| Abstract: | The wehting tests were carried out for the welding porosity in Cu-Ni alloy tube of drilling platform, so as to ana- lyze the causes of wehl porosity and to work out tile preventive methods. The research showed that after prevention from improving the shielding gas, sealing devices and method, welding operation and so on, the radiographic testing （RT） is OK and there are no porosity in the welding. So, the welding process of alloy tube CuNi90/10 was qualified and applied in the production of Cu-Ni alloy tube welding. |
