Sažetak
Wood 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 generated by mechanical friction of the elements being connected. The results of various researches have shown that after 20 seconds of cooling of the welded wood the weld joint strength reaches 70% of the maximum value obtained after 15 minutes of cooling. Such properties of the weld joint enable the vibration welding of multilayer wood panels. The cell structure in the interface area of timber is completely destroyed, while in the welding area the density is increased due to the destruction of wood cells. The cell walls are broken, which is the result of the exposure to high temperatures, mechanical pressure and chemical process which occur during the cooling stage. Only natural materials are used in wood welding, which makes these products eco-friendly. In case of recycling, welded products may be disposed of just as natural timber, without the release of toxic substances. This paper illustrates the up-to-date world knowledge and results of the application of wood welding techniques at the Faculty of Forestry.
