WIPO Patent Application WO/2019/064654

Kind Code:

A1

Abstract:

Provided is a weld management system for appropriately managing welding. A weld management system (100) comprises: a plurality of localized magnetic sensors (10a to 10f) disposed at the periphery of a location (K) being joined; and a correction magnetic sensor (20) which is bent in such a way as to surround the location (K) being joined. Furthermore, a data processing means (30) generates information relating to a joining state of the location (K) being joined, on the basis of the difference between detected values from each of the plurality of localized magnetic sensors (10a to 10f) and a detected value from the correction magnetic sensor (20).
