Abstract
During manufacture of certain hollow profiles suitable for use in car body construction the welded profiles are subjected to a further deformation process, namely hydroforming. At present the corresponding welding machines are charged manually. The invention relates to a method and a device for transferring hollow-profile blanks, characterized in that during transfer the positioned fusion faces of the blanks are pressed against each other at least in the area of the weld.
