| Abstract: | The welding quality of thick-walled pipeline of thermoelectric power station is related with the unit safe operation.The author introduced the technology characteristic of two kind of radiographic testing of middle welded joint,and so on with the film being located directly close to the weld or close to the tube wall respectively, and analyzed their effect on the testing quality.Through the contrast experiment,the paper showed the flaw detecting ability of the two methods. |
