Features of the design and capabilities of the smartphone-based eddy current flaw detector with the EddySmart software application are presented, which in the future can provide remote control with wireless transmission of inspection results via mobile communication channels for further analysis and storage. The perspectives of application of eddy current probes of double differentiation type for inspection of welded joints of structures made of aluminum alloys are considered. The characteristics and results of studies of low-frequency double differentiation eddy current probes of MDF 0801 and MDF 1001M type with operational diameters of 8 and 10 mm, respectively, developed for detection of the defects in aluminum alloy welded joints are presented. It is shown that to detect defects of different type in aluminum alloy welded joints at a greater depth, preference should be given to the improved eddy current probe of MDF 1001M type with an operational diameter of 10 mm, which provides a higher level of signals and better noise resistance. 16 Ref., 2 Tabl., 7 Fig.
