Abstract
Pemotongan plasma cutting sering digunakan dalam dunia industri, dikarenakan proses ini lebih efektif dan efisien dalam penggunaannya maka dari itu pada proses pemotongan ini haruslah diperhatikan sifat-sifat benda dan cara-cara pemotongan berdasarkan fungsi dan tujuan.
Pada penelitian ini pemotongan menggunakan metode plasma cutting dengan variasi besarnya tekanan yang dipakai terhadap baja SUS 304. Variasi besarnya tekanan yang digunakan adalah 4 Bar, 5 Bar, dan 6 Bar. Kemudian diuji dengan pengujian kekasaran permukaan dan makro ETSA.
Pada pengamatan ini didapatkan tekanan terbaik sebesar 4 Bar dikarenakan mempunyai nilai kekasaran permukaan yang paling halus yaitu 9,96 m dan lebar HAZ yang paling kecil nilainya yaitu 1 mm. Untuk nilai kekasaran terbesar terdapat pada hasil pemotongan dengan tekanan 6 Bar yaitu 15,38 m dan lebar HAZ terbesar terdapat pada hasil pemotongan 5 Bar yaitu 3,7 mm.
================================================================================================
Plasma cutting is often used in the industrial world, because this process is more effective and efficient in its use so the cutting process must be considered in therms of properties and cutting methods base on function and purpose.
This observation is Plasma Cutting with pressure variation for steel SUS 304. The pressure variation are 4 Bar, 5 Bar and 6 Bar, and then uses toughness testings and metallopraphy by using a way called macro ETSA.
In this observation, the best pressure is 4 Bar because it has the smoothest surface roughness value of 9,96 m and the smallest HAZ width is 1mm. For the largest rougness value found in the cutting result with a pressure of 6 Bar, which is 15,38 m and the largest width of HAZ is found in the result of cutting 5 Bar which is 3,7 mm
