Abstract

Investigations concerning opportunities to apply the friction welding technique for joining dissimilar and graded materials are considered, starting from the advantages offered by this process in assem- bling parts for manufacturing equipments parts and automotive industry components. Experiments have been carried out on friction welding of heat treated 42CrMo4 with C45 steel and with the solu- tion treated X6CrNiTi18–10 steel, as well as on joining copper with Al alloys. Metallographic obser- vations and hardness measurements are performed in order to detail the peculiarities of the process of making joints that are difficult to obtain by conventional electric arc welding.
