Al/Fe dissimilar metals welding has the advantages of lightweight structure and good comprehensive performance

which has a wide application prospect in aerospace

nuclear power energy

automobile

electronic and electrical appliances and other industries. However

due to the difference of physical properties

there are still many problems in joining methods and processes of Al/Fe dissimilar metals. Electromagnetic pulse welding

a solid-state welding technology

which can effectively overcome the welding problems caused by the different properties of dissimilar metals

is widely used in welding of dissimilar metals such as Al/Fe. This paper briefly analyzes the problems existing in Al/Fe dissimilar metal welding

and the welding principle

process

characteristics of electromagnetic pulse welding technology. Then summarizes and analyzes the new progress of electromagnetic pulse welding technology from the aspects of process research

equipment optimization

joint performance

interface morphology and bonding mechanism

numerical simulation

and the combination of various welding methods

and puts forward corresponding suggestions for the future technological development.
