Abstract

Dari segi kekuatan, ketahanan terhadap korosi dan ketahanan terhadap buckling, baja tahan karat AISI 304 menjadi salah satu pipa dengan luas penampang segi empat yang banyak digunakan Namun, proses bending konvensional dengan mekanik memiliki banyak keterbatasan pada bending radius dan diameter pipa yang akan ditekuk. Sehingga, diperlukan penelitian lebih lanjut untuk mencapai hasil proses laser bending yang optimal. Analisa yang digunakan adalah termal dan mekanik. Parameter - parameter yang digunakan adalah bentuk penampang persegi dan persegi panjang persegi, laser power , scanning speed, scanning path dengan masing-masing dua variasi. Variasi tersebut dianalisa untuk mendapatkan hasil proses laser bending yang paling optimal. Dari simulasi yang dilakukan menghasilkan tegangan, distorsi dan bend angle terbesar adalah skema circumferential dengan power 1500W scanning speed 10 mm/s dengan nilai tegangan maksimum 414 MPa. ======================================================================================================================== Based on its advantageous properties or characteristic, stainless steel AISI 304L is widely used as square pipe materials. Tube bending is an important manufacturing of pipe products. There is a new developed method of bending process, named laser forming.This manufacturing technique use laser beam as a heat source. However, conducting an experiment with this method is time consuming and expensive. Having said that, this experiment has been done by finite element method. There were some variations used in this simulation, first is the geometry of the tube, the first one was square and the other one was rectangle. The other variations are laser power, scanning speed, and scanning path (axial and circumferential). Based on the simulation, the highest bend value was 1.129 mm with 414 Mpa maximum stress was obtained from 1500 W laser power and 10 mm/s scanning speed with circumferential scanning path in rectangle pipe.
