This research aim is determined to study the effect of flux-cored arc welding parameters on the mechanical properties of JIS-S50C carbon steel hard-faced weld metal. This work is also studied a relation between mechanical properties and microstructure of hard-faced weld metal. The experimental results are summarized as follows. 1) Increasing the welding current is directly affected to increased hardness and wear resistance of a hard-faced weld metal. 2) Metallographic examinations of the hard faced weld at the top surface are showed the increased some elements which able to increase the hardness of weld metal i.e. silicon, vanadium, chromium, manganese and molybdenum. The increased hard-faced weld layer is affected for the hardness increasing and wear resistance of the weld metal because of their increased reinforced elements. Optimized welding parameters are produced for the maximum hardness of 837 HV which the minimum weight loss of 0.0218% i.e. that is not welded the first welded buffer layer, using the welding current of 210 A, the welding speed of 300 mm/min and the 3 hard-faced weld layers.
