WELD LINE DATA GENERATION DEVICE, WELDING SYSTEM, WELD LINE DATA GENERATION METHOD, AND PROGRAM

This weld line data generation device generates weld line data specifying a part to be welded by a welding robot, the device having: a recording unit in which feasibility information indicating whether welding by the welding robot is feasible is recorded for each combination of member configuration names; an extraction unit that extracts a combination of two or more adjacent members from three-dimensional data of a structural body which is manufactured using welding; and a generation unit that, if a combination of configuration names which corresponds to the extracted combination of two or more members is weldable, generates weld line data specifying a part to be welded between the two or more members that correspond to the combination. 一种焊接线数据生成装置，其生成用于特定由焊接机器人焊接的部位的焊接线数据，其具有：记录部，其记录按照构件的配置名的组合表示可否由所述焊接机器人进行焊接的可否信息；提取部，其从通过焊接所制造的结构体的三维数据中，提取相邻2个以上的构件的组合；生成部，如果与被提取的2个以上的构件的组合对应的配置名的组合为可焊接时，其生成对在组合所对应的2个以上的构件间进行焊接的部分进行特定的焊接线数据。
