The present invention relates to a method for welding an upper rail of a seat track for a vehicle seat and an adaptor bracket for fixing a seat frame, the method comprising the steps of: surface contacting a bottom surface of a plate-shaped coupling face, which forms the lower end part of the adaptor bracket and which is extended to a predetermined length in the longitudinal direction, with a top surface of a plate-shaped horizontal face, which forms the upper end part of the upper rail and which is extended in the longitudinal direction; and welding a bottom surface of the horizontal face that overlaps the coupling face to bond the coupling face and the horizontal face. Accordingly, it is possible to improve the welding hardness of the upper rail of the seat track and the adaptor bracket, and to significantly reduce the time required for welding, compared to conventional welding methods in which welding is performed along the edge of the coupling face. |
