Laser power feedback control and optional waveform control functions
■ The Laser can handle a wide variety of workpieces. Up to 32 different settings
for weld schedules using waveform control are available.
■ High-repetition laser output (500 pps max.) supports high-speed seam welding.
■ The welding schedule can be momentarily switched. This permits high-speed
and high-quality welding.
■ For seam welding, output can be set to fade in at the start and fade out at the
end also to smooth overlaps at both ends of the weld.
■ Up to 4 deliveries of laser output, including powersharing and timesharing, are
available. (The beamsplitter and branch shutter are options.)
■ Powersharing permits obtaining uniform outputs for each delivery without
energy loss.
⇒
Simple operations and maintenance
■ For greater convenience, the Laser is designed to allow the operator to work
on the Laser from the front for cumbersome tasks such as wiring and filter
replacement.
■ Remote control is available because the Laser Controller is detachable.
■ As welding schedules are entered on the liquid crystal display, the user can
perform operations easily and accurately.
■ A variety of input and output signals allow the Laser to be connected to
automatic machines.
■ Both the laser energy (J) and its mean power (W) are monitored. If the desired
energy range has been preset and the laser energy is out of the range, the
trouble signal is output. This function is provided for quality control purposes.
■ Use of high-precision optical fiber eliminates the optical axis adjustment
usually needed every time the fiber is removed and reinstalled.
■ Optical fiber detection is available to check fiber connection and breakage. (An
optional output unit with fiber sensor is required.)
■ Using the external communication function permits managing data such as
welding schedules and monitor values in centralized form.
⇒
The factory environment can be improved by space saving.
■ The laser power supply, oscillator, and cooler are integrated into a single piece
for easy transport and installation of the Laser.
⇒ The Laser conforms to the following standards.
