Sonatest UT Devices for NDT - NDTScan

Overview

NDTScan relies on Sonatest Ltd ultrasonic systems for flaw detection, thickness gauging, and weld integrity testing across structural steel, pipelines, vessels, and fabrication works. Sonatest offers a range of portable, high-performance instruments that meet EN12668 and ISO 17640 standards — making them ideal for UK and international NDT projects.

We use Sonatest Ltd equipment on construction sites, shipyards, bridges, and manufacturing plants where structural assurance and code compliance are non-negotiable.

Continuous Innovation in Ultrasonic Inspection

Sonatest is a pioneer in phased array, TOFD, and conventional UT technologies. Their rugged, field-optimised instruments deliver fast, reliable data even in challenging conditions.

Our Sonatest Ltd UT Systems

  • Sonatest Veo3: Phased array ultrasonic flaw detector with real-time imaging and TOFD capabilities. Used for critical welds, corrosion mapping, and composite inspection.
  • Sonatest Sitescan D-50: Rugged and portable A-scan flaw detector for basic UT tasks — ideal for general wall thickness checks and flaw localisation.
  • Sonatest Prisma: Advanced multi-mode flaw detector with phased array, conventional UT, and TOFD in one system — used in complex integrity assessments.
  • Corrosion Gauging Kits: Includes transducers, calibration blocks, and surface prep tools for reliable metal thickness checks.
  • UTLink Software: For data backup, analysis, and traceable reporting — essential for QA and compliance documentation.

Why We Use Sonatest

Sonatest systems are accurate, code-compliant, and built for the field. Their performance under real-world conditions, combined with advanced software support, makes them ideal for daily flaw detection and structural monitoring tasks.

Other Equipment in Use

We also use Olympus and Eddyfi for niche or automated NDT tasks, but for portable ultrasonic inspections, Sonatest is a top performer.

Ultrasonic Flaw Detection UK Services Built on Field-Proven Sonatest Systems

NDTScan delivers expert ultrasonic flaw detection UK services using advanced Sonatest Ltd instruments — trusted for structural assurance across civil, marine, industrial, and energy sectors. Whether scanning welds on bridges, measuring thickness loss on pipelines, or evaluating fabrication defects in structural steel, Sonatest equipment provides us with the reliability, portability, and code compliance essential to non-destructive testing in demanding environments.

Built around real-time A-scan, phased array (PAUT), and time-of-flight diffraction (TOFD) methods, Sonatest tools allow our technicians to locate, size, and characterise subsurface flaws with clarity and traceability — on-site and under pressure.

From new-build fabrication to life-extension maintenance inspections, Sonatest technology supports NDTScan in delivering critical ultrasonic testing services across the UK and beyond.

Designed for the Realities of On-Site NDT

Ultrasonic testing rarely takes place in controlled conditions. Whether we’re working in exposed coastal facilities, mid-construction on steel frames, or alongside fabrication teams on tight programmes, our Sonatest systems are built to withstand real-world conditions while producing repeatable, standards-compliant inspection results.

We use these systems for:

  • Butt weld inspection in pressure vessels and pipelines

  • Thickness mapping in ageing infrastructure

  • Corrosion tracking in offshore and subsea structures

  • Crack detection in structural steel during construction

  • Defect validation during manufacturing QA

  • Composite and laminate testing in aerospace or renewables

Each application is backed by calibrated equipment, qualified technicians, and structured reporting aligned to ISO, ASME, EN and AWS codes.

Versatile UT Platforms for All Defect Scenarios

Our Sonatest instruments are configured for flexibility — allowing our technicians to switch between conventional UT, phased array, and TOFD modes depending on the inspection scope and material profile.

Veo3 — High-Performance Phased Array UT

  • Combines phased array, TOFD, and FMC/TFM technologies

  • Features advanced real-time visualisation for weld inspection

  • Supports multi-element probes and full waveform recording

  • Used for coded weld inspections, high-resolution corrosion mapping, and defect sizing

  • Compatible with industry-standard probes and custom configurations

Sitescan D-50 — Portable A-Scan Flaw Detector

  • Ultra-rugged conventional UT unit for site-ready inspections

  • Ideal for general purpose flaw detection and thickness measurement

  • Intuitive controls, full digital readout, and high signal clarity

  • Frequently used for steel fabrication validation, weld toe scanning, and basic QA/NDE applications

Prisma — All-in-One Multi-Mode Flaw Detector

  • Combines phased array, TOFD, and conventional UT in one field system

  • Used for complex inspection routines including nozzle welds, multilayer laminates, and critical access areas

  • Fully portable with touchscreen interface and robust enclosure for harsh conditions

  • Supports traceable digital workflows and multi-format data export

Complete Toolkits for Corrosion and Wall Thickness Surveys

We also operate Sonatest thickness gauging kits designed to support:

  • Routine corrosion monitoring on pipelines and vessels

  • Wall loss trending in tanks and civil infrastructure

  • Minimum thickness validation for asset integrity thresholds

  • Pre-welding inspection for parent material confirmation

These kits include single- and dual-element transducers, calibration blocks, and surface prep tools — ensuring we deliver precise, repeatable thickness readings in line with EN 14127 and ISO 16809 standards.

Data Integrity and Digital Reporting with UTLink

All inspections using Sonatest systems are backed by UTLink software, allowing us to:

  • Download and store A-scan/PAUT data securely

  • Annotate defects, measurements, and weld locations

  • Generate PDF or CSV outputs for QA documentation

  • Maintain a traceable inspection record aligned to ISO 9001

  • Integrate with client QA systems or asset registers

This digital workflow ensures that every ultrasonic test we perform can be validated, reviewed, and audited — reducing risk and simplifying compliance across complex inspection programmes.

Typical Use Cases for Ultrasonic Flaw Detection UK

NDTScan provides ultrasonic testing services using Sonatest systems across:

  • Steel frame erection and structural steel inspections

  • Oil & gas pipelines (onshore and offshore)

  • Storage tanks, silos, and pressure vessels

  • Civil infrastructure including bridges and gantries

  • Marine and shipping applications including hulls and prop shafts

  • Power generation — boilers, turbines, and energy networks

  • Rail industry rolling stock and maintenance facilities

Whether you’re meeting compliance deadlines, investigating known defects, or validating third-party fabrications, our ultrasonic NDT services offer high-fidelity data delivered to schedule and specification.

Why Sonatest is Core to Our UT Strategy

NDTScan chooses Sonatest Ltd instruments because they offer:

  • Unmatched reliability in the field

  • Accurate, standards-compliant measurement capability

  • Flexible inspection modes to match evolving site needs

  • Intuitive interfaces that support technician productivity

  • Advanced data logging and traceability features

The combination of portability, performance, and durability makes Sonatest systems ideal for structural inspections under operational or environmental constraints — giving us and our clients confidence in every scan.

Integration with Other NDT Methods and Platforms

While Sonatest tools are our go-to solution for manual and semi-automated ultrasonic inspections, we also integrate them with other technologies when required:

  • Magnetic particle or dye penetrant testing for surface-breaking flaws

  • Eddy current or pulsed eddy current for conductive materials

  • Thermographic analysis for near-surface defect screening

  • Phased array systems from Olympus for specialist components

  • Full reporting into digital twin or asset management platforms where required

This ensures a multi-technology approach for comprehensive integrity evaluation — especially where asset criticality or operational risk is high.
