This research is to study the mechanical properties of the joints of carbon steel welding, tire friction. In the experimental design
with friction welding. Using carbon steel grades 1040 in diameter and 10 mm long, 100 mm, and then connect with friction using the time to rotate to heat (Tf) was 3 4 5 6 7 8 9 10 seconds and pressure until birth. Friction (Pf) is 15 20 25 30 35 40 45 and 50 MPa, and the study of mechanical properties. Hardness Tester (Harness Test) impact testing, tensile testing, education and metallurgical properties. The results showed that The right time to turn to heat (Tf) is 5 seconds, to the tensile strength of 668.33 MPa pressure right until the friction while rotating (Pf) of 30 MPa will provide value. tensile strength of 658.33 MPa and time to rotate to heat (Tf) was 3 4 5 6 7 8 9 10 seconds, the ability to impact the specimen average of 428.625 J / cm2 pressure until the birth. friction while rotating (Pf) the ability to impact the specimen averaged 38.875 J / cm2.
