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.

A weldment manufacturing method includes drilling that forms a hole on a workpiece, feeding a filler material to the hole and putting the filler material on a bottom of the hole, and melting the filler material by emitting a laser beam to the hole while scanning with the laser beam, so as to fill the hole with the melted filler material. By repeating the feeding and the melting, a weld repairing portion filling the hole is formed.

A welding camera () is constructed with: a lens () for focusing incident light; an optical filter () that comprises a neutral density filter for reducing the amount of the incident light, an ultraviolet cut filter for cutting ultraviolet rays, and a green band-pass filter for transmitting green light; a CMOS imaging unit () that has a wide dynamic range function, and detects the light which has passed the optical filter (); a video signal processing unit () that has an automatic gain control function and a digital signal processor, and outputs an image signal, which covers a range of a low-intensity dark part to high-intensity arc light, to a display unit on the basis of an electric signal that is input from the CMOS imaging unit ().
