| Abstract: | 2 kinds of duct-board were adopted for 650 MW unit condenser at Qingshan Nuclear Power Station,phase II expansion project.Higher requirements for welding quality are needed due to longer weld beads(longest more than 4 m) on the board.The paper introduces key welding points and the welding essentials on duct-board installation Technical measures of deformation control on duct-board in the process of welding were investigated. |
