Fatigue testing and assessment services

Welded joints have poor fatigue properties which must be allowed for in design. TWI played a pioneering role in establishing fatigue design guidance for steels and aluminium alloys, now incorporated in British and International Standards. Our services include:

  • Interpretation of fatigue design rules

  • Assessments using numerical modelling, design codes and experimental data

  • Guidance on joint design

  • Specification and application of fatigue life improvement processes

  • Fatigue testing of welded and unwelded joints and specimens

  • Interpretation of testing results and comparison with TWI's extensive fatigue database

  • Detailed investigation and interpretation of service failures

  • Rapid deployment of experts for site investigation and recommendations on repair
