Title: Analysis and examination of aluminum sheets suitable for automotion body: Ultrasonic testing, signal processing, simulation

Abstract

There are many changes in the automotive industry, today. All aluminum sheets used in the automotive body must have good weldability. In this article, we will test the spot welding on 6 types of 5XXX and 6XXX aluminum sheets. These sheets have been selected as the best sheet suitable for the automotive body after welding test on all sheets. This test was examined by ultrasound. The signals obtained from the ultrasound wave test do not have accurate results for better sheet determination. For this purpose, signal processing was performed on the obtained signals in order to detect sheet defect. By simulating these sheets, a comparison is made between the experimental test and the simulation, which can be used to make the best decision about the chosen sheets. The status charts of these sheets have been reviewed and it is easy to select the sheets that have been tested in the shortest time. Generally, findings indicated that the best suitable sheets in automotive bodyare type of 5XXX aluminum sheets.
