Welding of ultra-high molecular weight polyethylene and its composite to increase the sealing of lining coatings

This article proposes the use of magnetic induction for ultra-high molecular weight polyethylene (UHMWPE) welding. The conducted mechanical and structural studies confirm the high efficiency of the method of welding ultra-high molecular weight polyethylene and its composite using magnetic induction with a ferromagnet in the form of a steel mesh. The chosen optimal welding mode allows obtaining a high-quality weld. It has been established that the preservation of the strength properties of the weld at the selected welding mode at the bulk level of UHMWPE is due to the controlled local heating of the material in the welding zone and increased adhesion at the UHMWPE-metal mesh interface.
