Abstract

An approach is developed to find the values of the friction welding parameters to be used in the joining of Mg alloy sheets with thickness of 1.5 mm. A set of laboratory trials, based on the design of experiment method, is performed in order to determine the conditions under which the welding operation is feasible. In particular, a 2k factorial design (k=3) is used with two different configurations. In the first configuration the rotational speed, the welding speed and the presence/absence of the pin (in the tool) are considered, whilst in the second, performed under “no-pin condition”, the rotational speed, the welding speed and the shoulder diameter are varied. The results show a strong beneficial effect on the tensile strength of the joint, under the “no-pin condition”, when the shoulder diameter is increased.
