It is well known that polyethylene products take the major share on industrial and trade markets. At the same time, welding of these products is widely used in various fields of technology. This research item is highly studied, but new trends of applications require effective technologies of joining of polymers with dissimilar materials, such as metals. Up to today, such joining is carried out by adhesion bonding, but novel effective methods of other type joining are still actual. 
In course of our research, joining experiments were conducted with dissimilar materials, namely high-density polyethylene and tin. The choice of this pair of materials was due to similar melting temperature of both materials, which is less then temperature of thermal degradation of polyethylene. One of the important factors in conducting of these experiments was to provide the same cooling rates of both materials. Taking into account state-of- art, the research presents results of complex studies of formed nanostructures in polyethylene/tin joint, its thermophysical and operational characteristics.
