| Abstract: |
| The corrosion-resistant performance of different welded joints of B610E high-strength tank steel in the deposited water of petroleum was investigated by indoor soaking test, and stress corrosion test. Results showed that B610E gas shielded welding materials has the best corrosion-resistance; submerged arc welding of Q235+B610E pairing is the worst due to galvanic corrosion effect; in the deposited water of petroleum, B610E submerged horizontal welding with medium resistance to SCC; B610E gas shielded welding, B610E electro-gas welding and B610E+Q235 submerged flat welding has high SCC resistance. |
