Zusammenfassung: | Disclosed is a method for forming a vehicle body member. The method for forming a vehicle body member includes: a pipe-forming process of forming a steel pipe by welding a steel plate coil; a non-circular pipe forming process of firstly preforming the steel pipe formed in the pipe-forming step so as to have a cross section having a predetermined shape; a bending process of bending and secondly preforming the steel pipe firstly preformed in the non-circular pipe forming process; and a hot stamping process of heating the secondly preformed steel pipe, inserting the heated steel pipe into a mold to form the same in a desired shape, and then, cooling the heated steel pipe to manufacture the vehicle body member, thereby easily forming the vehicle body member having high rigidity.
