| Abstract: | Construction technology of large-scale pipeline and mixing type vertical downwards-welding technology is introduced. Applied effect of mixing type vertical downwards-welding technology is remarkable in central heating main pipe of Taiyuan No.2 thermal power plant, tested crater pass, welding quality measure up to the standard. It cannot be applied extensively in large-scale pipeline welding. |
