摘要
针对焊接结构完整性研究的需要,建立了焊接数据管理数据库系统,并在此基础上结合BS7910评定方法建立了焊接缺陷评定专家系统。该系统采用模块化设计思路,采用面向对象设计方法,对整个系统进行总体设计。该系统实现了焊接工艺数据的信息化管理,可进行多种焊接方法焊接工艺数据的管理和查询,结合专家系统的合于使用评定方法,可对含缺陷结构进行2个级别的安全评定和裂纹容限尺寸计算。
Aiming at study on the integrality of welding structure, a database is established which can manage and search welding data. An expert system for assessing of the acceptability of weld flaws based on BS7910 is established in addition, which could gain knowledge automatically from the database. The system is designed with modular programs and object oriented method. Application of this system can realize information management of welding process data. It can manage and search data of joints and base metals in several welding methods, and can be used for safe assessing on welded structure with flaws and calculation of size of crack tolerance.
