Material and methods: 24 welded samples of dimensions 200x2
Aim of study: In this study, it was aimed to determine the shear strength after water immersion and observe bond-line density of the welded birch wood.
Material and methods: 24 welded samples of dimensions 200x20x20 mm(3) (LxTxR) were prepared from sapwood of birch wood (Betula pendula). Shear strength of welded birch at 24h and 48h water soaking were investigated.X-Ray CT-scanning was used to monitor the density profile of welded bond-line.
Main results: The results showed that shear strength decreased slightly with increasing water immersion time. The decreasing of the average shear strength, caused by immersion for 24h and 48h were 60.25% and 78.9%, respectively, compared to control sample. With the welding process, a significant change in density was observed in the welding bond-line. As a result, the X-Ray CT scanner shows that it works effectively on wood material.
Highlights: The results of this research revealed the applicability of a new method alternative to traditional mechanical fasteners (nail, screw etc.) or gluing. The availability of welding combining method in the field of wood engineering should be explored widely and more studies are recommended for appropriate parameters.
