The reason of the failure damper of the fabricated fuel rail is analyzed, which was from size comparison, chemical composition, metallographic phase and XRay, and etc. The test method of cracking was described. It comes up with the reasonable improvement measure, which puts the end to the leakage successfully caused by the weld cracking position of the damper.
