Abstract
A welding method is executed by a welding system in which identification signs are arranged on a plurality of original workpieces to be used in a welding process, respectively. On the identification signs, identifiers of the respective original workpieces are readable. The welding method includes executing the welding process such that a part or an entire of the identification signs is hidden in a joint surface on which the plurality of original workpieces are joined in the welding process.
Claims11
A welding method to be executed by a welding system,
- wherein identification signs are arranged on a plurality of original workpieces to be used in a welding process, respectively, the identification signs on which identifiers of the respective original workpieces are readable,
- the welding method comprising:
- executing the welding process such that a part or an entirety of an identification sign of one of the plurality of original workpieces is hidden by another of the plurality of original workpieces that are joined in the welding process,
- wherein the identifiers of the respective original workpieces distinguish the original workpieces from each other.
An identification sign assignment device configured to assign identification signs to a plurality of original workpieces to be used in a welding process executed by a welding system, respectively, the identification sign assignment device comprising:
- a communication unit configured to acquire welding information comprising information on identifiers of the respective original workpieces and information on an identifier that is not selected as an identifier of a welded workpiece to be produced in the welding process among the identifiers of the plurality of original workpieces;
- and
- a processor configured to control a laser oscillator to mark the plurality of original workpieces with the identification signs based on the acquired welding information, the identification signs on which information on the identifiers corresponding to the respective original workpieces are readable,
- wherein the identification signs are marked on the plurality of original workpieces such that a part or an entirety of an identification sign of one of the plurality of original workpieces having the identifier that is not selected as the identifier of the welded workpiece is hidden by another of the plurality of original workpieces that are joined by the welding process, and
- wherein the identifiers of the respective original workpieces distinguish the original workpieces from each other.
A weldment produced by execution of a welding process by a welding system, the weldment comprising:
- a plurality of original workpieces having identification signs arranged thereon, the identification signs on which identifiers of the respective original workpieces are readable,
- wherein the plurality of original workpieces are welded together by a welding process using a welder such that a part or an entirety of an identification sign of one of the plurality of original workpieces is hidden by another of the plurality of original workpieces, and
- wherein the identifiers of the respective original workpieces distinguish the original workpieces from each other.
