TruPulse Pulsed Solid-State Laser
Description
The TruPulse laser was developed from the increasing requirements users placed on the laser's capabilities. The laser series is used in the automotive industry in the manufacture of sensors, actuators, and fuel injection components. Pulsed Nd:YAG lasers are also used in the production of consumer electronics, precision machined components, and medical devices—primarily to weld and cut instruments and implantable devices.
Optimized for the customer's individual requirements, TruPulse features several innovations. The burst function allows the average power to be briefly exceeded and increases the pulse frequency, reducing the welding cycle (e.g., applications requiring multiple spot welds). Quasi-continuous seam welds are possible with longer pulses of up to 50 ms. This enables a closed circular seam to be welded with one single pulse by moving the component under the focusing optics. The maximum mean power and pulse energy, focusability, and beam quality can be adjusted depending on the requirements of the application area.
The laser enclosures are compact and mobile with a removable touch-screen control panel with a turn-push knob to simplify setting output parameters. Real-time power control provides very high pulse-to-pulse energy and power stability.
The solid-state laser's average power ranges from 20 to 150 W pulse power of up to 10 kW. Within this range, beam qualities of 4 to 25 mm*mrad are possible. The lasers in this power class can all be supplied with an air-cooled chiller or water/water heat exchanger. With up to 6 laser light cables, the laser can be used by several workstations. Focused spot sizes from 50 to 300 um are possible due to the wide range of fiber optic cables available (i.e., 100 to 600 um) and processing optics. This feature used in conjunction with the laser’s excellent beam quality provides an enhanced processing window.
With a selectable pulse width between 0.2 to 50 ms, and pulse energies from 0.2 to 90 joules, the user has maximum flexibility for a wide range of applications—from micro welding to joining of aluminum, stainless, platinum or nitinol. The excellent pulse stability allows precision welding of thin foil, fine wire, and thin-walled tubing. TRUMPF TelePresence provides the option for service technicians to securely access the lasers for remote maintenance regardless of their location.
Specs
- Individually adaptable lasers due to the broad product portfolio and the modular layout of the TruPulse
- With real-time laser power control, the exact power you select is the power at the workpiece
- The laser compares the pulse shape you have chosen with the actual pulse shape in a 10 μs cycle
- With the burst function, you can temporarily increase the average power several times over
- The WeldAssist option provides suggested values for all of the process parameters depending on the material and welding depth
