Advanced Testing for Welded Structures in the UK

At LTi Metaltech, we provide comprehensive destructive and non-destructive testing (NDT) services to verify the integrity, performance, and safety of welded structures. Operating from our state-of-the-art facility in Oxfordshire, we combine advanced inspection technology, qualified CSWIP-certified personnel, and rigorous quality assurance protocols to ensure every component performs flawlessly - even under the most demanding vacuum, pressure, and temperature conditions.

Our extensive testing capability underpins our reputation as a leading UK manufacturer of high-integrity welded structures, supporting critical sectors including nuclear, fusion, energy, and healthcare.

Our Non-Destructive Testing Services:

Our non-destructive testing methods evaluate weld quality and performance without causing damage, ensuring structural integrity, safety, and compliance throughout the fabrication process.

We offer a wide range of NDT techniques, including:

  • Radiography – advanced imaging for internal weld analysis and defect detection.
  • Dye Penetrant Testing (PCN Level II) – proven surface defect identification for stainless steel and other materials
  • Helium Leak Testing – verifying airtight seals for vacuum and pressure-critical systems.
  • Hydrostatic Pressure Testing – confirming pressure integrity under realistic load conditions.
  • Vacuum Pressure Testing – validating component performance in low-pressure environments.
  • Visual Weld Examination (CSWIP 3.1) – detailed inspection by certified welding inspectors.
  • Positive Material Identification - quickly and accurately identify the chemical composition and grade of a metal alloy.

These non-destructive inspection services allow us to identify imperfections early, maintain compliance with international welding standards, and deliver complete confidence in product reliability.

Comprehensive Destructive Testing Methods:

For a deeper understanding of material behaviour and weld performance, our destructive testing procedures subject welded assemblies to controlled stress, strain, and environmental exposure.

Our portfolio includes:

  • Tensile Testing – measuring weld and material strength.
  • Impact Testing – evaluating toughness and resistance to sudden loads.
  • Bend Testing – confirming ductility and flexibility under stress.
  • Fracture Testing – analysing crack growth and propagation.
  • Macro/Micro Examination – detailed assessment of weld penetration and grain structure.
  • Hardness Testing – determining resistance to deformation and wear.

These tests provide quantifiable data to validate the mechanical integrity, durability, and safety of our welded components - ensuring every assembly is fit for purpose in high-pressure or safety-critical environments.

Commitment to Quality and Certification

At LTi Metaltech, quality assurance is central to everything we do. All coded welding procedures and associated testing activities are:

  • Validated by qualified welding inspectors
  • Approved and verified by independent third-party bodies

This approach guarantees traceability, compliance, and confidence across all testing and certification activities, in full alignment with ISO standards and client-specific requirements.
