焊接金相组织自动定量识别软件系统

在ＭＳＣ／Ｃ＋＋７．０集成环境下成功的开发了一个焊接金相组织的自动定量识别软件系统（ＷＭＳＱＲＳ）。该系统根据焊接金相组织的灰度特征和几何特征创造性的抽取了多个关键性的特征参数，利用模式识别原理建立了相应的识别函数和最小距离法分类器。利用该能够较好的对低碳钢、低合金钢焊接金相组织进行定量识别分析。其识别的可靠性、准确性和再现性能满足焊接定量金相的要求。这对于建立焊接接头成分、组织性能之间的定量关系

Automatic Quantitative Recognition Software System for Microstructure of Welded Joints

In this paper, an automatic quantitative recognition software system for welding microstructure (WM SQRS) has been successfully developed under the integrated compiling environment of Microsoft C/C++7.0. On the basis of gray character and geometrical pattern features of welding microstructures, several key characteristic parameters have been creatively extracted, and the correspondent recognition function and a minimum-distance classifier have been constructed. Using this system, quantitative recognition and analysis of microstructures in welded joints made of the mild and the low-alloy steels can be done automatically. Its accuracy, reliability and reappearance can satisfy requirements of quantitative analysis of welding microstructures. The software has great theoretical and practical significance in setting up the quantitative relationship among the compositions, microstructures, and mechanical properties of welded joints, selecting appropriate welding materials and suitable processes, improving welding quality and developing quantitative welding metallurgy.
