摘要： In a laser beam machine head, when a filler wire and an optical axis of a laser beam are arranged coaxially, a convex roof mirror and a concave roof mirror are combined to divide the laser beam into two separate laser beams to that no laser beam is projected onto a filler wire feed pipe. Furthermore, the filler wire is fed from outside the laser beams to a condensing position via a filler wire guide in the spacing between the separate laser beams, or an electrode supported by a water flow pipe or an electrode holding pipe is brought close to the condensing position.

摘要： In a method for monitoring laser beam welding, a sequential signal representing a laser oscillating wave form is received, light of a predetermined wavelength in the light emitted from the weld zone is received, and the two signals thus received are processed to determine the minimum intensity of the light of the predetermined wavelength and thereby accurately deduce welding beam input and penetration of welding. An apparatus used in practicing the monitoring method includes a monitoring optical fiber for receiving and transmitting the light emitted from a weld being made on a workpiece, an interference filter for selectively passing light of a predetermined wavelength, and a processing device for determining an intensity of the light of the predetermined wavelength.

摘要： The known reflecting mirror for a laser beam conisting of a mirror base member and a high-reflectivity metal coating layer formed on the mirror base member for reflecting a laser beam, is improved so as to maintain a high mirror reflectivity without necessitating a cooling facility. The improvements reside in that a coating layer having a small diffusion coefficient is provided on the back surface side of the high-reflectivity metal coating layer, and/or in that at least one layer of dielectric coating layer or layers are provided on the surface of the high reflectivity metal coating layer. Also, an improved laser beam welding apparatus for an inner circumferential surface of a tube is provided by employing the aforementioned improved reflection mirror as a reflecting mirror in an optical condensing system included in a laser beam welding apparatus for an inner circumferential surface of a tube, which apparatus comprises a flexible tube including an optical fiber extended therethrough for transmitting a welding laser beam, said flexible tube being insertable into a work tube, a position detector for detecting a relative position of the flexible tube with respect to the work tube and fixing means of internally expansible type for fixing the flexible tube within the work tube, respectively provided at the front end portion of the flexible tube, a rotary cylinder rotatably supported from the flexible tube, guide support means mounted to the rotary cylinder in a relatively rotatable manner and being able to be held in contact with the inner wall surface of the work tube for holding the rotary cylinder concentrically with the work tube, rotary drive means having its output shaft disposed coaxially with said rotary cylinder for rotationally driving the rotary cylinder, an optical condensing system disposed within said rotary cylinder for leading the welding laser beam emanating from the front end of the optical fiber to the inner wall surface of the work tube in a condensed state, gas scavenging means for discharging metal vapor produced upon welding of the work tube, and gas cooling means for cooling the optical condensing system.

摘要： Control is exercised such that an arc discharge from a GMA electrode is performed after or simultaneously with start of oscillation of laser light from a laser oscillator, and oscillation of the laser light from the laser oscillator is stopped after or simultaneously with termination of the arc discharge from the GMA electrode. A coaxial laser beam machining head is configured such that the GMA electrode is disposed in a space portion between a first divisional laser beam and a second divisional laser beam, which have been formed by division by first and second reflecting mirrors, coaxially with the laser beams. Alternatively, the coaxial laser beam machining head is configured such that the GMA electrode is disposed in a space portion, which has been formed in a body of laser light by withdrawing part of the laser light outwardly with the use of first and second reflecting mirrors, coaxially with the body of the laser light.
