Welding of modified beech wood
2011Wood welding is a mechanical, physical and chemical process during which melt is produced, which then turns into a solid joint after cooling. The paper shows current world-wide knowledge on welding of modified wood while the results of wood welding were received from the Faculty of Forestry in Zagreb.

Joining of wood layers by friction welding
Journal of Adhesion Science and Technology, 2005A welding technique has been developed to join wooden work pieces by frictional heat without any wood glue. During the welding process 'melting' of the surfaces, resulting from the influence of pressure and frictional heat, was observed. Solidification and bond formation between the welded pieces happened during cool down of the heat-affected zone. The

Wood Blockboards Fabricated by Rotational Dowel Welding
Journal of Adhesion Science and Technology, 2011Holding 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. The average results for both tensile and three-point bending tests indicate that a 20° dowel insertion angle yields strength results better than 10° and 0° insertion angles.

Wood welding – a new wood bonding technology
2007Wood welding technologies have been developed as a new way of bonding timber by using high temperature generated by friction and pressure. Timber is assembled without any adhesives. During the process the surface layer of timber (lignin), which is in direct contact with its counterpart, melts due to high pressure and temperature, which is usually ...

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 ...

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.

Study of the solubility and composition of welded wood material at progressive welding times
European Journal of Wood and Wood Products, 2015The solubility in water and carbohydrates/lignin composition after hydrolysis of wood welded by linear friction welding was studied. Welded beech (WB) and welded spruce (WS) were analyzed at welding times (Wt) of 1, 1.5, 2, 2.5, 3 s, and 2, 4, 6, 8, 10, 12 s, respectively.

Wood–bamboo–wood laminated composite lumber jointed by linear vibration–friction welding
European Journal of Wood and Wood Products, 2013The linear vibration-friction welding offers several advantages compared to traditional mechanical fasteners or gluing. This study examines the possibility of applying mechanically-induced vibration welding to the joining procedure of a wood-bamboo sandwich-laminated composite. The result shows that average tensile strength values of the composites can

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.
