Abstract
A Cooperative Research Centre project "Welding of Thermally modified Structures" was commenced in June 1993 with support from ANSTO, CSIRO, BHP, University of Wollongong and the CRC for Materials, Welding and Joining. The main aims of the project are to quantify the effects of performing repair welds on materials which have operated for extended periods at elevated temperature. Welding is an increasingly used method for performing repairs, replacements, retrofits and modications to elevated temperature plant, however, the effects of these repairs on the ultimate life of a component are poorly understood. This paper presents details of the three ex-service materials chosen for the project, a carbon steel and two low alloy steels. Assessments have been made of their ex-service condition and a series of repair welds manufactured in preparation for a comprehensive testing and assessment program over the next 2 years. Work is also presented on development of new methods of assessing materials and components both destructively and non-destructively, along with new methods of modelling welded components in high temperature service.
