Effect of RSW Lap Joint Types of Aluminium and Austenitic Stainless Steel Strength
Journal Title: Machine Design - Year 2018, Vol 10, Issue 3
Abstract
The lightweight design finds its application in various areas, although its application is most common in the automotive and aerospace industries. The most commonly light construction is achieved by combining different materials into one structure, among which steel and aluminum are the most combined. The precondition for achieving this multi-material structure is the application of efficient and inexpensive bonding technologies of various materials, such as RSW (Resistance spot welding) process. Due to material differences, welding of aluminum and steel alloy encounters many problems, primarily due to differences in thermal and physical properties and due to the appearance of the fragile Fe-Al intermetallic compound (IMC).This intermetallic compound directly affects the load of the RSW steel and aluminum compound which will be shown in this paper. The thicker IMC provides less load and the thickness itself can be controlled depending on the type of aluminum and steel joining, i.e. whether the steel is screwed over aluminum or aluminum over steel.
