This one day event was held on 20 May 2015 at Tata Steel’s Swinden Technology Centre in Rotherham.
The presentations addressed issues relating to establishing repeatable material characteristics, controlling and integrating them into the predictive and manufacturing of steel products.
9.00am Registration, Tea and Coffee
9.20am Introduction – Norman Thornton, EIS
9.40am Measuring Total Strain – John McCarthy, MAPS
Use of MAPS to measure material condition and total strain with examples of welded coiled tubing
etc. Total strain including residuals are frequently not allowed for in prediction and testing and vary in manufacture.
10.40am Tea and Coffee
11.00am Welded Joints – Simon Smith, TWI
Performance testing of thick-walled welded pipes for demanding applications in the offshore oil and gas sector, including: Toughness issues of welds, predictions and effect of residual stresses and implications to overall pipe integrity; Characterising the effect of welding, forming and in-service strains on pipe performance; Simulating test conditions for strain-based design of pipelines.
12.45pm Tour of Tata Steel facilities with discussion of technology in each area.
1.45pm Material Properties at High Strain Rates – David Norman, Tata Steel
Establishing real material characteristics for high strain rate loading of steel components. Impact and collision performance requires accurate material data at these strain rates and must include the manufactured condition.
2.45pm Tea and Coffee
3.00pm Structural validation of off-highway vehicles using field data – Dr Colin J Dodds, Dodds and Associates
In the development of specialized off-highway vehicles, only a limited number of prototype vehicles and components are available for structural validation. The service loading is variable and uncertain and often the weld quality leaves a lot to be desired. A validation program, designed to achieve a given reliability and based on limited field measurements with 3-4 prototypes and the use of “Gassner” SN curves has been developed and implemented. The results are compared with warranty data and subsequent customer usage.
4.00pm Q&A Session
Open forum debate on issues raised and possible creation of projects to establish needed information.
4.30pm Closing Comments
