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.
