Sažetak
Wood welding is a process which includes both chemical and physical reactions. Heat forms during friction, melting and softening the structure of wood. When the melt cools, a firm joint is formed. Dowels are welded to the surface using rotary welding techniques. This paper studies the influence of moisture content on the substrate and the impact of the dowels on the shear strength of welded joints. This study covered nine groups of samples with different moisture contents and parallel and perpendicular orientations of fibres in the substrate and dowels. The best results were recorded for the sample group (P8M8P) with 7.7 % moisture content in the substrate and dowel. The group of samples with low moisture content (P4M8O) had the worst results, with4.8 % 7.7 % substrate and dowel moisture content, respectively. We concluded that the moisture content in the substrate is the most important parameter for the quality of weld, while the moisture content of the dowel does not play such an important role.
