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.

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.

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.

Parameter interactions in two-block welding and the wood nail concept in wood dowel welding
Journal of Adhesion Science and Technology, 2005The 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 ...

Comparative potential of alternative wood welding systems, ultrasonic and microfriction stir welding
Journal of Adhesion Science and Technology, 2007 Two alternative welding systems were evaluated for wood welding. Ultrasonic welding produces joints of good strength but it appears to be applicable only to thin wood pieces.

Influence of Wood Welding Frequency on Wood Constituents Chemical Modifications
Journal of Adhesion Science and Technology, 2009Interesting 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 ...

Emission Gases in Linear Vibration Welding of Wood
Journal of Adhesion Science and Technology, 2009Analysis of the gases, vapour and degradation volatiles emitted as smoke from the welding interface during linear vibration welding of beech and oak woods has shown that the compounds in such a smoke are water vapour, CO2, and degradation compounds from wood polymeric carbohydrates as well as from amorphous lignin. For the two hardwoods tested the main

Welding of wood, a new challenge for the wood industry
2004In the years 2001/04 the HSB, R+D department has been investigating possible alternatives to traditional gluing processes. The objective of the project was the development of an innovative gluing and assembling process that would be applicable both economically and qualitatively in an industrial production. This research work, led to the discovery that
