PROBLEM TO BE SOLVED: To provide a welding robot device of a large frame structure which can perform the permanent welding of intersection parts of the large frame structure, in which longitudinals and transverses are intersected with each other on a panel, is less in restriction of welding parts capable of performing the permanent welding, is almost needless of manual welding by human hands, can be more downsized as the entire device in comparison with a conventional multi-robot welding apparatus using a large gantry structure, and can eliminate any complicated control system. SOLUTION: The welding robot device of the large frame structure has a robot frame 10 having a horizontal supporting frame base 12 fixed to the large frame structure across an objective welding area 4 and located on an upper part of the objective area while the objective welding area 4 is a space of frames of a rectangular shape surrounded by a pair of longitudinals 2 and one transverse or a plurality of transverses 3, and a welding robot 20 which is mounted on a lower side of the horizontal supporting frame base 12 and capable of executing the welding by performing the numerical control of a welding head in a three-dimensional manner over the entire area within the frame of the rectangular shape (the objective welding area 4).
