Abstract
Joints combining dissimilar metals and alloys are essential parts of domestic devices and heat-exchange systems. One of the greatest challenges is to develop and implement fast and cost-effective industrial procedures to join aluminium with copper, titanium, or stainless steel. Regardless of the process conditions, such exotic metal combinations cannot be fusion welded autogenously because of the formation of highly brittle microstructures. Of all “cold-joining” processes, electromagnetic welding may offer the utmost potential for fabricating bimetallic components. The process is straightforward and mechanistically comparable to explosive bonding, except that it safely uses intense magnetic fields to collide two axis-symmetrical parts into each other. In this paper, the microstructures at interfaces of electromagnetic welds between aluminium and other metals or alloys are discussed. By carefully selecting the process conditions, microstructures and properties of weld joints (mechanical, electrical, etc.) can be controlled. Mechanical interlocking as well as thin and discontinuous intermetallic phases (all resulting from localized melting) will control the final properties of electromagnetic welds between dissimilar materials.
