“Reflection diagnosis gives us an innovative measurement tool to verify
successful welding.” Frank Brunnecker, Vice President LaserWelding at 23.04.2014 LPKF Laser & Electronics AG. As of autumn 2010, reflection diagnosis will Characters: 470
be available as an option on LPKF welding systems. (The company will
present the method at the K show in Germany in Duesseldorf, October 27 to November 3, 2010 – Hall 11, Booth# E04).
LPKF Laser & Electronics AG Reflection diagnosis makes use of the physical effect of light reflection at Laser Plastic Welding boundary surfaces. Before welding there are in effect two boundaries Gundstr. 15 between the components. When light – also laser light – impinges on D-91056 Erlangen
