. Component geometry is analysed, ultrasonic probes are selected and scan parameters are validated using simulation tools before system build.

Robotic scan trajectories are then generated using the component CAD model to ensure optimal probe orientation and complete inspection coverage. Calibration standards are used to establish sensitivity settings and acceptance thresholds before the automated scan is executed.

During inspection the system collects encoder-synchronised ultrasonic data and produces real-time A-scan, B-scan and C-scan visualisation. After the scan is complete, inspection data is analysed and a complete inspection report is generated including calibration records, scan coverage maps and defect indication logs.

Key System Features

Why Altair Systems

The performance of any robotic ultrasonic inspection system depends on the engineering decisions made long before the equipment is built. Probe selection, scan geometry, path optimisation and inspection qualification are NDT application challenges rather than purely mechanical ones.

Altair Systems places NDT expertise at the centre of every system design. Our engineers understand inspection standards, material behaviour and defect populations, enabling us to build inspection systems that deliver reliable detection performance from the first day of operation.

We partner with clients throughout the entire system lifecycle — from application review and scan plan simulation through system build, factory acceptance testing, commissioning and long-term technical support.
