The experiment of digital imaging test of aluminum alloy friction stir welding joint was carried out using eddy current array testing system. Firstly, the testing technology was carried out to determine the appropriate parameters. The friction stir welding products were tested by using eddy current array and dye-penetrant testing method. Through the comparison experiments, it is found that the testing results are similar and the imaging results are clear and reliable. Research results showed that eddy current array testing technology is expected to be used for the surface and subsurface testing of friction stir welding of aluminum alloy and other materials to realize fast, accurate and digital imaging testing.
