K 2016: Wobbling at the LPKF booth
LPKF is presenting a brand new technology on booth E04 in Hall 11 at K show 2016. "Wobbling" enables the LPKF PowerWeld3D 8000 to join large components of up to 100 cm x 70 cm with welds of between one and five millimeter width. It can also handle height differences.

"In the automotive industry, more and more components are being manufactured with lightweight plastics. The PowerWeld3D 8000 by LPKF is a system with integrated melt travel monitoring and very short process times". LPKF CEO Lars Ederleh is pleased with the new technology because it considerably extends the range of transmission laser welding.

Wobbling is a process in which the laser beam moves with a small amplitude transverse to the weld path. Height differences that would otherwise lead to altered seam widths can be automatically compensated by adjusting the amplitude. In this quasi-simultaneous process, the weld is tracked several times over, creating homogeneous temperature distribution. Analysis of the setting path and welding time generates reliable data about weld quality. A working area of 100 x 70 x 40 cm³ means the system is ideally suited for large components - for example, interior lights and lamps for the automotive industry. The PowerWeld3D 8000 joins the LPKF-portfolio in the 1st half of 2017. The LPKF booth at K 2016 will showcase construction and sample welds.

Also at the booth is the LPKF PowerWeld 6600, the leading stand-alone laser welding system. It features the company's new design and many improved components. Examples include the waiving of compressed air connections thanks to servo-clamping technology, a soft PLC helps raise flexibility and future viability while the modular design delivers a low-cost production unit offering high productivity.

The software developers from Fürth/Germany have also come up with another innovation. The LPKF CAM software ProSeT 3D works autonomously to suggest welding paths based on CAD data. An integrated editor is used to make manual adjustments to waypoints and welding parameters. This system quickly produces welding processes from component layouts - in only minutes. The laser welding system runs LPKF WeldPro software. When in operator mode only that production data and those commands necessary for production are available, while developers have access to all process data and can even modify individual parameters.

Both welding systems and the software will be showcased at K from October 19 to October 26, 2016 at LPKF booth E04 in Hall 11.
