TWI offers premium quality failure investigation and root cause analysis services. With over 50 years of troubleshooting expertise and thousands of successful investigations, TWI has a long and distinguished history in determining the mechanisms and root causes of some of industries most costly and dramatic failures.
TWI's unique combination of knowledge in materials, fabrication and through-life service assessment and performance has built an enviable reputation in troubleshooting the most difficult of failures. Our experts work routinely for fabricators, industrial managers, lawyers and loss adjusters, and can provide key interpretation to the results of any investigation.
TWI has state of the art facilities for diagnosing failures, from non-destructive evaluation using X-ray tomography through to destructive examination using advanced scanning electron microscopy. Through the combination of the specialist expertise of its 200 engineers and its access to cutting-edge technology, TWI can provide the right information in the right time frame.
TWI can help remediate the impact of a failure by:
- Interpretation of the failure location and service data, including on-site review
- Examining the parts and determining the failure mechanism(s)
- Root cause analysis, including design, fabrication, transportation, installation and service
- Simulation of the service conditions to establish critical parameters at which failure will occur
- Definition of safe conditions for remaining intact components
- Establishing a non-destructive evaluation strategy for remaining components
- Remedial advice for avoidance of further failures, including design and fabrication review for replacement components and mitigation strategies for existing components.
We provide:
- Expert, multidisciplinary interpretation of data
- Failure mode characterisation by light optical and scanning electron microscopy
- Microstructure and defect characterisation, with a particular strength in weld microstructures
- Stress analysis and numerical modelling, including welding residual stress
- Engineering critical assessment
- Expert knowledge of microstructure-property relationships, including the influences of welding and manufacturing processes
- Development of non-standard test methods to produce new microstructure-property relationships where existing data are inadequate to ensure future fitness-for-purpose
- Contribution to root cause investigations
- Expert witness services in a wide range of disciplines, including welding engineering, metallurgy, corrosion, fracture mechanics, fatigue, asset integrity management and non-destructive examination
