Abstract

PURPOSE: To monitor the interior of weld zone from outside of pipe, by inserting a guide pipe from the send-out side of metal tape, and providing a mirror or fiber scope inside.
CONSTITUTION: A metal tape 2 let off from a send-out device 1 is formed in a circular section, with both ends joined together, by a forming die 3, and the butt ends are welded by a welding machine 5, and a pipe 4 is produced. Inside the pipe 4, a guide pipe 6 is inserted from the send-out device 1 side to the position of the welding machine 5. In the guide pipe 6 are disposed a reflecting mirror 8 to show the inside of the weld zone and a fiber scope 9 to transmit the image of the reflecting mirror 8 up to a display device 10. Thus, the state of the interior of the weld zone may be reproduced in the display device 10 and monitored. By introducing inert gas into the pipe 4 from the guide pipe 6, the oxidation of the weld zone may be prevented.
