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.

A substrate processing method is provided. The substrate processing method includes placing a substrate storage container storing a substrate on a load port; automatically determining a type of the substrate stored in the placed substrate storage container; by referring to a storage unit that stores a parameter data set related to a transport condition for each substrate type, controlling transport of the substrate stored in the substrate storage container based on the parameter data set corresponding to the automatically determined type of the substrate to process the substrate, and, after automatically determining the type of the substrate, and before transporting the substrate stored in the substrate storage container, performing mapping based on conditions set in the parameter data set to detect an abnormality of the substrate stored in the substrate storage container.
