Influence of Various Wood Species and Cross-Sections on Strength of a Dowel Welding Joint

Rotation welding is a new method used in wood welding. Heat that develops due to the friction on contact surfaces softens and melts the wood structure (melt is produced). When the friction stops, the melt cools down and solidifies forming a firm joint. This research is based on the examination of th...
