Friction Welding

Friction Welding is a welding method were the connection happens in a firm state. The method prevails because different materials can be connected very efficiently and with a very high quality. The actual implementation and analysis of the process is made difficult through phenomenons like plastic deformation, high temperature gradients, relative velocity and extending rates, as well as the influence onto the rub performance and material performance of the latter.

Because of this it is of great importance to understand the underlying mechanisms and their impact through the parameters of the process, as well as the consequences on the quality of the connection. Through this knowledge the latter can be risen, the error rates can be reduced and ideas of solutions can be passed on to new requirements
On this area, the institute of material science of the Technical University of Graz is involved in different projects and through this experience emphasis is put on the following:

optimizing parameters from experimental data and usage of neuronal webs

interrelation between process parameters and quality of connections

analysis of the thermal flow with inverse approach

FE modelling (thermal-mechanic and thermal metallurgic)

forecast of the development of structures (size of thermal influence zones, buckling channel, deformation performance)

From different research projects, quite a few publications are available.
