摘要
为进一步改进埋弧焊焊缝形状及提高焊接质量,分析了影响埋弧焊焊缝形状控制的五个工艺措施,建立了焊缝形状曲线的数学模型,利用VB语言编制描述焊缝形状的模块,对焊缝形状分段描述并得到描述的拟合方程,再建立焊缝形状评价系统,对拟合效果及焊缝形状进行评价,最后利用数据库系统和专家系统,进行焊接参数优化,选出最合理、最理想的焊接方案,最终实现焊缝形状的改进和焊接质量的提高。焊缝形状控制数据库系统和专家系统还可用于现场埋弧焊焊接工艺的优化。
In order to further improve the weld shape of SAWH pipe and welding quality, it analyzed 5 process measures affecting SAWH pipe weld shape control in this article, and set up mathematical model of the weld shape curve. It used VB language to establish the module of the description of the welded joint shape, described weld shape subsection, obtained the fitted equation, and set up weld shape evaluation system. It utilized database system and expert system to optimize welding parameter, and select the most reasonable and the most ideal welding scheme, finally realized the weld shape improvement and welding quality enhancement. The database system of weld shape control and expert system can also be used for on-site submerged arc welding process optimization.
