Title:

LASER TYPE PIPE PROCESSING APPARATUS

Document Type and Number:

Japanese Patent JPS58148089

Kind Code:

A

Abstract:

A laser pipe welder/cutter for use where a pipe to be welded or cut cannot be rotated, consisting of a focusing head mounted on a carriage which runs on a track surrounding a hole in a base plate through which a section of pipe to be operated upon can project. The focusing head is arranged to maintain the laser beam at normal incidence to the pipe as it traverses around the pipe and is linked to a laser source via a flexible laser beam guide which consists of at least two rigid sections joined by optical elbow joints which permit motion about two mutually perpendicular axes, the lengths of the rigid sections being such that the laser focusing head can traverse more than a full circle around the pipe without the rigid sections of the laser beam guide coming into contact with the pipe.
