摘要：

joining of dissimilar metals is one of the most essential needs of industries. Manufacturing with joint of alloy steel and normal carbon steel is used in production, because it decreases raw material cost. In this study,joining of AISI 4140 steel (medium carbon and low alloy steel) and AISI 1050 steel (medium carbon steel) was successfully achieved. Mechanical properties, macro and micro structural investigation of materials joined with this process were completed: joint strength was tested and optimum welding parameters were obtained. Moreover, temperature change of the weld zone was measured with an infrared temperature measurement device during welding; and the effects of the friction welding parameters on welding zone temperature were investigated. The highest tensile strength acquired in the welded specimens is 6% higher than parent AISI 1050 steel and the lowest tensile strength obtained was 1.9% lower than the parent AISI 1050 steel.
