Semi-finished products for hydroforming processes are commonly tubes,extruded profiles,or double blanks.An interesting alternative is the use of partially cladded double blanks which can be manufactured in a continuous rolling proeess using local separating layers.Partially cladded double blanks feature laminarily joined areas,e.g.in the flange region,and uncladded areas which can be bulged to hollow bodies.The present paper shows the basic fundamentals of partial roll-bonded cladding of steels arid hydroforming of partially cladded double blanks.The potentials of the process chain "partial cladding-hydroforming" are shown by manufacturing a heat exchanger and a roof rail.
