摘要： An apparatus for and a method of controlling a laser oscillator for use as a laser source in a machining operation or the like is disclosed. In particular, the present invention compensates for a deviation of an actual input/output characteristic of a laser oscillator from a normal (expected) input/output characteristic due to, for example, aging and the like. The present invention approximates the actual input/output characteristic and stores the characteristic as a pattern in a storage device. In response to a detection of the actual laser output and an external intensity command signal, the present invention refers to the input/output characteristic pattern thus approximated and generates an input intensity command signal for controlling the laser oscillator to accurately produce the desired laser beam intensity irrespective of the deviation between the actual input/output characteristic and the normal characteristic.

摘要： In a laser beam machining method for a wiring board, a machined portion of the wiring board is irradiated with a pulsed laser beam for a beam irradiation time ranging from about 10 to 200 μs and with energy density of about 20 J/cm2 or more, thereby machining the wiring board, for example, drilling for a through-hole and a blind via hole, grooving, and cutting for an outside shape. The laser beam operates at a frequency of more than 67 Hz, and the spot of the laser beam is sequentially moved to different drilling positions for each pulse. After all of many drilling positions in the range of a scan vision are irradiated with the laser beam pulse by pulse, or after the elapse of a time of 15 ms or more from irradiation of the first drilling position, the laser spot is returned to the first drilling position. The spot is sequentially moved once again, and the movement is repeated several times. A pause of 15 ms or more is required between pulses directed to the same drilling position to avoid formation of a thick char layer and projection of glass cloth into the hole.

摘要： A pulsed arc welding for carrying out arc welding or short-circuit transfer type arc welding by utilizing the pulsed discharge generated at the tip of a wire electrode. The propensity of wire electrode curvature causes irregular changes in the contact point of the wire electrode and variations in the arc length between the wire electrode tip and workpieces. Consequently, the invention detects arc voltage and current and checks the instantaneous variation in the arc length. The arc voltage value thus detected is converted to a reference arc voltage variable. Then the detected arc voltage value is compared with the reference value to compute a true arc length. A simulation arc length signal, which varies as welding proceeds, and a reference simulation welding current waveform are set, to compare the simulation arc length signal with the computed arc length signal. The reference simulation welding current waveform is corrected according to this difference signal to form and output a welding current waveform, which is controllable instantaneously to provide an ideal target arc length. Welding can be carried out with stability since the wire electrode is allowed to hold the simulation arc length during each welding process.

摘要： The welding equipment according to the present invention divides the pulsed electric current fed to a base metal in the course of a welding process into a plural number of pulse groups, performing instantaneous control over the base electric current period and the base electric current value applied to each of the pulse intervals of the individual pulses within such a group of pulsed electric currents and to each of the groups of pulsed electric currents, the pulse peak value and pulse width of each pulse, and such instantaneous control over a short circuit period and an arc period in the course of performance of the short circuiting transfer arc welding process, in accordance with the detected arc length, in such a manner that an ideal target arc length is thereby achieved. The welding equipment is capable of achieving the separation and transfer of molten globules to the base metal with regularity and also reducing the fluctuations in the short circuit period and the arc period in the short circuiting transfer arc welding process, offering the advantage that the equipment can control the growth and separation of molten globules without being affected by the phenomenon of magnetic arc blow of the arc and can achieve improvements on the quality of weldments even if fluctuations should occur in the shape of welded joints and in the position of the earthing point in operation with the actual arc.
