Abstract

During the rotary friction welding process is a joint made at the interface of two materials using the parameters such as temperature, pressure, relative motion speed and the secondary parameter is time. This method offers a wide range of applications, especially when are welded rotating parts. The research is focused on homogenous and heterogenous rotary friction welds between subsequent materials: steel DIN 975, stainless steel 1.4301, aluminum alloy AlCu4PbMgMn, aluminum alloy AlMgSi, copper Cu - ETP, brass CuZn39Pb3. Heterogenous welds were formed by various combinations of the mentioned materials, where the microstructural analysis was performed and the physical nature of the joint formation during rotary friction welding was created. The influence of the geometry on the contact surfaces was monitored on homogenous welds - the results were used in the selection of the effective geometry also in heterogenous welds. Furthermore, sets of homogenous welds were subjected to a static tensile test, a hardness test and also microstructural analysis. Welded workpieces were cylindrical with 10 mm in diameter.
