Abstract

Kata kunci: waktu gesek, las gesek, tekanan tempa, baja karbon rendah, pipa airAbstractThe welding process of the carbon steel pipe will be abit difficult since during welding it is needed rotarymovement of the pipe in order to the operator easily to join the welding. This difficulty can be overcome byapplying friction welding technology. This method is strongly influenced by friction time, rotation velocityand pressure of the pressing. Therefore it is needed the research to joint the carbon steel pipe by applyingfriction welding. The variation time for the friction welding test were 15, 20, 25, 30 and 35 second. Theprocess parameters were keep constant. The friction welding machine was operated with 4125 rpm, frictionpressure 15 kg/cm2 and pressure about 70 kg/cm2.The specimen obtained was tested for metallographic,hardness test. The metallography test was done recognize the microstructure and the hardness test wasconducted to obtain the hardness distribution in the original material, in the HAZ region, and in the weldingmetal. Analyses for the value of hardness in the three region namely, origin metal, HAZ, and welding metalwill be related to the change in microstructure.The longer the time for the friction, the temperature increaserespectively. But the increase the temperature affect on the upset value become larger and the samplebecome shorter. The research for joining with friction welding 4125 rpm, friction pressure 15 kg/cm2 andthresure 70 kg/cm3 can be concluded that frinction time that is recomended is 35 second.Friction weldingmethod can be applied for the joining low carbon steel pipe. The microstructure in the joining was found notsignificant change that mean there is no change in mechanical properties

Abstract

Producing of component by machining process can yield component defective. That defective in crack form, although it probably is very litlle. If that defective is applied by a syclic load, the defective exist will propagate with a propagation rate until a limit where that structure is not able to restrain load applied to it. In this research, the specimen to be used was plat Al 2024 T3 with open hole, constant diameter and different distance between hole. Testing to be done by giving fatique load with ratio 0,3, according to ASTM standard E-647-93 (1994). The data to be collected were crack length and the number of load cyclic. Further, it is calculated crack propagation rate (da/dN) toward strength intensity factor (?K). The result of investigation shows that crack propagation rate curve of strength intensity factor function in the Paris area has Paris constant m = 1,163 until 4,2, and value of C = 1,69E-12 until 9, 34E-09
