Information prompting method

The information presentation method is an identifier information presentation method managed by a welding system, and selects information of an identifier of a workpiece to be welded produced by a welding process using a plurality of source workpieces from among information of identifiers assigned to each of the plurality of source workpieces. An alarm is notified if an identification symbol corresponding to an unselected identifier is read by a reading device from among identification symbols of information capable of reading an identifier configured for each of a plurality of source workpieces, and if an identification symbol corresponding to a selected identifier is read by the reading device, the alarm is notified if the identification symbol corresponding to the selected identifier is read by the reading device. And if so, prompting the information of the selected identifier. 信息提示方法是通过焊接系统进行管理的标识符的信息提示方法，从对多个源工件中的每一个源工件赋予的标识符的信息当中选择通过使用了多个源工件的焊接工序生产的被焊接工件的标识符的信息，在选择后，若从能读取对多个源工件中的每一个源工件配置的标识符的信息的识别符号当中通过
