Abstract: A welding system includes: a setting apparatus configured to move a material to be welded to a desired welding position according to a disturbance condition of the material to be welded 1; a welding robot configured to weld, according to a working condition, the material to be welded moved by the setting apparatus; an inspection apparatus configured to inspect a welding quality of the material to be welded that is welded at a current time; a storage apparatus configured to store the working condition for the current time, the disturbance condition for the current time, and the welding quality of the current time in association with one another; and a determination unit configured to change, when the welding quality of the current time stored in the storage apparatus satisfies a predetermined required quality, the corresponding disturbance condition for the current time and set the changed disturbance condition as a disturbance condition for a next time.

Abstract: A master unit includes a welding DB in which prescribed motion data associated with an object to be welded is stored, a state sensor which measures, as welding state data, a situation of welding by a robot which executes welding in a real environment according to the prescribed motion data, a simulated environment which imitates the real environment and notifies a worker of the welding state data, and a motion control unit which receives, as an input, worker motion data indicating a motion of welding by the worker from the simulated environment, operates the robot in the real environment by using the worker motion data instead of the prescribed motion data, and records, as new prescribed motion data, the input worker motion data in the welding DB.
