摘要： An information presentation method is an information presentation method of an identifier managed by a welding system. The information presentation method includes: selecting, from information on identifiers assigned to a plurality of original workpieces, information on an identifier of a welded workpiece to be produced by a welding process using the plurality of original workpieces; and after the selecting, outputting an alert in a case in which, among identification signs on which information on identifiers arranged in the plurality of original workpieces are readable, an identification sign corresponding to an identifier that has not been selected is read by a reading device, and presenting the information on the identifier that has been selected in a case in which an identification sign corresponding to the identifier that has been selected is read by the reading device.

摘要： The repair welding system includes an inspection device and a welding device. The inspection device determines whether there is a defective portion in a welded portion. In a case that there is the defective portion in the welded portion, the inspection device extracts at least defect type information of the defective portion and inspection coordinate system defective portion position information, converts the inspection coordinate system defective portion position information into position information corresponding to a coordinate system of the welding robot and generates welding coordinate system defective portion position information, and transmits the defect type information and the welding coordinate system defective portion position information to the welding device. The welding device instructs execution of a repair welding on the defective portion based on the defect type information and the welding coordinate system defective portion position information.

摘要： A bead appearance inspection device includes an acquisition unit that acquires input data related to a welding bead, a storage unit that stores a first determination standard and a second determination standard used for an inspection of a defect of the welding bead, a first determination unit that executes a first inspection determination on the welding bead, and k second determination units, where k is an integer of 1 or more, that execute a second inspection determination on the welding bead. An appearance inspection result of the welding bead is created and output by using a determination result indicating whether a first inspection result acquired by the first inspection determination satisfies the first determination standard and a determination result indicating whether a second inspection result satisfies the second determination standard.

摘要： 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.

摘要： The control unit executes: a first execution step of executing a processing program to set a target value to a value defined by a processing program and performing feedback control on a driving current of a laser oscillator; a detection step of detecting an output fluctuation during execution of the first execution step; a specification step of specifying a physical quantity for which a measured value within a predetermined monitoring time before an occurrence timing of the output fluctuation does not satisfy a predetermined condition as an abnormal physical quantity from a plurality of physical quantities measured during execution of the first execution step; and a program update step of detecting appearance of a predetermined feature in an abnormal physical quantity as a fluctuation factor during execution of a post-update processing program, and updating the processing program to correct the driving current to reduce a difference between the laser output power and the target value compared with when the output fluctuation occurs in the first execution step after detection of the fluctuation factor.

摘要： A repair welding inspection device includes a memory that stores instructions and a processor that executes the instructions. The instructions cause the processor to perform acquiring a second threshold, which is different from a first threshold which is a determination threshold for inspection of welding performed before performing repair welding, and the second threshold being a determination threshold for inspection of the repair welding, and performing inspection after the repair welding by using the second threshold.
