【摘要】 焊接工艺评定在重要结构的生产制造过程中占有十分重要的地位，它是焊接质量的保证。作者结合实际课题—北京巴威公司焊接部门的焊接工艺评定管理系统，将专家系统理论、焊接工艺评定管理技术与数据库技术、网络技术等集于一体，以Windows2000 Server为网络操作系统、MS SQL Server2000为数据库系统、MSVB与ASP为应用程序开发工具，构造了基于用户界面的“网络化智能焊接工艺评定管理系统(IWPQMS)”。IWPQMS遵循先进、经济、安全、高效、可靠、易维护的设计原则，结合巴威公司焊接部门业务特点，采用C/S和B/S相结合的体系结构，有效地利用了巴威公司内部的计算机资源和网络资源。IWPQMS可以使工艺人员通过网络进行焊接工艺评定报告的制定、审批、资源信息查询等操作，同时，将专家系统应用于焊接工艺评定的制定过程中，减轻工艺人员的工作量，提高设计效率。本文详细介绍了IWPQMS的基本组成、原理以及具体实现方法。IWPQMS对于实现计算机辅助工艺设计的智能化具有一定的前沿性理论价值和实际意义。更多还原

【Abstract】 Welding Procedure Qualification occupies an important position in the manufacture process of big container, and is also the guarantee for the quality of welding. In this paper, expert system, welding procedure qualification technique, database technique and network technique were integrated a system to accomplish Network Based Intelligent Welding Procedure Qualification Management System (IWPQMS) based on the user-interface for a practical project, Welding Procedure Qualification Management System for the welding department of Beijing B&W company. Windows2000 Server, MS SQL Server 2000 and MSVB & ASP were used as the network operating system, the database system, and the developing tools of its application programs in IWPQMS, respectively.According to the character of B&W company’s welding department, on the basis of the design principle of advancement, economy, efficiency, reliability and easy operating, a compound system structure of C/S and B/S that can fully utilize the computer and network resources of the B&W company is used in IWPQMS. Engineers can operate the establishment, examination and revision, resource information query of the welding procedure qualification via network by means of IWPQMS. At the same time, the workload of engineers can be decreased, and the efficiency of design can also be increased due to the adoption of expert system in the establishment of welding procedure system.In this paper, the main structures, principle and achieving process of IWPQMS were introduced in detail. IWPQMS has a very important significance not only to the theory research but also to the practical project for the intelligent computer aided procedure design.更多还原
