压力管道是一种特殊管道,这种管道内部或外部需承受一定的压力,管道内部运输的介质具有易燃、易爆性,有时还需运输有毒介质。并且在压力管道建设中,需要进行大量的焊接工作,因此压力管道焊接过程中需要做好对焊接机械设备、焊接工艺以及焊接环境等进行质量控制,从而确保压力管道焊接质量。基于此,本文分析了影响焊接质量的主要因素,对压力管道的焊接工艺及其质量控制进行了探讨。
Pressure pipe is a special kind of pipe, which must withstand some pressure inside or outside the pipe. The medium transported inside the pipe is flammable and explosive, and sometimes it needs to transport poisonous medium. And in the construction of the pressure pipeline, a large amount of welding work is required. Therefore, the quality control of welding machinery, welding process and welding environment needs to be done in the process of pressure pipeline welding to ensure the welding quality of the pressure pipeline. Based on this, this paper analyzes the main factors affecting the quality of welding, the pressure pipe welding process and quality control were discussed.
