摘要： PURPOSE:To control an external device quickly by providing a monitor monitoring the presence of a trigger inputted externally and switching automatically an internal clock function and external clock function to the generator. CONSTITUTION:When a signal (external trigger) extracted from a pin hole 2 at its specific location during a rotating motion is given to a pulse generator 4, an external clock function is immediately selected, and a laser device 5 is stimulated based on a signal resulting from the extracted signal with a predetermined delay time added thereto. That is, when the pin hole 2 is rotated at a period of 40ms, it is supposed that the signal representing the location of the pin hole 2 is generated at 0.5ms this side from the measurement midpoint and the time required for the laser pulse rising with an external signal is 0.3ms. In order to measure various beam variables at a timewise position by a Tdms from the head of the laser pulse, a time delay of (40+0.5-0.3-Td)ms is added to the signal extracted from a rotation motion of the pin hole and the resulting signal is used to stimulate the device 5.

摘要： PURPOSE:To provide a method by which a metallic material is thermally worked by a pulse YAG laser under a welding condition suitable for the material quality and the kind of thermal working (welding, cutting, surface reforming, etc.). CONSTITUTION:When a metallic material is thermally worked by using the pulse YAG laser based on a relation of the proper length of the pulse in compliance with the material and the kind of thermal working obtained by directly measuring the beam strength distribution applied on the working point and the average power density. The thermal working is carried out in two ways. In one way, the beam strength distribution applied on the working point is preliminarily directly measured and the working is carried out using a welding condition obtained by arranging the relation of an adeproper length of pulse in comforming to the material and the kind of thermal working and the average power density. In another way, the beam strength distribution applied on the working point is directly measured and the working is carried out confirming that the average power density conforming to the material and the kind of thermal working is obtained.

CONSTITUTION:As for a structural member having a weld joint between ferrous sintered materials, ferrous sintering material and steel, cast steel/cast iron and medium/high carbon steel, the balance in the following is required, (1) a hardness Hv of weld metal is in the range of 100-350, also, a max. hardness Hv of the welding heat affected zone of ferrous sintering material is in the range of 100-450. (2) a max. hardness Hv of the welding heat affected zone of ferrous sintering material is in the range of above 450 and less than 600, also, an average hardness Hv of weld metal is in the range of 100-350. (3) An average hardness Hv of weld metal is in the range of above 350 and less than 550, also, a max. hardness of the welding heat affected zone of ferrous sintering material side is in the range of 11-450. As a result, as a tensile property, the weld joint having the strength equivalent to the base metal of lower strength side is obtained.

摘要： PURPOSE:To allow highly accurate direct measurement of beam intensity distribution by idling a laser unit with a preliminary exciting pulse while moving a detecting section at a constant period and then oscillating a pulse laser with a signal synchronized with the constant period at the detecting section with a predetermined time lag. CONSTITUTION:A measuring instrument 1 equipped with a pin hole 2 rotating at high speed is connected with a laser beam analyzing system 3 equipped with a computor. A pulse generator 4 imparts a predetermined time lag to a signal synchronized with the rotational period of the pin hole. The pulse generator 4 delivers a predetermined pulse signal to a laser unit (beam generating/controlling unit) 5. The function for idling the laser unit 5 is provided for the signal delivered from the pulse generator 4 or for the laser unit 5 itself. This method allows highly accurate direct measurement of the beam intensity distribution of pulse laser.

摘要： PURPOSE:To enable stable uniform laser welding by feeding flows of gas spouted from plural nozzles and converged on a focus under acceleration so that the focus is positioned within a plume generation region. CONSTITUTION:Plume is generated from the surface of a body 3 during welding or surface reformation with laser beams emitted from a laser oscillator 1 and passed through a torch 2 as a heat source. In order to remove the plume, flows of gas spouted from the plural nozzles of a gas feeder 6 and converged on a focus under acceleration are fed so that the focus is positioned within the plume generation region and the gas mixed with the generated plume is removed with a sucker. The scattering of the laser beams can be prevented.
