Abstract: PROBLEM TO BE SOLVED The present invention is directed to provide a high-quality fuel rail for high-pressure direct-injection internal combustion engines, in which an injector holder and a fastening bracket are directly attached to a main body of the fuel rail, and has advantage that even if thermal deformation occurs at the time of temporary fitting or brazing when assembling the rail, positional accuracy of the injector holder can be assured, which results in having an excellent sealing property. MEANS TO SOLVE THE PROBLEM The present invention also relates to a fuel rail for high-pressure direct-injection internal combustion engines, in which components of the fuel rail for direct-injection internal combustion engines are made of steel or stainless steel, and the components are reciprocally joined by brazing, characterized in that the components joined by brazing are finished by cutting work and/or burnishing processing after the brazing step.

Abstract: The present invention provides a submerged arc welding method capable of an attempt to enhance toughness of a welded zone with low heat input and an attempt to decrease a weld reinforcement height by suppressing excessive melting of a wire, and capable of achieving a deep depth of penetration and a wide bead width. In the submerged arc welding method, a first electrode at the head in a welding direction has a wire diameter of 2.0 to 3.2 mm and a current density of 145 A/mm 2 or more, second and subsequent electrodes are arranged behind the first electrode in a line, and a groove formed in a steel plate has a two-step groove shape satisfying ¸ B
