Resumo
Friction welding (FRW) is an important commercial solid-state welding process in which
coalescence is achieved by frictional heat combined with pressure. The objective of this work is to
analyze the microstructure and the mechanical behavior of the copper alloy UNS C64200 – bronze-aluminum-
silicon, as well as to raise the ideal welding parameters so that there is adequate weldability
after process of continuous-drive friction welding. Regarding the analysis of the microstructure,
scanning electron microscopy was used to characterize phases. The mechanical properties were
evaluated by means of a hardness test of the center of the welded joint, traversing the entire extent of
the thermally affected zone. Results show that the UNS C64200 alloy, when subjected to conventional
friction welding, behaves satisfactorily in terms of weldability, without the appearance of cracks or
defects arising from the temperature characteristic of this process, as well as good hardness with
values above the minimum established in norm and higher than the base material.
