The new TruPulse pulsed solid-state lasers from Trumpf (www.us.trumpf.com) feature a burst function that boosts the average power briefly and increases pulse frequency. The company says this reduces the welding cycle in applications in which multiple spot welds are needed. Longer pulses of up to 50 milliseconds can be used on such applications as welding a closed, circular seam with one pulse. The laser has an average power range of 20W to 150W at a maximum pulse power of up to 10 kW.

In addition, Trump will introduce changes in late October to its line of flatsheet laser cutting machines with integrated automation. The company says these changes include a compact enclosure over the laser heat that is 75 percent smaller than a conventional enclosure and one-fourth its original size.
