Abstract

PURPOSE:To produce a titled pipe without causing thermal damage in plastic coated wire-like bodies by forming a metallic tape into a pipe while containing said wire-like bodies therein and welding the seam of the tape by a laser. CONSTITUTION:A metallic tape 1 attached with plastic-coated wire-like bodies 2 longitudinally is formed to a pipe in such a way as to contain the bodies 2 therein. The seam 5 of the tape 1 formed into the pipe is welded successively by a laser in the following manner to produce a metallic pipe 6: For example, the laser light 9 from a laser oscillator 8 is reflected by a reflection mirror 10 to a focusing mirror 11, by which it is focused to a welding point 12, whereby the seam 5 is melted and welded. In order to focus the laser at the point 12 at this time, the points A, B before and behind the point 12 are observed with television cameras 13, 13' and the signals from the cameras 13, 13' are processed with a microcomputer 14 or the like, after which they are transmitted to a driving device 15 to control the direction of the mirror 11.
