Investigation object of this work is determination of regularities of internal and external factors effect on the main physical properties of joints of polymeric composite materials, welded by fusion welding, as well as of joints polymer-metal, and development of effective joining technologies for different types of materials, including dissimilar hard-to-join materials. Topicality of the work is based on the following: currently the number of structural materials is growing up rapidly in various industrial areas. The need to join various materials, including polymers and polymeric composites with various fillers, and with metals is increasing. Fusion welding is a purposeful solution since it provides guaranteed heating of hard-to-reach contact surfaces and obtaining of complex-shapes joints for a wide range of polymeric materials. Basing on the achieved results the method increasing the effectiveness of a metal net like of a fusion element (by modification of the wire surface) was developed. New type of fusion elements basing on polymeric electro-conductive composites is proposed. Technological recommendations concerning fusion welding using modified metal nets and electro-conductive polymeric composites are developed. Possibility to make polymer-metal joints using diffusion mechanism is confirmed for polyethylene-tin samples.
