Abstract
Due to their unique qualities, such as superior corrosion resistance, formability, and a strong strength-to- weight ratio, aluminium alloys are key materials in a variety of industries. However, the majority of failures in structural parts occur as a result of a catastrophic failure, i.e., without warning, namely fatigue failure. The majority of the study has focused on using a new approach, such as pre- and post-weld heat treatment, to improve the fatigue life of structural parts. The component’s fatigue life was improved in this study by using a solution treatment followed by an age hardening. According to the findings of the experiments, the solution and ageing treated joint had a longer fatigue life than the typical in as weld state.
