Method for blind rivet welding

摘要

A blind rivet assembly is inserted through aligned holes provided in a top member and bottom member. The blind rivet includes a rivet head that abuts the top member and a hollow rivet shank integral with the rivet head. A mandrel includes a mandrel stem that extends thorough the hollow rivet and a mandrel head that abuts the terminal end of the rivet shank. A tool holds the rivet head in contact with the top member and forcibly withdraws the mandrel in the direction to exit the aligned holes to thereby cause the mandrel head of axially collapse and radially expand the terminal end of the rivet shank into engagement with the bottom member to thereby attach the top member and the bottom member together. Weld current is then applied to the rivet head to thereby weld the blind rivet in place.
