| Abstract: | In order to study the effect of double-resistant steel pipe resistance against hydrogen induced cracking and sulfide stress corrosion cracking resistance of factors,a double resisting steel tube adopts double"V"groove form,through different line energy under manual arc welding process after welding,the mechanics properties of the welded joint,the welding crack performance,the highest hardness test,metallographic were analyzed.The test was carried out using the test methods of NACE.It was found that hydrogen sulfide stress corrosion cracks were mostly distributed along granular bainite grain boundaries and uneven weld microstructure,and the higher the hardness,the higher the crack sensitivity is. |
