| Abstract Scope |
Linear friction welding (LFW) is a solid-state joining process with potential for welding dissimilar materials, offering advantages such as reduced heat-affected zones and enhanced joint strength. Aluminum-to-steel joining finds applications in aerospace, maritime, and automotive where tailored material properties are needed. Directly joining aluminum to steel is challenging due to the formation of intermetallic compounds at the joint interface during fusion joining processes; LFW may overcome this challenge.
While LFW simulation has been studied, most studies focus on welding of similar materials. Modelling of dissimilar materials poses unique challenges as workpieces cannot be modeled as rigid bodies, detailed study of friction coefficient is needed, and material properties and thermomechanical interactions must be accurately replicated. This paper presents a comprehensive numerical simulation study of the LFW process applied to dissimilar materials, namely Al F357 and SS304. Insights will be provided into digital development of a processing window with experimental validation. |
