In order to examine the effect of base metal condition of pure aluminium of friction weldability, full annealed and cold-worked aluminium were prepared.
Vickers hardness of the cold-worked aluminium was 27-30 compared with 20-22 of the annealed. Experimental results were as follows;
Cold-worked base metal for friction welding reduced the defect to weld interface, and gave better reproducibility of sound joint, compared with annealed base metal. And suitable welding condition can be broadend by using cold-worked base metal.
