| Abstract: | Surfacing technology of Ni-alloy to improve the sealing face of valve was introduced. Using the MIG surfacing method, Ni-alloy was deposited evenly on the sealing face of valve to enhance the performance and prolong the life of the valve. Special welding technology was designed according to 3D structure of the sealing face. The automatic welding machine and control system were made to perform the complex surfacing technology, which met the need of the project. |
