Welding of polymer and wood composites using laser radiation
Laser beam transmission welding is an innovative and promising technology for many industries as the automotive, electronic and medical industry. Extension to application of this technology to wood components makes it also interesting for the woodworking and furniture industry. Therefore, the Laser Zentrum Hannover e.V. (LZH) has carried out several investigations in the field of welding of fiber reinforced thermoplastic and wood composites with polymers. Focus is given to the determination of the weldability and weld behavior of different thermoplastic and wooden materials in matrices relevant for recent industrial applications. At the LZH, laser beam sources at different wavelengths are examined, e.g. high power diode laser (810 nm, 940 nm) and Nd:YAG laser systems (1064 nm). New approaches using thermographic methods for an easy and fast evaluation of materials qualification regarding their weldability will also be presented. Different plastic and wood components taking into account properties like filling content are investigated. Since natural fiber composites have strong material inhomogenities and anisotropic structures, special process strategies for their application have been developed and are presented in this paper.
