LPKF Laser & Electronics AG's LaserWelding division has added reflection diagnosis to verify successful laser-welded of plastic parts.
LPKF showcased the technology at K 2010 in
Reflection diagnosis uses the physical effect of light reflection at boundary surfaces. Before welding, there are two boundaries between the two parts. When laser light impinges on these boundaries, a certain amount of light can be reflected, but since areas that have been welded together have no such double boundary, the amount of reflected light is reduced.
Reflection diagnosis can evaluate the quality of a welded seam during the actual welding process.
