In this research, dissimilar joints of aluminum 6061 T6 and galvanized steel A36 were fabricated by GMAW (gas metal arc welding). It was possible to prove that the formation of FexAly phases was directly proportional to the voltage increase. A larger intermetallic was obtained and that the resistance to failure by the joint is lower. Temperatures reached in the process ranged from 600 ° C to 1000 ° C.
The friction welding (FW) process for aluminum joints 6061 T6 and 304 stainless steel does not give acceptable results in terms of compound formation, despite reaching temperatures close to 550 ° C. The union presented in the interface is mechanical, which is attributed to the fact that the thermal input is not sufficient for the separation of the phases in the interface, and the thermally affected zone does not reach suitable transformation temperatures to obtain the compound.
