Wood bonding by vibrational welding

Journal of Adhesion Science and Technology, 2003
—Mechanically-induced wood welding, without any adhesive, is shown here to rapidly yield wood joints satisfying the relevent requirements for structural application. The mechanism of mechanically-induced vibrational wood fusion welding is shown to be due mostly to the melting and flowing of some amorphous, cells-interconnecting polymer material in the ...

Parameter interactions in two-block welding and the wood nail concept in wood dowel welding

Journal of Adhesion Science and Technology, 2005
The interactions between parameters found to be determinant in wood dowel welding by high speed rotation have been evaluated. Of these, the interactions that proved to be the most significant, in descending order, were rotation rate/dowel moisture content, followed by rotation rate/ethylene glycol, and finally, at a lower level of significance, the ...

Wood welding: A challenging alternative to conventional wood gluing

Scandinavian Journal of Forest Research, 2005
The recent finding of a new way to assemble two pieces of wood by mechanically induced wood welding opens a new and challenging perspective for producing more environmentally friendly wooden products, i.e. without glue. This process, recently applied to solid wood, needs to be better understood in order to investigate the dependence of the variability ...

Influence of Wood Welding Frequency on Wood Constituents Chemical Modifications

Journal of Adhesion Science and Technology, 2009
Interesting chemical differences betwen weldlines obtained at 100 Hz and 150 Hz frequencies in linear vibration wood welding were observed by FT-IR and 13C NMR. An increase in the proportion of unoxidized phenolic groups in the lignin is observed by FT-IR and the increased joint strength observed is ascribed to the improved adhesion derived from this ...

Vibration welding of heat-treated wood

Journal of Adhesion Science and Technology, 2006
Vibration welding of wood that has been preheated according to an industrial two-step process indicates that such wood can be welded and can yield welded joints of good strength. The joint strength is, however, markedly lower than obtained when welding non-heat-treated timber.

Wood blockboards for construction fabricated by wood welding with pre-oiled dowels

Journal of Adhesion Science and Technology, 2013
Holding wood pieces together by rotationally welded dowels can be used to make blockboard panels with the dowels inserted in the side of the wood substrate slats. Pre-oiling the dowels with sunflower oil: (i) eases their insertion in the pre-drilled substrate, (ii) allows the insertion of dowels to a much greater depth by its lubricating action for ...
