INSTALLATION FOR WORKING A ZONE OF A TUBE BY MEANS OF A LASER BEAM AND APPLICATION TO TUBES OF A PIPING ON A BARGE LAYING AT SEA OR RECOVERING FROM THIS PIPING.

摘要

A laser device (L, G, T) is placed on a frame (B) rotatably supporting the holder of a working head (T) of the device, and the device is housed along with the frame in a container (c) attached to a tube extending therethrough during the working process. The mass of the container and its contents considerably reduces the transmission of stress from the tube to the working head.
