摘要： A fiber laser beam processing apparatus is configured by a fiber laser oscillator (10), a laser power source unit (12), a laser beam injecting unit (14), a fiber transmission system (16), a laser beam irradiating unit (18), and a processing table (20). A portion of a fiber laser beam oscillated and output by the fiber laser oscillator (10) is received by a photo diode (42) for monitoring the power through a beam splitter (40). An output signal of the photo diode (42) is sent to the laser power source unit (12). The power source unit (12) receives the output signal of the photo diode as a feedback signal and controls a driving current or an excitation current to be supplied to a laser diode (30) of a pumping unit (24) such that the laser output of the fiber laser beam equals a set value.

摘要： A laser weld monitoring system capable of assessing a weld quality of welding using a pulsed laser is provided. The system includes at least one sensor capable of capturing a weld characteristic of welding using said pulsed laser. The weld characteristic has multiple attributes. The system also includes data acquisition and processing equipment adapted for storing and analyzing the weld characteristic. A user first performs multiple welds to capture at least one weld characteristic for each weld. The user then determines the weld quality of each weld, and runs at least one of a library of algorithms associated with the attributes on said at least one weld characteristic for each weld to generate a single value output for the associated attribute. The user selects an attribute indicative of the weld quality by correlating the single value outputs of said at least one algorithm with the weld qualities of the welds.

摘要： It is an object of the present invention to provide a laser welding process and a laser welding system, wherein the welding of a fine area can be achieved, for example, with a welding nugget diameter equal to or smaller than 100 µm and a penetration depth equal to or larger than 200 µm, and a reduction in size of the system can be achieved.
To this end, a laser welding process according to the present invention comprises the steps of allowing a laser beam outputted from a laser beam generating means 1 to enter into an optical fiber 10 through a light-introducing optical unit 9, and applying the laser beam exiting from the optical fiber 10 to a weld zone through a light-delivering optical unit 11. The laser welding process is characterized in that the optical fiber 10 has a core diameter set to be within 100 µm; an NA value for entrance of light into the optical fiber 10 is set to be equal to or smaller than 0.05, an NA value for exiting of light from the optical fiber 10 is set to be equal to or smaller than 0.1; and an energy of a one-pulse laser beam applied from the light-delivering optical unit 11 is set at a value equal to or smaller than 1 joule (J).

摘要： A resistance welding power supply apparatus comprises a large-capacitance capacitor (10) for storing resistance welding energy in the form of electric charges, a charging circuit (12) for charging the capacitor (10) up to a predetermined voltage, a switching element Q (TR 1 to TR n ) electrically connected between the capacitor (10) and one electrode of a pair of welding electrodes (14) and (16), and a control unit (20) for allowing an switching operation of the switching element Q via a drive circuit (18) during the supply of welding current to thereby provide a control of a welding current I. If the welding current I is less than a set current value at a point of time on the leading edge of a clock CK, then the control unit (20) holds a control pulse CS for the switching element Q active or high from that point of time till the time when the welding current I exceeds the set current value without being affected by the cycle of the clock CK. If the welding current I exceeds the set current value at a point of time on the leading edge of the clock CK, then the control unit (20) holds the control pulse CS inactive or low till a point of time on the leading edge of the next clock CK.
