Abstract

Health monitoring of structural joints is a major concern of the engineering community. Among joining techniques, spot- welding play a major role. Spot welding is the traditional method of assembly for steel-based automotive structures, while spot-welding of aluminum is being considered for future vehicular structures. Though spot welding of steel is well researched and understood, the spot-welding of aluminum still poses a considerable challenge. The durability and health monitoring of aluminum spot-welded joint is of major importance. The present paper addresses the use of electro- mechanical method and piezoelectric active sensors for health monitoring spot-welded structural joints.
