Abstract: During melting and jointing members 2, 3 to weld the members by applying a laser beam 5 to the members while supplying a filler wire 13 to the locally heated portion of the members, welding plasma intensities are measured by sensors 8, 9 from both sides of the locally heated portion with reference to an advancing direction of welding. When the welding plasma intensities measured from both sides of the locally heated portion are largely different from each other, the relative deviation between the laser beam 5 and the filler wire 13 is large, so that a good welding may be difficult to be carried out. Based on this recognitions, the relative position between the laser beam 5 and the filler wire 13 is corrected during welding to prevent occurrence of weld inferiority, so that the occurrence of weld inferiority due to the relative deviation between the the laser beam 5 and the filler wire 13 can be effectively prevented, thereby scrapped inferior members can be decreased providing a reduction of costs of materials and an improvement of weld efficiency.

Abstract: A laser processing arrangement includes a laser oscillator which outputs a laser beam. The laser beam path is established such that the beam reflects from a flat surfaced mirror to a concave mirror and then to a second concave mirror before irradiating a work piece under processing. The arrangement further includes a temperature sensor associated with a temperature detecting means. The temperature detecting means is connected to a control unit which controls moving means connected to movable axes of a processing surface in order to move the work piece relative the laser beam. The control unit is further effective to control the laser oscillator according to a desired temperature range for processing. The temperature sensor is preferably positioned within 45.degree. of the laser beam and the angle of incidence of the laser beam is selected so as to be smaller than a brewster angle of the material of the work piece.

Abstract: A laser hardening device for forming a hardened layer on the surface of an object irradiated by a laser beam is so arranged as to emit a laser beam which is linearly polarized in the incidence plane containing the normal to the surface and the optic axis of the laser beam irradiating the surface. The device comprises a first concave mirror for condensing the laser beam the incidence plane, and a second concave mirror for condensing the laser beam in a perpendicular plane to the incidence plane, the first concave mirror being disposed closer than the second concave mirror to the laser oscillator in the path of the laser beam. Laser beam is therefore absorbed at a high absorption rate by the object, and a hardened layer is formed without coating a laser absorption agent onto the object. The incidence angle of the laser is preferably no less than 60 degrees, and by arranging that the laser beam is parallel on the irradiated surface, a uniform, hardened layer is obtained. Moreover, by blowing shield gas on the irradiated surface from a gas nozzle provided with a smoothing mechanism such as metal mesh, oxidation of the hardened layer or surface melting due to oxidation is prevented and a more desirable hardened surface is obtained.
