Joining wood by friction welding [PDF]
Holz als Roh- und Werkstoff, 2005 At the Chair of Timber Constructions of the Swiss Federal Institute of Technology in Lausanne (EPFL) tests were carried out to join wooden work pieces by friction welding without any additional welding deposit. It could be determined that this kind of technology, which is mainly used for thermoplastics and metal, can also be applied to wood. Tests were

Welding of wood in the presence of wollastonite
BioResources, 2020 The use of wollastonite as a natural additive for the welding of Scots pine improved the water resistance and shear strength of the welded joint. The X-ray computed tomography images revealed that the welding of Scots pine with wollastonite could postpone crack formation in the welded joints.

Welding of thermally modified wood and thermal modification of the welded wood: Effects on the shear strength under climatic conditions [PDF]
BioResources, 2021 This work investigated how thermal modification affects the shear strength of welded joints under different climatic conditions. The order of the thermal modification, before or after the welding, was investigated for its effect on the shear strength of the welded wood. Two groups of thermally modified specimens were prepared in a laboratory kiln under

Parameters of wood welding: A study with infrared thermography [PDF]
Holzforschung, 2006 Abstract Welding of wood is a well-known joining procedure that offers several advantages over traditional mechanical fasteners or gluing. During welding, extensive solid-state transformation phases occur in the so-called melting zone and the heat-affected zone. The nature and the extension of such transformations are correlated to the energy input and

Influence of Biological Pretreatment of Wooden Dowels on Strength of Rotary Welded Joints
BioResources, 2023 Welding wood achieves joints whose strength is comparable with the strength of glued joints. When welding, the top of the dowel is not welded because of the lack of melted lignin.
