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.
