| Abstract | ||
| In this paper , two types of material are used , the first is medium carbon steel and the latter is high speed steel . These materials welded by friction welding for two samples ( Similar And Dissimilar ) . The optimum conditions for welding had been select by single factor method .Which represent that the optimum conditions for similar materials are : (12 sec ) for friction time, (2.2MPa ) for forging pressure and (0.8 MPa ) for friction pressure , So, for dissimilar materials that are : (16 sec ) for friction time , ( 2.7 MPa ) for forging pressure and (1.4 MPa ) for friction pressure . The experimental results indicated that the tensile strength of the welded joint of similar material was about of (92%) from the base metal strength while in dissimilar case , it was ( 70%) . | ||
