Vehicle bodywork and frame production process, involving building up object, dividing it into sections and fixing end sections of parts together

摘要

The production process includes the steps of: building up the object of the required initial form, e.g. one with a closed cross section, by producing a pair of end sectors on it, possibly by means of hydraulic deformation; dividing the object into first and second sectors; and firmly fixing the end sector of the first part to the end sector of the second part.
