# Welding method, identification sign assignment device, and weldment

## 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.
