Abstract: A welding control device includes an actual position determination part configured to determine an actual position of the position control target on the basis of a weld characteristic amount detected from a captured image captured so as to include at least the position control target, the welding characteristic amount including at least one of a wire position of the weld wire or an electrode position of the electrode; a target position determination part configured to determine a target position being a target of the actual position corresponding to a weld condition for welding the weld target; and a position control part configured to execute a position control of the position control target to bring the actual position to the target position.

Abstract: A welding control device configured to control a position control object which includes at least one of a welding wire used to weld a welding object or an electrode for melting the welding wire includes a first decision unit for deciding an actual position of the position control object based on a welding feature amount detected from an image which is shot to include at least the position control object, a second decision unit for deciding a target position which is a target of the actual position according to an input condition based on the input condition which includes at least one of attitude information of the electrode when the welding object is welded or shape information of the welding object, and a control unit for performing position control of the position control object so that the actual position becomes the target position.
