| Abstract: | RA330 alloy is a type of iron-nickel-chromium heat-resisting alloy, the phenomena of welding hot crack will be easily appeared. In this paper, proper welding material and feasible welding method was chosen based on RA330 alloy＇ s weld-ability analysis; besides, welding procedure qualification test was carried out according to NB/T47014-2011 ＇welding procedure qualification of pressure-bearing equipment＇, and satisfactory welding parameter was achieved from the test. The test result shows that RA330 alloy welded with RA330-04 welding wire by TIG process could form a perfect weld joint. At the same time, this paper also summarized RA330 alloy welding characteristics, which will be a reference or guidance for its welding operation. |
