AlhimniRusydi, Punky (2016) Pengaruh Friction Time Dan Friction Pressure Terhadap Distribusi Temperatur Metode Pengelasan Cdfw Logam Al-6061. Sarjana thesis, Universitas Brawijaya.
Abstract
Riset Continous drive friction welding (CDFW) berkembang dengan pesat dikarenakan tuntutan proses pengelasan yang murah, cepat dan aman. Mekanisme CDFW yaitu pengelasan yang memiliki sumber panas berasal dari gesekan kedua permukaan kerja itu sendiri yang semakin lama akan menghasilkan panas dan menyatukan dua material. Penelitian ini bertujuan untuk mengetahui pengaruh friction time dan friction pressure terhadap distribusi temperatur benda kerja yang dihasilkan dari proses pengelasan CDFW. Material yang digunakan yakni Al-6061 dengan data temperatur rekristalisasi sebesar 315,560C dan titik cairnya sebesar 6600C. Dimensi benda kerja panjang sebesar 5 cm dan diameter 2cm. Penelitian ini menggunakan software berbasis elemen hingga. Modelling diset dengan cara memberikan rotational speed 1200 rpm pada spesimen 1 dan memberikan friction pressure pada spesimen 2. Pada material Al-6061 diberikan friction time dengan variasi 1s, 3s, dan 5s. Variasi friction pressure yang diaplikasikan pada benda kerja yakni 35 Mpa, 40 Mpa, dan 45 Mpa.Hasil penelitian menunjukkan bahwa semakin besar friction pressure dan friction time menyebabkan semakin besar distribusi temperatur yang dihasilkan pada proses pengelasan CDFW. Temperatur tertinggi dihasilkan pada variasi friction time 5s dan friction pressure 45 Mpa yakni 690,5300C. Prediksi penyambungan yang baik bilamana harga temperatur ZPl (fully plasticized region) diantara temperatur rekristalisasi dan titik cair dari material yang diproses dengan CDFW. Berdasarkan asumsi tersebut maka variasi friction time 5s dan friction pressure 40 Mpa memungkinkan hasil pengelasan paling baik, dimana variasi ini menghasilkan temperatur pada range 315,560C dan 6600C.
English Abstract
Research continuous drive friction welding (CDFW) is growing rapidly due to the demands of the welding process is inexpensive, fast and secure. CDFW mechanism that welds have a source of heat comes from both the surface friction of labor itself that the longer it will generate heat and uniting the two materials. This study aims to determine the effect of friction time and friction pressure against the workpiece temperature distribution resulting from the welding process CDFW. The material used ie Al-6061 data for 315,560C recrystallization temperature and melting point of 6600C. Workpiece dimensions of 5 cm long and 2 cm in diameter. This study using finite element-based software. Modelling is set by providing a rotational speed of 1200 rpm in the specimen 1 and provide friction pressure on the specimen 2. In the Al-6061 material given friction time with variations 1s, 3s and 5s. Variations friction pressure is applied to the workpiece that is 35 MPa, 40 MPa and 45 MPa.Hasil research shows that the greater the friction pressure and friction caused greater time temperature distribution generated in the welding process CDFW. The highest temperature variation of friction time 5s and friction pressure 45 MPa namely 690,5300C. Prediction splicing good price when temperatures ZPL (fully plasticized region) between the recrystallization temperature and the melting point of the material being processed with CDFW. Based on these assumptions, the variation of friction time 5s and friction pressure of 40 MPa allows most excellent welding results, which variation produces a temperature in the range of 315.560C and 6600C.
