Joining end-to-end tubing of dissimilar materials by forming

摘要

This paper presents a plastic deformation process for joining two tubes made from dissimilar materials by their ends. The process consists of two elementary tube forming operations that are carried out in a single stroke; expansion to produce two adjacent counterfacing surfaces and compression beading to lock the tubes together, and has potential to replace existing solutions based on the utilization of fastened, crimped, welded, brazed or adhesive bonded joints.
