Laser technologies are wide-ranging applications in various fields such as manufacturing, medicine, research, entertainment, and more. They are used in processes, such as, for cutting, welding, marking, engraving, surgery, spectroscopy, and many other purposes, owing to their precision, versatility and etc. Birch plywood is a type of manufactured wood product made from thin layers of birch veneer bonded together with special glue under high pressure and heat. It is known for its strength, stability, and visual look, making it a popular material in woodworking, furniture making, construction, and other applications. This study investigates the effect of laser textured treatment on the adhesion properties of birch plywood surface using PVA wood glue. A SUNTOP ST-CC9060 CO₂ laser with a wavelength of 10640 nm was used to texture birch plywood samples with different power and speed parameters, including untreated samples (base). Dino-Lite Edge AM7115MZT digital microscope and an OLYMPUS LEXT OLS5000 laser microscope were used to measure the samples. The depth and width of the treated area were measured for these samples and graphs were created to analyse the results. Material testing machine Zwick/Roell Z150 was used for tensile and shear analysis of the processed samples. These results show that laser-treated samples have an effect on glue adhesion compared to untreated samples. The study provides valuable insight into the optimization of laser processing parameters in adhesion, and also shows the potential of this type of adhesion to improve the quality of the adhesion properties of laser-treated birch plywood.
