Abstract

This study aims to determine the effect of welding current on the mechanical properties and microstructure of gray cast iron welding joints using nickel electrodes with the SMAW welding process. The research method used was experimental study, starting with preparing the workpiece, welding process, making test specimens and testing the weld specimens. The material to be joined is gray cast iron metal with a butt joint of a 60 ° open seam V open angle. The welding process used uses SMAW with a current of 80 Amperes, 85 Amperes and 90 Amperes. The added material used was an ENiFe-Cl type CIN 2 electrode with a diameter of 2.6 mm. Hardness testing was carried out using the Vickers method and microstructure testing using an optical microscope. The results showed that the maximum hardness value of the parent metal occurred at the welding current strength of 85 Amperes, which was 192.17 VHN, then the maximum hardness value of the HAZ area occurred at the welding current strength of 85 Amperes, which was 203.46 VHN, while the maximumhardness value of the weld metal was 203.46 VHN. metal) occurred at a welding current of 90 Amperes, which was 211.18 VHN. The results of the microstructure observation showed that the matrix formed on the parent metal was pearlite withgraphite in the form of flakes. The micro structure formed in the HAZ area was a martensite structure. Meanwhile, the microstructure of weld metal consists of an austenite matrix with an even distribution of graphite particles.

Abstract

Industri kelapa sawit yang di kenal sebagai tandan kosong kelapa sawit. Saat ini perkembangan teknologi bahan semakin pesat. Berbagai bahan telah penelitian berlanjut untuk mendapatkan matrial yang lebih baik, yaitu matrial komposit. Tujuan penelitian dapat mengetahui pengaruh fraksi volume serat tandan kosong kelapa sawit dengan sifat mekanik, jenis patahan dan mencari komposisi fraksi volume yang terbaik. Metode penelitian yang di gunakan pencetakan penekanan fraski volume 4%, 6% dan 8% pengujian di lakukan kampus Politeknik Negeri Pontianak Kampus Kab. Sanggau. Penelitian telah mendapatkan hasil, dengan bertambahnya fraksi volume serat maka nilai kekuatan tarik yang di miliki spesimen fraksi volume serat 4%,6%, dan 8%  43.20 MPa, 65.00MPa, dan 86.12MPa. Nilai regangan masing-masing pada fraksi volume 4%, 6%, dan 8% yaitu 11.80%, 4.07% dan 4.68%  dan tanpa serat 6.47% adanya pengaruh regangan komposit berpenguat serat TKSS yakni pada fraksi volume 4% yakni 11.80%. Komposit bepenguat serat tandan kosong kelapa sawit bisa di jadikan penguat pada komposit. Jenis patahan yang terjadi pada spesimen resin polyster dan komposit berpenguat serat TKKS jenis patahan getas. Fraksi volume serat 6% yang di miliki modulus elastistas terbesar dengan nilai 21,04 MPa. Hasil ini mempengaruhi fraski volume serat 4% dan 8% 2.66% , dan 21.48% sedangkan tanpa serat tandan kosong kelapa sawit 8.79MPa.Kata kunci: Resin Polyster, Komposit, Serat tandan kosong kelapa Sawit, UJi tarik
