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 lead to the solidification of the melt and creating a solid compound. The paper will investigate the influence of the rotation frequency (1520 min- 1) and the welding depth (20 mm) on the temperature in the rotary welded joint. The welding direction is perpendicular to the direction of the fibres with constant welding time. The temperature is measured by means of measuring probes set vertically on the welding direction. The position of the measuring probes is defined in this study. The probe closest to the surface (probe 1) achieves an average temperature of 184 ° C. Probe 4, which is 16 mm away from the surface, achieves at least the average temperature of 68 ° C. The average embedded force is 1631 N. The welding of pine wood is shown in a three-dimensional rectangular coordinate system.
