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 body are type of 5XXX aluminum sheets.

适用于汽车车身的铝板分析与检验：超声波检测、信号处理、仿真

摘要

今天，汽车行业发生了许多变化。用于汽车车身的所有铝板都必须具有良好的可焊性。在本文中，我们将测试 6 种 5XXX 和 6XXX 铝板的点焊。经过对所有板材的焊接测试，这些板材被选为最适合汽车车身的板材。该测试通过超声波检查。从超声波测试中获得的信号没有准确的结果来更好地确定纸张。为此，对获得的信号进行信号处理以检测纸​​张缺陷。通过模拟这些板材，可以在实验测试和模拟之间进行比较，从而对所选板材做出最佳决策。这些表的状态图已经过审核，很容易在最短的时间内选出经过测试的表。一般而言，调查结果表明，最适合汽车车身的板材是 5XXX 型铝板。
