Currently, welding is commonly used to join ferromagnetic metals by arc welding, spot welding, friction welding, etc. Welding on ferromagnetic metals is easier to do than on non-ferromagnetic metals. Aluminum is a non-ferromagnetic metal. In this study, friction welding with aluminum was carried out. The welding process is carried out with variations in the frictional rotation speed of 2300 rpm and 3100 rpm, at a pressure of 100 psi and a time duration of 30 seconds. Tensile tests are carried out on the welding results. From the tensile test results obtained tensile strength 85.77 N/mm2, yield strength 68.96 N/mm2, strain 7.98 % on welding with a rotation speed of 3100 rpm, breaking in the welding area. The obtained tensile strength is 81.88 N/mm2, yield strength is 75.89 N/mm2, strain is 3.66% on welding with a rotation speed of 2300 rpm, and breaks in the welding area. The amount of rotation speed during the friction welding process affects the strength of the joint. [ABSTRACT FROM AUTHOR] |
