Weld bead appearance inspection device, weld bead appearance inspection method, program, and weld bead appearance inspection system

The weld bead appearance inspection device is provided with: an input unit that inputs input data relating to a weld bead of a workpiece produced by welding; a first determination unit that performs a first inspection determination related to the shape of the weld bead based on a comparison of the input data and the main data; k second determination units having built-in k types of artificial intelligence, where k is an integer of 1 or more, and performing a second inspection determination related to a welding defect in a weld bead based on processing of the input data by the k types of artificial intelligence; and a comprehensive determination unit that outputs a result of appearance inspection of the weld bead to an output device based on determination results from the first determination unit and the k second determination units. 焊道外观检查装置设置有：输入单元，将与通过焊接生产的工件的焊道相关的输入数据作为输入；第一确定单元，基于输入数据与主数据的比较来执行与焊道的形状相关的第一检查确定；k个第二确定单元，内置有k种人工智能，并且基于k种人工智能对输入数据的处理来执行与焊道中的焊接缺陷相关的第二检查确定，其中k为1或更大的整数；以及综合确定单元，基于来自第一确定单元和k个第二确定
