The focus is given to the fundamentals of the spinning laser beam technology for welding of wood fiber composites to thermoplastics.

Spinning laser beam processing excites increasing process efficiency by decreasing the viscosity for various materials. Hence, increasing the process speed is possible without increasing laser power (→ 170%, cal.).

The results are presented by using infrared radiation visualization, shear stress measurements and optical analysis of the weld-seam in comparison to the conventional (linear) laser beam.
