Abstract: A photon energy beam delivery system has a gas delivery tube extending generally the length of the beam path, having a plurality of openings oriented generally toward the beam path. Gas is discharged through the openings, flowing proximal to the beam path, resulting in the desired gas movement within the beam path throughout a sufficient length of the beam path, thereby reducing, eliminating or minimizing degradation of the beam.

Abstract: In a system for the control of the quality of a laser cut or perforation, comprising means to focus a laser beam onto a cut or perforation zone, photodiode sensor means to detect the radiation emitted by the cut or perforation zone, and a control and processing electronic unit to process the signals emitted by said sensor means an optical filter is provided that is associated with said photodiode sensor means to select an optical band around 620 nm. The signal coming from said sensor means is acquired with a frequency comprised between 10 and 60 kHz and filtered with a band-pass filter between 7 and 16 kHz. In this way the control of the quality of the cut or perforation can be carried out on the basis of the sole signal thus processed, without the need of a comparison with the predetermined reference signal corresponding to a good quality cut or perforation.

Abstract: A configurable baffle to configure fluid flow through a nozzle. To improve the quality and accuracy of processing apparatus used in the cutting, welding, and heat treating of materials, a self-aligning nozzle includes a configurable baffle. This configurable baffle can be a metallic grid (e.g., a screen) or other type of membrane (e.g., porous, permeable, etc.). During its initial use in the processing apparatus, this configurable baffle is tailored with an energy beam, such as a laser beam or plasma jet, to create an optimal fluid flow velocity profile. When the configurable baffle deteriorates from use, it is easily replaced by another baffle or by using an in situ replacement mechanism. To ensure proper alignment between the nozzle and the energy beam, mating contoured surfaces are used among adjacent components. Threaded surfaces can also be employed to assist in achieving the proper coaxial alignment.

Abstract: A method of protecting a laser unit from dust during laser processing of a target in a processing area includes establishing an essentially ambient pressure at the processing area, and directing a longitudinal gas flow towards the processing area to establish in a first region intermediate the processing area and the laser unit, thereby effectively preventing dust from moving towards the laser unit and at the same time minimizing the forces acting on the target. A corresponding dust protection device defines a channel extending from a radiation inlet opening, facing the laser unit, to a radiation outlet opening, facing the target. A gas control unit communicates with the channel to feed gas thereto through at least one gas inlet aperture spaced from the radiation outlet opening. Simultaneously, the gas control unit removes gas from the channel through at least one gas outlet aperture adjacent to the radiation outlet opening.

Abstract: Glass tubes are fed one at a time from a supply to a station. Each of the tubes is rotated in the station about a longitudinal axis of the tube in the station and is simultaneously pressed axially against a fixed stop. A laser beam is directed at the rotating tube in the station at a location along the tube offset from the stop to melt the tube at the location and cut from the tube a section lying between the location and the stop. After cutting from the tube, the tube section is transversely displaced onto a conveyor and transported away from the station by the conveyor. Then the tube in the station is advanced axially into engagement with the stop and the steps of rotating, cutting, and so on are repeated until the tube is exhausted.

Abstract: An insulated slag collection bed for a laser-equipped machine tool. The bed substantially insulates the machine tool base from thermal damage due to the laser beam of the machine tool. Typically the laser beam in a machine tool will have significant energy density in planes below the workpiece, and in some conditions the energy density will be sufficient to damage the machine base. The present invention protects the machine base by providing a slag collection bed which serves as a shield to absorb remnant laser energy which would otherwise strike the machine base. The shield is thermally insulated from the machine base so as to protect the machine base from the temperature rise in the shield resulting from absorbing the remnant laser energy. If, over time the shield is damaged or worn, means are provided for ready replacement of both the shield and the insulation.

Abstract: A process and apparatus for continuous welding by a laser beam of guided and abutted strips or plates which lie in a plane comprises supplying a follow-up process gas to a welding location and thereafter, cooling the welding location by applying a sprayed-on coolant to an area adjacent to the welding location. The coolant comprises a mixture of water and gas, and is sprayed onto the strips or plates in the form of a flat jet. The flat jet extends towards the welding location and lies in a plane perpendicular to the plane of the strips or plates. The leading edge of the flat jet forms an acute angle with the laser beam.
