Abstract:

Welds are the most common site of damage in high-temperature components. This involves large costs of control, repair and replacement. This paper discusses this issue from the viewpoint of two end users, i.e. Enel in Italy, and Iberdrola in Spain. General information on the above two organisations, and to the relevance of this subject, is given. After a brief description of the practices they apply to face relevant problems, experiences of failure analysis and testing involving welds, exposed to high temperature, are reported.

More about this publication?

Materials at High Temperatures serves the needs of those who develop and use materials for high temperature applications. It publishes peer reviewed contributions relating to high temperature applications in the power, chemical, engine, processing and furnace industries.
The effects of high temperatures on corrosion, fatigue, creep, strength and wear in alloys, intermetallics, ceramics, refractories and composites are covered. Papers dealing with aspects of materials usage including modelling of behaviour and life prediction will be particularly welcome. The journal has a policy of emphasizing practical aspects and authors presenting results from research programmes are encouraged to relate these, if possible, to actual or potential applications.
