Failure Case Studies of Weldable Equipments- knowledge base model

The reliability of welded construction during exploitation is an important due to safety of people, protective environments as well as material goods. One of approach to improve reliability of welded constructions is learning on former failures of welded constructions. Usually failures of welded constructions as well as the knowledge base model about accessible failures of welded constructions were explained in this paper. Case studies of failures at welded constructions are very important during education of students as well as engineers from practice. Recognising with failures cases and their analysis will improve reliability of welded construction currently in service, and also a new constructions. The example from practice-wrong chosen post weld heat treatment parameters at normalization of chamber preheater of vapour boiler plant were alsoexplained. Therefore, the models of safety (reliability) of welded joint on constructions were explained, as well as the models of base material weaking due to welding at welded joint position, by especially accent on the probablistic to determine the reliability of the pressure vessel.
