Wood blockboards for construction fabricated by wood welding with pre-oiled dowels
Journal of Adhesion Science and Technology, 2013Holding 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 ...

Wood dowel bonding by high-speed rotation welding
Journal of Adhesion Science and Technology, 2004High-speed rotation-induced wood dowel welding, without any adhesive, is shown here to rapidly yield wood joints of considerable strength. The mechanism of mechanically-induced highspeed rotation wood welding is shown here to be due, as already observed in vibration welding, to the temperature-induced softening and flowing of some amorphous, cells ...

Influence of Wood Grain Direction on Linear Welding
Journal of Adhesion Science and Technology, 2009Wood grain orientation differences in the two surfaces to be bonded yield bondlines of different strengths in linear wood welding. End-grain-to-end-grain welds of good strength were obtained for both beech and oak woods. The tendency to defibration in end-grain-to-end-grain welding indicated that for wood densities higher than or equal to the density ...

New findings in wood-welding research
2009Bonding of wood by virtue of nogs, without any adhesives and welding, has been done for centuries. If such nogs (wood dowels) are rotated during the bonding with the surface (in controlled conditions) at certain parameters, a firm joint is formed. Rotational welding of wood dowels without adhesives resulted in joints of significant sturdiness.

Performance of Dowel-Welded Wood Furniture Linear Joints
Journal of Adhesion Science and Technology, 2009Comparison of three types of furniture joints such as scarf joints, step butt joints and dovetail joints held together either by one or two welded dowels, glued dowels and steel nails showed that the dowels always gave better shear strength and greater stiffness than the steel nails.

Design of wood products using the method of welding wood
2014Contemporary design is often at the brim of change and is more focused on presenting concepts and designing processes than new products. The scientific community in collaboration with designers has an important role in the development of new constructions implemented in innovative product concepts.

Interior wood joints by mechanical fusion welding of wood surfaces
2004Mechanically induced wood fusion welding, without any adhesive, is shown here to rapidly yield wood joints that satisfy the relevant 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 amorphous cells-interconnecting polymer material in ...

Wood bonding by vibrational and rotational friction welding
2005Mechanically-induced wood welding, without any adhesive yields wood joints satisfying the relevant requirements for structural applications. The mechanism of mechanically-induced vibrational wood fusion welding is due mostly to the melting and flowing of some amorphous, cells- interconnecting polymer material in the structure of wood, mainly lignin ...
