Abstract
Infusion joining, the major influencing parameters are speed and heat input, commonly determining joining microstructure, defects, and its effect on properties. Here we choose beam oscillation as a process parameter with a function of intermetallic compounds (IMCs) due to the introduction of churning action and bath homogenization. Beam oscillation is performed by changing its oscillation diameters, and an optimum diameter has been found to produce the lowest percentage IMCs with uniform distribution at the fusion interface than those from the non-oscillating counterpart. Also, beyond optimum diameter produces more Al-rich intermetallic, i.e., Fe4Al13 with needle and cluster/agglomerated type.
