摘　　要：通过室内浸泡、应力腐蚀试验对B610E高强储罐钢所用不同焊接方式在石油沉积水中的耐蚀性进行研究。结果表明,B610E气体保护焊材料的耐蚀性最好,将Q235+B610E埋弧平焊对接后,由于存在电偶对,耐蚀效果最差。在石油沉积水中,B610E埋横焊具有中等SCC抗力,B610E气体保护焊、B610E气电立焊以及B610E+Q235埋弧平焊对接具有高的SCC抗力。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.
