To provide a circumferential welding method for a pipe line fixed pipe, which is high in welding efficiency and excellent in welding joint performance.

Welding is carried out by running a welding head along an end part by an upward symmetrical sequence; wherein the welding current is 150-250A, and a flux cored wire is used, and a V-shaped groove is 10-40 degrees in a groove angle. It is preferable that a solid wire is used for the first layer welding, and penetration welding is carried out by using a copper backing as a backing material. The flux cored wire is preferably 1.2 mm or more in diameter.
