| Abstract:
The insertion of dowels into solid wood for furniture manufacture has been used for centuries. However, recently, this simple technology has been upgraded. The objective of the research was to evaluate and compare the tensile strength of the joints made by wood dowel using new method of “ wood welding” and classical method of “ using of glue” . Variables included dowel joints method (welding joint and joint with glue), dowel diameter (10 and 12 mm) and dowel surface texture (smooth and grooved). Members joint and dowel wood were hornbeam species (Carpinus betulus) and glue was polyvinyl acetate (PVA). The results showed that the types of joints, diameter and surface texture have significant effect on the tensile strength. The welded joints, dowel diameter 12 mm and grooved surface has the highest tensile strength compared to other samples. The results also showed that in all cases, the strengths of the joints made by welding was higher than the joints made by PVA glue.
