The newly discovered process of adhesive-free wood welding introduces a non-toxic alternative for many industrial applications. The process consists of heating up the surfaces of two wooden samples by mechanically induced friction and applied pressure. The aim of this case study is to investigate the importance of different wood welding parameters for the strength of the created bond. Experiments have been conducted with varied welding parameters on a novel setup. Shear strength tests yeld the following results: relatively long holding time has a great impact on the bond strength; high welding pressures of 6 bar and above, as well as long welding times, lead to unsatisfactory results; relatively small changes in the frequency of the vibra- tional welding yeld results with significant differences. Using this technique softwood joints can be created with strengths close to the ones, obtained with professional wood adhesives.The newly discovered process of adhesive-free wood welding introduces a non-toxic alternative for many industrial applications.
