针对小口径管道传统的人工焊接方法效率低下、劳动强度高、存在安全风险且对操作工人技能要求高,难以满足现代工程的需求,设计了一款小口径管道内焊接机器人.该机器人能够在管道内部自主移动,利用精密的机械结构实现高质量的自动化焊接.机器人主要由行走机构、涨紧机构、焊枪升降机构、焊枪回转机构、送丝机构和智能控制系统等部分组成,通过智能控制系统来精确控制各个电机驱动单元,实现全电动的焊接作业.与现有外焊设备相比,这款内焊机器人能有效避免外部环境干扰,提升焊接稳定性,尤其适用于空间受限、难以采用传统焊接方法的施工环境.此设计不仅提升了自动化焊接的灵活性,还展现了焊接技术的智能化发展趋势,为油气管道建设提供了技术支持.

干式高压焊接是既能保证焊接质量又易于实施的海底管道维修方法.基于目前的自动化技术水平和海管坡口制备难度大的现实,提出了基于高级焊工焊接知识和潜水员水下工作技能的遥控海底管道维修焊接策略.研制了一套干式高压环境管道全位置焊接机器人及其分置于水面母船甲板和水下干式舱的机器人焊接控制系统,研制了分别用于场景、坡口和焊缝的视觉监视系统,以及计算机远程信息采集监控系统,它们与水下干式舱系统一道构成了水下干式管道维修系统.还研究了干式舱充气气体种类、焊接电源特殊性和舱内引弧问题.利用先期在干式高压焊接实验室获得的海管焊接工艺完成了海上焊接维修试验,焊缝质量良好.Abstract: Among the available underwater pipeline repair methods, hyperbaric TIG welding technology may be the easier one to obtain better joint quality. Due to the low automation level and the bevel preparation difficulty, the repair welding should be conducted based on both the welding knowledge of the welder on deck and the operation skill of the diver. A tele-operated robot for all position hypetharic pipe welding was developed. In the specified case of underwater welding, the process was controlled by a surface based operator, a clear and real time image of the arc as well as the image of groove location were required. An observation system of three cameras for chamber, groove and weld was also developed respectively. All the necessary message of vision, welding current and arc voltage were collected and transferred to the surface by the developed computerized information system. The underwater pipeline maintanence system consists of the welding robot, observation system, the informarion system, together with the habitation. The chamber gas type, the welding power source and arc striking were also studied. With the welding proceedure developed in the hyperbaric welding laboratory, a good weld was obtained in a underwater pipe repair welding test at Bohai sea. 相似文献
