摘要： A system and method for monitoring the molten state for enabling a molten state, butting state, or other state of electric-resistance-welded pipe on-line more accurately than in the past are provided. That is, a mirror 23 provided at a front end side inside a container 21 receives light emitted by the welded parts 5 of the tube-shaped steel strip 1 themselves through heat resistant glass 22 from the side direction and reflects the image of the welded parts 5 of the tube-shaped steel strip 1 in the direction of a relay lens 24 provided at a base end side of a relay lens unit 13. The relay lenses 24 relay the image of the welded parts 5 of the tube-shaped steel strip 1 to a conversion lens 12, then the conversion lens 12 forms that image on the imaging area of a CCD camera 11. Therefore, it is possible to capture the welded parts 5 of the tube-shaped steel strip 1 from the side direction by a resolution in accordance with the resolution of the CCD camera 11 and possible to obtain information of the welded parts 5 of the tube-shaped steel strip 1 more accurately than in the past and on-line.

The relay lenses relay the image to a conversion lens, which forms the image on the imaging area of a CCD camera. Therefore, it is possible to capture the welded parts from the side direction by a resolution in accordance with the resolution of the CCD camera and possible to obtain information of the welded parts more accurately than in the past and on-line.
