Abstract

Welding aluminum alloys is highly prone to porosity formation during the solidification phase of the weld metal, resulting directly in diminished, mechanical strength properties of the weld. This research, therefore, uses a systematic literature review method to identify the previous studies related to vibration welding. The purpose was to determine the effect of vibration welding on improving the mechanical properties of aluminum alloys. The findings showed that vibration welding could break the secondary dendritic arm and form new solid-phase nuclei during the solidification process. Meanwhile, forming new solid-phase nuclei usually leads to smaller and finer grain size. This method was, therefore, able to refine the grain size from 200 μm to 115 μm and increase the tensile strength from 287 MPa to 295 MPa.
