Plymouth, MI—In the automotive industry more than 10,000 cars are laser welded every day. The laser of choice has become the high-power solid-state (Nd:YAG) laser. Trumpf is said to be the only laser manufacturer that offers both high-power lamp-pumped and diode-pumped solid state lasers, making it possible for users to find the right high-power laser for their application.
The company's lamp-pumped CW (continuous wave) Nd:YAG lasers, using arc lamps, produce output power to 5 kW with beam quality less than 25 mm/mrad. Because 20 percent of the laser power is reserved for lamp aging and guidance, the company can guarantee specific power at the work piece. With 2 kW, and higher power, it is possible to weld reflective metals with thermal-conducting properties such as aluminum and copper.
Trumpf's diode-pumped solid-state lasers are highly efficient (10 percent more than lamp-pumped) devices that can produce outputs up to 6 kW (4.5 kW at the work piece). Their diode-pumped laser design allows up to 1 kW to be produced per cavity.
All these lasers can have the output beam guided to the work piece via an optical fiber cable and they have the ability to connect up to six of these cables at any time. Trumpf's lasers feature the latest LCU generation and the company's Teleprescense capability.
