摘要：
The cathode protection method is a very useful corrosion protection technology for the underground pipelines. However, it has some problems that hydrogen generated by electrochemical reaction on the wet surface of the pipelines is attacked into the pipe weld, and make degradation of their mechanical properties. Therefore, in this study, welding residual stresses around of the X65 pipe weld, which is generally used as a material of the gas pipelines, were previously calculated. And next, by using the cathode protection method, artificially degraded the X65 pipe weld including base metal, assessed its influence on the mechanical properties of the X65 pipe weld.
