Abstract:
A hollow component made of thin sheet metal members is described, along with a method of manufacturing such hollow component. The method involves applying a flow drilling process on one sheet metal member of a pair of sheet metal members having a gap G between them to form a first collar part. A flow drilling process is applied on the other sheet metal member of the pair to form a second collar part as well as to cause an inner tip of the second collar part to fuse with an inner tip of the first collar part. A cylindrical connection member is formed to strengthen a flat sheet metal members.
