Influence of surface shapes on the mechanical behaviour of friction welded wood bonds

Yves Weinand, Bernhard Stamm, Benjamin Hahn

Friction welding of wood is a fast and adhesive-free bonding technology for the production of timber joints with good mechanical characteristics making this type of connection interesting for applications in timber construction. However, the moisture stabi ...

Experimental Investigations and Probabilistic Strength Prediction of welded Double Lap Joints composed of Timber

Yves Weinand, Bernhard Stamm, Till Vallée, Benjamin Hahn

Wood-to-wood bonds obtained by means of friction welding are a relatively new type of connections holding high potential to compete with existing structural adhesives, since a load bearing bond is formed almost instantaneously. This paper addresses the que ...

Experimental investigations on welded double lap joints composed of timber

Yves Weinand, Bernhard Stamm, Till Vallée, Benjamin Hahn

Fabrication of wood-to-wood connections by means of friction welding is an relatively new process holding high potential for development. To connect wooden pieces by means of friction welding, they are initially pressed against each other. The rapid moveme ...

Numerical modelling and strength prediction of welded double lap joints made of timber

Yves Weinand, Bernhard Stamm, Till Vallée, Benjamin Hahn

Welding of wood is a relatively new method of joining load bearing elements, which holds the potential to compete with structural adhesion, since it allows for an almost instantaneous bond. First experimental and numerical investigations showed that failur ...

Chemical investigations on the thermal behaviour of wood during friction welding

Bernhard Stamm, Julius Natterer

Friction welding is a new technology in the course of which wood pieces are subjected to circular or linear movements in a welding machine. The wood in the contact zone is heated and melted. Aiming at a better understanding of the thermal alteration of woo ...
