Abstract: Disclosed are an apparatus and system for evaluating a welding condition on the basis of three-dimensional data. An aspect of the present embodiment provides an apparatus for evaluating a welding condition, the apparatus including a communication unit configured to receive a three-dimensional image for an evaluation target from the outside, a base material recognition unit configured to recognize a base material from the three-dimensional image for the evaluation target by using a point cloud, a bead extraction unit configured to extract a welding bead welded between the base materials, a bead cross-section acquisition unit configured to acquire cross-sections at preset intervals for the extracted welding bead, and a profile analysis unit configured to analyze a profile of the welding bead for the cross-section acquired by the bead cross-section acquisition unit.
