Abstract

PURPOSE: To protect the detector and extend the service life thereof, by completely covering the weld line detector to shut off spatter and radiation heat from the arc spot while welding, when welding metal plates or the like.
CONSTITUTION: A weld line detector 3 is covered with a fixed cover 12 and rotating covers 14, 14'. The rotating cover 14 can be returned to the original position by means of a spring 15. The fixed cover 12 secures the detector 3 to a support member 2 through a support plate 9. Since the rotating covers 14 and 14' are positioned with a level difference, contact with the detector 3 may be prevented. When a detector support plate 5 is lowered by a lifting device 2 of the detector 3, the lower end part pushes open the rotating cover 14 to start rotating motion. When lowering further, the rotating cover 14 opens to 90°, and the detector 3 is projected out of this opening, so that the weld line may be detected. After detection, the detector 3 is raised, and the rotating cover 14 closes by the force of spring 15, so that the detector 3 is protected from the welding spatter and heat.
