An identifier management method is executed by a welding system. The identifier management method includes: acquiring information on identifiers of a plurality of original workpieces; selecting, according to a predetermined rule, any one of the identifiers of the plurality of original workpieces to be adopted based on completion of execution of a welding process using the plurality of original workpieces by the welding system; and setting the any one of identifiers of the plurality of original workpieces, which has been selected, as an identifier of the welded workpiece generated in the welding process.

An identifier management method is executed by a welding system. The identifier management method includes: acquiring information on identifiers of a plurality of original workpieces; randomly selecting any one of the identifiers of the plurality of original workpieces to be adopted based on completion of execution of a welding process using the plurality of original workpieces by the welding system; and setting the any one of identifiers of the plurality of original workpieces, which has been selected, as an identifier of the welded workpiece generated in the welding process.

An identifier output method is executed by a welding system. The identifier output method includes: acquiring information on identifiers of a plurality of original workpieces to which identification signs are assigned, respectively, the identification signs being assigned such that information on the identifiers are readable; selecting, from the identifiers of the plurality of original workpieces according to a predetermined rule, an identifier to be set for a welded workpiece to be produced by a welding process using the plurality of original workpieces; and after the selecting, in a case in which any identification sign among the identification signs assigned to the plurality of original workpieces is read by the reading device, outputting, as an identifier of the welded workpiece, the information on the identifier that has been selected to the reading device.

The present invention is a weld line-detecting method when fillet welding by an industrial robot including a welding torch is taught. The welding torch on which an angle sensor having a contactor is attached is moved toward a welding object, angle information obtained when the contactor is in contact with the welding object is transmitted to the industrial robot, and the industrial robot moves the welding torch based on the angle information so that the angle of the contactor becomes zero. These operations are repeated, and the welding torch is moved toward a fillet part along the surface of the welding object. When the contactor arrives at the fillet part, a signal indicating that the contactor is pressed in the axial direction of the contactor is transmitted to the industrial robot. The industrial robot detects that the contactor arrives at the position to be welded on the weld line.
