Abstract:
A method for the production of a closed hollow profile for a vehicle axle including the following steps: a) provision of a board made out of a sheet of metal, wherein the board has at least a length in a longitudinal direction and at least a width in a transverse direction, b) forming of the board, creating an open profile with a channel running in a longitudinal direction of the board, c) forming the lateral surfaces of the board, creating a hollow profile with a circumference and a longitudinal gap and d) joining together the longitudinal gap.
