The New Knowledge of Environmentally Friendly Joints Made by Thermal Drilling

Abstract

The contribution deals with possibilities of new progressive technologies in materials joining processes. By using of friction, physical factors as temperature and thermal conductivity in joining, we can increase the quality of material joining and can join of various types of material. There is also shortage the production time, provide automation in operations is possible, spare of economical expenses and also we can protect the environment. The product increasing of automobile industry, pipe industry, development of mechanical products, materials, design of joining in civil engineering force the producers to accelerate the production and to utilize new technologies.
