摘要： An inverter resistance welding control or power supply apparatus includes a clock generator which generates a clock signal defining a switching cycle of an inverter in a resistance welding machine, a device for preselecting a predetermined reference value corresponding to a desired current peak, a current sensor for detecting primary or secondary current of the welding machine, and an inverter control for controlling the inverter on a switching cycle-by-cycle basis. Specifically, the apparatus turns on the inverter in response to a leading edge of the clock signal, and turns the inverter off either when the current detected signal has reached the reference value or when the clock signal has reached a trailing edge. The control apparatus further includes a magnitude evaluator for measuring a magnitude of the current from the detected signal, which magnitude is expressed in root mean square, arithmetic mean or averaged peak value. The control apparatus further includes a reporter monitor which reports, based on the measured results of the current, information useful to determine normal or defective operation. There may further be provided a lack-of-secondary current detector for operatively and reliably detecting a lack of secondary current by monitoring the primary current.

摘要： A single terminal unit is provided to automatically adapt to various types of control apparatus for controlling resistance welding or laser beam processing by merely connecting the terminal unit to the control apparatus via a communication interface. In an initialization mode, a CPU in the programing unit verifies a machine ID registered therein with the machine ID of the control apparatus currently connected to the programming unit via the communication interface (C1-C8). If not matched, the CPU requests the control apparatus to send an application program (C4). In response to the request, a CPU in the control apparatus reads, from ROM, the stored application program and transmits (downloads) it to the CPU in the programming unit. The CPU in the programming unit receives the application program from the control apparatus and writes it into a program read/write memory (C5). It also writes the machine ID of the control apparatus, as newly registered machine ID, into the memory at a predetermined location. Thereafter, the CPU in the programming unit operates according to the application program downloaded in the program read/write memory.

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： When each weld period starts, a control feeds e.g., a high-level ON signal to switching elements having the associated polarity of an inverter so that the switching elements go on and remain on (step S2). This allows the current to start to flow and rise with a sharp gradient on the primary and secondary sides of a welding transformer. When a current detection signal from a sensor reaches a preset current value I.sub.F for current build-up in that weld period (steps S3 and S4), the control stops the on signal and instead issues a PWM signal to provide a high-frequency (e.g., 10 kHz) switching control of the switching elements (steps S5 to S9).

摘要： An apparatus for controlling resistance welding defines a weld time for series welding as a plurality of (e.g., two) weld periods. In one embodiment, a control successively switches a bidirectional switch in a first polarity during the first weld period so that welding current flows through workpieces of different metals in one direction by passing through a series of welding points of the workpieces. In the second weld period, the control successively switches the bidirectional switch in the reversed polarity so that welding current flows through the workpieces in the other direction so as to compensate for Pertier effect on the welding points. A polarity changing technique is used to minimize welding energy loss in shifting weld periods for better weld quality. In another embodiment, thyristors are controlled such that they are fired in the second half cycle of the supply voltage at an angle smaller than the firing angle in the first half cycle.

摘要： To provide automatic, efficient and effective cleaning before or after laser marking, a control of a laser marker identifies a start number presented on a display and retrieves drawing data and drawing position data of the start number from a memory. The control determines an area to be cleaned from the retrieved drawing data and drawing position data (A3). Then, the control retrieves condition data, such as scanning speed, for an area sweeping-type cleaning mode. An area cleaning scan is performed in which a beam spot of YAG laser beam almost entirely scans or sweeps once an area of the workpiece (A5) surface to be cleaned (A5). The cleaning scan is repeated a predetermined number of times. By the projection of the YAG laser beam onto the area, workpiece surface materials are thinly and lightly melted or sublimated so that stains, such as dirt, are removed as if with an eraser.
