The The Development of Automatic Controlling System for Pipelines Welding Abstract While traditional hand welding and semi-automatic welding can’t meet the demand of welding quality and production efficiency for modem pipeline industry,full automatic pipelines welding is bound to become a new widely- used technology,SO a kind of automatic controlling system for pipelines welding is developed，ofwhich industry PC is base and PMAC motion controller is core． In this paper,the hard ware and the soft Ware of the controlling system are completed．The work of designing hard ware includes selection of the electric components，design ofthe interface circuiL design and layout ofthe control box， structure design and circuit design of the handle box．The software includes the interface between machine and man，large welding parameters database， precious PID feedback of welding current and voltage，the program of automatic welding and handle interfere．The experiment shows that this system is precious and reliable。 With walking mechanism， weaving mechanism and lifting mechanism，The automatic welding machine can accomplish continuous multi—layer welding automatically and improves the welding quality and production efficiency of the big and thick pipelines greatly,SO it meets the demand of modem pipeline industry and has hi曲engineer application value． Because this system carl suit different welding methods throu曲matching different arc-welding powers，it is a comlTlon system． Key words：pipelines welding PMAC motion controller Industry PC interface between machine and man 独创性声明本人声明所呈交的论文是我个人在导师指导下进行的研究工 独创性声明 本人声明所呈交的论文是我个人在导师指导下进行的研究工 作及取得的研究成果。尽我所知，除了文中特别加以标注和致谢 的地方外，论文中不包含其他人已经发表或撰写过的研究成果， 也不包含为获得石油大学或其它教育机构的学位或证书面使用过 的材料。与我一同工作的同志对本研究所做的任何贡献均已在论 文中作了明确的说明并表示了谢意。 签名：盏鱼羹 山。；年 6月 r日 关于论文使用授权的说明 本人完全了解石油大学有关保留、使用学位论文的规定，即： 学校有权保留送交论文的复印件及电子版，允许论文被查阅和借 阅；学校可以公布论文的全部或部分内容，可以采用影印、缩印 或其他复制手段保存论文。 (必威体育官网网址论文在解密后应遵守此规定) 学生签名： 整鱼篡 如；年 ；月 }日 导师签名：蕴§竺苎导师签名：缸01耋 ≯哆年≯哆年 ∥月手 月 歹目手目 石油大学(华东)硕士论文 石油大学(华东)
