以JB4708-2000《钢制压力容器焊接工艺评定》标准释义为基础,构造焊接工艺评定流程模型,重点对焊接工艺评定的必要性作出判断,解释并例举对标准中规则知识的总结和表达,并写入SQL(结构化查询语言语句),建立知识库。实现对所要求的焊接条件根据替代规则对PQR(焊接工艺评定报告)数据库进行合理搜索,得出符合输入条件的PQR。
Based on the definition of JB4708-2000 Standard for Assessment of Welding Process of Steel Pressure Vessels, the process model of welding process qualification is constructed, the judgment of the necessity of welding process evaluation is made, the summary and expression of the rule knowledge in the standard is explained and exemplified, And write SQL (Structured Query Language), the establishment of knowledge base. Achieve the required welding conditions The PQR (Welding Procedure Qualification Report) database is properly searched according to the substitution rules to obtain the PQR that meets the input conditions.
