Sažetak
Welding of wood is an innovative way of connecting wood, or pieces of wood, without the use of glue or other binder. The main reason of welding are melting of the welding surface layers of wood (lignin and hemicelluloses) and physical and chemical reactions that leads to the solidification of the melt and creating a solid compound.The subject of this paper is the influence of chemical modified oak citric acid on the strength of welded rotation of beech dowels across the grain in the radial- tangential direction. Samples treated with citric acid had 9 % less strength compared to untreated samples. The modified samples were immersed in water according to the standard HRN EN 204:2003 and had 74 % less strength compared to the unmodified samples. That was to be expected because we already known that welded joint are not resistant to water.
