RISKWISE TM adopted by CRIEPI of Japan

The Central Research Institute of the Electrical Power Industry (CRIEPI) of Japan has become an Associate Partner licencee of RISKWISE. CRIEPI's role is to support the twelve Japanese power industries in research and development together with consulting services. Two members of CRIEPI visited TWI for training on RISKWISE for Boilers in early 2004.

Nuclear plant dissimilar metal weld project is successfully completed

ADIMEW, a major European project on the safety of welds between dissimilar metal pipes in pressurised water nuclear reactors has just been completed. The project investigated the stability of a large defect in the weld buttering joining ferritic and austenitic pipes subject to bending loads. TWI contributed to this project by determining the fracture properties of the buttering material, measuring the surface residual stresses in the weld and successfully predicting the growth behaviour of the defect using advanced finite element and fracture mechanics analysis.

Farnborough 2004

TWI will be exhibiting at the Farnborough Air Show between 19 and 25 July 2004 at Booth F21 in Hall 4. Further details may be obtained from Richard Freeman.

Plastics welder certification - advances in the Emerald Isle

The first ever CSWIP plastics welding examinations in butt fusion and electrofusion welding have just been conducted by TWI in the Republic of Ireland.

Commissioned by civil engineering firm Thomas Swaine and Sons based in Enniscorthy, County Wexford, the exams were taken by four employees, already experienced in polyethylene pipe welding.. They received pre-examination training before taking both written and practical assessments. Certification, aligned to BS EN 13067, was necessary for securing contract work with the local council.

The Certification Scheme for Welding and Inspection Personnel (CSWIP) is already a recognised qualification in Ireland, for those involved with the welding of geo-membrane liners, on landfill and environmental projects.

Wider take up of the scheme is expected across the utilities and civil engineering sectors as clients specify certification in their contracts to ensure the quality of workmanship where pipe welding is involved.
