The invention discloses an automobile threshold stiffening beam which is an integrally-formed part obtained by rolling a steel plate with selected strength and laser welding with distributed point positions, and the cross section of the threshold stiffening beam in the direction perpendicular to the length direction comprises four cavities which are closed respectively. The partially-overlapped side edges of the cavities in the height direction of the threshold stiffening beam are continuously spliced to form a reinforced supporting plate, and the number of the cavities arranged on the outer side and the number of the cavities arranged on the inner side which are separated by the reinforced supporting plate are equal, and the cavities are distributed in a staggered mode. The automobile doorsill stiffening beam passes through a continuous automatic production line and is sequentially subjected to punching, roll forming, local laser welding and bending cutting to obtain independent finished ...
