Wood bonding by melting of non-toxic fillers using linear friction welding

Abstract

Wood to-wood welding was shown to yield high quality joints with challenging perspectives for producing new environmentally-friendly wooden products. The same welding technique was recently applied to solder wood by melting of non-toxic organic fillers to generate coalescence though softening and recrystallization of the material across the interface. Researchers have been undertaken to clarify the effect of the fillers on the final proprieties of the joints. To this purpose, three types of fillers were tested and the results were compared with those obtained without fillers. Furthermore, the influence of the welding parameters on the joints’ strength was measured
