管道水平固定全位置熔化极机动焊接工艺

摘要

Automatic welding of the whole position of the pipeline is to rely on electrical,mechanical and other methods,so that the welding machine driven along the fixed track around the wall movement,through automatic wire feeding and PLC control technology to achieve automatic welding.The purpose of this paper is to improve the welding efficiency on the basis of ensuring the quality of the joint,while reducing the labor intensity of the welder In recent years,the requirements of pipeline welding quality are getting higher and higher in engineering construction,each construction enterprise has carried on a lot of exploration practice and experiment with all position pipeline welding.Through repeated welding test,gradually explore and master the welding parameters and welding methods of all position pipeline welding,which provides a reference and basis for improving the construction efficiency and quality of the all position pipeline welding of the construction site.%管道全位置自动焊接是指在管道相对固定的情况下,依靠电气、机械等方法,使焊接小车带动焊枪沿着固定轨道环绕管壁运动,通过自动送丝以及PLC控制等技术来实现自动焊接.研究管道全位置自动焊的焊接工艺以及焊接设备的目的是在确保接头质量的基础上提高焊接效率,同时降低焊工的劳动强度.工程施工中对管道焊接质量要求越来越高,通过反复焊接试验,各施工企业逐渐摸索和掌握全位置管道机动焊的焊接参数和焊接更领,为提高施工现场的管道全位置焊接施工效率和质量提供了参考和依据.
