Hybrid laser welding system

Sept. 3, 2010
Erlangen, German – LPKF Laser & Electronics AG has made improvements to its TwinWeld hybrid welding system. Instead of complex clamping tools, this method requires only the use of an inexpensive component holder. In addition, an integrated rotary indexing table supports two stations: a loading/unloading station and a welding station.

Erlangen, German – LPKF Laser & Electronics AG has made improvements to its TwinWeld hybrid welding system. A new high-performance welding head and a compact housing are the stand-out features of the new series.

In hybrid welding, the laser beam is surrounded by a thermal field that enlarges the process window, increases the welding speed, and eliminates the need for a tempering process.

"Instead of complex clamping tools, this method requires only the use of an inexpensive component holder. In addition, an integrated rotary indexing table supports two stations; a loading/unloading station and a welding station – of large car lights for instance," explains Frank Brunnecker, VP, Laser Welding Business Unit.

In the redesigned inline module "LPKF LQ-Integration," the development engineers succeeded in significantly reducing the dimensions of the welding head. One or more heads can be installed in space-saving positions in the customer’s own layout. The laser source and the controls are installed independent of the heads in a separate cabinet.
