In this article we investigate the influence of combined physical field, magnetic ultra sound one in this case, on the parameters, defining strength characteristics of adhesive joint. As a research adhesive subject we define synthetic polymer glues, widely used in wood processing industry, and as a substrate – the samples of oak wood. Quality of glue joints is evaluated on the basis of analysis of results of adhesive microstructure research, substrate species, duration of technological process of synthetic polymer glues modification and break test for shear parallel to the grain of control samples. On the basis of microstructure and x-ray structure analysis it is defined that increase in strength of woof adhesive joints is explained by structure ordering of glue composition melt, processed by magnetic ultra sound field.
