Investigation of Joining Performance and Microstructural Mechanisms of Softwood and Hardwood Dowel Joints via Rotary Friction Welding

BioResources
Rotary friction welding of wood typically uses dowels made from the same material as the base wood or involves specific modifications to the dowels, but these methods have practical limitations and are complex.

Influence of the moisture content on the shear strength of welded wood-to-wood connections

, 2011
Friction welding of wood is an innovative process, able to join pieces of wood without additional adhesives. Because of its hygroscopic properties, the wood matrix absorbs humidity at the surface from the surrounding atmosphere. Its moisture content is strongly dependent on ambient conditions and seasonal changes.
