In the construction of pipeline engineering, the application of welding technology is very important. Welding technology is directly related to the construction quality of pipeline engineering! It can also ensure the safety and stability of the project

With the continuous development of the current social and economic construction, the construction of pipeline engineering has also played a more and more important role. This is because pipeline transportation is directly related to the use of energy and has a close relationship with the production and life of human society. In the construction of pipeline engineering, The welding of long distance pipeline is a very complex and important work, because the welding of long distance pipeline will directly affect the safety and stability of pipeline in the future Therefore, in order to ensure the good operation of pipeline engineering, it is necessary to pay attention to pipeline welding

Technical points:

According to the actual application of all position automatic welding technology for long-distance pipeline, the application of this technology needs to go through four links, namely, nozzle cleaning, nozzle trimming, welding parameter input and welding. Pipe orifice cleaning is essential in the welding process of long-distance pipeline. This is because the pipes that need to use automatic welding technology for construction usually have the characteristics of large pipe orifice diameter and thick pipe wall. Therefore, in order to ensure the welding quality, it is necessary to clean the nozzle. The area to be cleaned shall be within 100mm of the pipe orifice and its vicinity. The sundries to be cleaned include dust, oil, rust, etc

After cleaning the nozzle, it is necessary to trim the nozzle. This is because if the groove angle of the nozzle or the hardness of the thickness of the blunt edge of the nozzle is too high, the welding track will be damaged! Only the quality of welding work can be guaranteed! Only in this way can the pipeline project play a greater role in the future. (Shen Shaofeng)
