10:10 ISO/TS 18166 NUMERICAL WELDING SIMULATION: EXECUTION AND
DOCUMENTATION
Simon Smith, Technical Manager, TWI
• ISO standards for an area are developed and maintained by Technical Committees (TC). ISO/TC 44
covers “Welding and Allied Processes”
• The Working Groups (WG) of a committee are responsible for the drafting documents. ISO/TC 44/
WG5 covers “Welding Simulation”
• ISO Technical Specifications (TS) represent a technical consensus of a WG. WG5 prepared TS 18166
to provide high level recommendations for simulations of welding

MANUFACTURING USING OPTICAL FIBRE SENSORS
Matthieu Gresil, School of Materials, University of Manchester
• Understanding quality and mechanical properties of a composite material post production
• Using optical sensors to measure the residual strain and changes in temperature
• Acquisition of data to characterise the strain profile during the manufacture process
11:40 RESIDUAL STRESS IN POWDER BED LASER MELTING
Chris Sutcliffe, Senior Lecturer Centre for Materials and Structures, University of Liverpool
• Measurement methodologies
