초록

A study on friction welding of chrome molybedenum steel(SCM440) to carbon steel(S45C) is examined experimentally through tensile test, hardness test. So, this paper deals with optimizing the welding conditions and analyzing various mechanical properties about friction welds of SCM440 to S45C steel. The tensile strength of the friction welded joint was increased up to 100% of the S45C base matal under the condition of all heating time. Optimal welding conditions were n=2,000(rpm), $P_{1}=60(MPa)$, $P_{2}=100(MPa)$, $t_{1}=4(s)$, $t_{2}=5(s)$ when the total upset length is 5.7(mm).
