<p>Aluminum alloy materials, due to their low density, high strength, and corrosion resistance, have been widely used in various fields. Currently, various industries place great importance on the manufacturing quality of aluminum alloy mechanical structural components, striving for lightweight designs while ensuring reliability. Since the production of certain components involves welding technology, the requirements for the welding quality of aluminum alloy parts are steadily increasing. The quality of aluminum alloy welding directly impacts the practical application of welded parts, while the welding test research and evaluation system can measure the efficiency and quality of aluminum alloy welding. This paper reviews the experimental and testing methods used in recent years for aluminum alloy welding research, points out the shortcomings and areas for improvement in the experimental and testing approaches currently used in welding research, and summarizes and proposes a more comprehensive evaluation system for aluminum alloy welding experimental testing.</p>
