New Ecological Technique for Soldering of Metallic Materials

Abstract

The performances, qualities and extraordinary development potential of the friction stir welding process (FSW) are well known in the world, both in the scientific and industrial areas. The innovative technical developments, based on the principle of the FSW process, conducted at ISIM Timisoara, as well as the results obtained so far have put the foundation for initiating a new method for bonding of materials, namely friction stir soldering. The principle of the new soldering process is based on important features of the FSW process. The paper presents the results of a program of experiments, which had as its main objective checking whether the new proposed soldering process is viable and applicable. Positive results were obtained by the soldering tests of copper (Cu99), brass (CuZn39Pb2) and steel (S235). Promoting this new environmentally friendly process of soldering is beneficial, because it complies with the current trends worldwide regarding both the environment and health.
