Abstract
Provided is a welding management system that appropriately manages welding. The welding management system (100) includes a plurality of local magnetic sensors (10a to 10f) provided around a target joining position (K) and a correction magnetic sensor (20) curved to surround the target joining position (K). A data processing unit (30) generates information of a joining state of the target joining position (K) based on a difference between a detection value of each of the plurality of the local magnetic sensors (10a to 10f) and a detection value of the correction magnetic sensor (20).
Claims8
A welding management system comprising:
- a magnetic detection unit that detects magnetism generated around a target joining position accompanying with energization to a member to be welded when the member to be welded is welded by heat generated accompanying with the energization;
- a data processing unit that processes a detection value of the magnetic detection unit,
- wherein the magnetic detection unit includes:
- a plurality of first magnetic detection units provided around the target joining position;
- and
- a second magnetic detection unit curved to surround the target joining position, and
- wherein the data processing unit generates information of a joining state of the target joining position based on a difference between each of detection values of the plurality of the first magnetic detection units and a detection value of the second magnetic detection unit;
- and
- a notification unit that notifies of the information generated by the data processing unit,
- wherein, when defective welding occurs in the target joining position, the notification unit displays one of the first magnetic detection units that corresponds to a position where the defective welding occurs and an other one of the first magnetic detection units in a differentiated manner.
