水电机组安装检修质量,直接影响着水电机组运行的安全性、可靠性及经济性。在水电机组安装检修中其焊接形式多采取全位置焊接,这种焊接方式对自动焊应用造成了一定限制。通过对水电机组安装检修焊接特点的分析,以结构钢、不锈钢、高锰奥氏体钢及异种材料为重点,对其安装检修中焊接焊条的选择进行研究,以提高水电机组安装检修质量,保障水电机组运行综合效益。
The installation and maintenance quality of hydropower units directly affects the safety, reliability and economy of hydropower units. In the hydropower installation and maintenance in the form of welding to take more all-position welding, this welding method for automatic welding caused some restrictions. Through the analysis of the characteristics of installation, repair and welding of hydroelectric units, the selection of welding electrodes in the installation and maintenance is mainly focused on structural steel, stainless steel, high-manganese austenitic steel and dissimilar materials to improve the quality of installation and maintenance of hydroelectric units Comprehensive benefits of hydropower unit operation.
