Abstract

A common issue encountered with main heat exchanger equipment is improper operation, which can lead to the development of cracks in the stainless-steel pipes. The welding process alters the metal microstructure in the heat-affected zone, thereby affecting the mechanical properties of the welded joint. To mitigate this issue, TIG welding with argon shielding gas is employed. This method helps prevent oxidation and ensures the formation of a stable welding arc in 304 stainless steel, which is renowned for its excellent mechanical properties and corrosion resistance. The objective of this study is to evaluate the impact of variations in shielding gas flow on the mechanical properties of 304 stainless steel plates during the TIG welding process. The aim is to determine the optimal settings for producing robust and long-lasting welded joints. To assess the hardness of the welded joints, we employed a Brinell-type Hardness Tester FB-3000LC machine. A Brinell steel ball indenter measuring 5 mm on the HBW scale and applying a load of 125 Kgf was utilized. At a protective gas flow rate of 8 L/min, the average tensile stress was 44.72 N/mm², strain was 0.177, modulus of elasticity was 2518 MPa, and hardness was 99.712 HBW. Increasing the gas flow rate to 13 L/min resulted in an average tensile stress of 47.50 N/mm², strain of 0.189, elastic modulus of 2525 MPa, and hardness of 105.522 HBW. Further increasing the gas flow rate to 18 L/min led to an average tensile stress of 49.69 N/mm², strain of 0.192, modulus of elasticity of 2597 MPa, and hardness of 106.704 HBW. Based on the research findings, it was observed that the weld area exhibited an increase in hardness values due to the heat generated during the welding process. The use of protective gas flow during welding is deemed effective in producing well-formed welded joints, as it prevents fractures from occurring within the weld area during the tensile test process. The choice of protective gas is determined by the dimensions of the material plate.

Abstract

Salah satu penyebab fraktur pada tulang ialah kecelakan pada saat beraktifitas maupun berkendara. Penggunaan pelat implan metatarsophalangeal (MTP) menjadi satu dari berbagai macam metode penanganan fraktur pada tulang. Maka penting untuk mengetahui kemampuan pelat implan dalam menahan segala jenis pembebanan yang mungkin terjadi saat digunakan di tubuh manusia. metode yang digunakan untuk menganalisis kekuatan struktur pelat implan MTP ini adalah dengan menggunakan finite element method. Terdapat tiga tahapan dalam metode ini. Tahapan pertama adalah preprocessing, jenis material dan jenis meshing ditentukan pada tahapan ini. Lalu tahap solution, yaitu penentuan jenis pembebanan dan constraint  yang digunakan. Terakhir tahapan post processing, yaitu proses analisis hasil simulasi yang dilakukan pada dua tahapan sebelumnya. Pada penelitian ini didapatkan nilai von-mises stress dengan pembebanan 44.228 N hingga 200 N sebesar 51.492 MPa hingga 232.85 MPa. Nilai tersebut masih berada di bawah nilai tegangan luluh material Ti-6Al-4V yakni sebesar 880 MPa. Nilai von-mises stress yang rendah tersebut mengakibatkan deformasi total dan deformasi sumbu Z yang terjadi cukup rendah, rata-rata pada angka 0.0189 mm dan 8,77x10-4 mm. Berdasarkan perolehan nilai tersebut dapat disimpulkan pelat implan MTP dengan material Ti-6Al-4V tidak terjadi deformasi plastis. Deformasi yang terjadi pada  pelat implan MTP adalah deformasi elastis, dengan nilai yang cukup rendah. Sehingga aman digunakan sebagai salah satu alat bantu dalam proses penyembuhan fraktur pada tulang MTP.

Abstract

The development of production techniques is required to produce good products that have standards for the products produced, both in terms of profile shape, size precision, surface roughness, hardness, material flexibility, and others that comply with standards. The surface roughness of a product can affect its functions, such as its level of precision and ability to accept loads. This research aims to find out how much influence cutting speed and depth of cut have on surface roughness with variations in cutting speed parameters of 21 meters/minute and 26 meters/minute and for AISI 4140 steel cutting speed parameters of 12 meters/minute and 17 meters/minute and cutting depths of 0.1 mm and 0.3 mm on four types of steel with End Mill cutting blades made from High-Speed Steel with a total of 4 flute cutting blades. Next, surface roughness testing and analysis of variance were carried out to determine the influence of parameters on surface roughness. The results obtained were that the largest average surface roughness, namely Ra = 5.33 µm, occurred on AISI 4140 steel at a cutting speed of 12 m/min with a cutting depth of 0.3 mm. Meanwhile, the smallest average surface roughness, namely Ra = 0.91 µm, occurred on AISI 1045 steel at a cutting speed of 21 m/min with a cutting depth of 0.1 mm. Next, an analysis of the variance method was also carried out with the following results: cutting speed only affected S45C steel because the value of Fcount>Ftable (13.18107506 > 5.32). The depth of cut does not have a significant effect on surface roughness on all types of steel because of the comparison results Fcount<Ftable. The interaction of cutting speed and cutting depth does not affect surface roughness because the comparison shows that Fcount <Ftable for all types of steel.

Abstract

Pemanfaatan serat daun nanas masih tergolong sedikit hanya dimanfaatkan sebagai bahan dasar berbagai jenis produk furniture, kain untuk produk fasion, kerajinan dan komposit sebagai material pembentuk. Penelitian ini bertujuan untuk menganalisis kekuatan Tarik komposit serat daun nanas dengan variasi fraksi volume menggunakan resin poliyester bening. Dalam penelitian ini dilakukan pembuatan komposit dengan menggunakan tiga fraksi volume yang berbeda yaitu 60% serat : 40% resin, 70% serat : 30% resin, dan 85% serat : 15% resin. Setelah proses pembuatan spesimen pengujian, kemudian spesimen dilakukan pengujian uji tarik pada setiap fraksi volume. Hasil penelitian ini menunjukkan adanya variasi kekuatan tarik pada setiap fraksi volume yang digunakan, yang mana dengan menggunakan fraksi volume 85% serat : 15% resin menghasilkan kekuatan tarik yang lebih tinggi dibandingkan dengan fraksi volume 60% serat : 40% resin dan 70% serat : 30% resin. Komposit yang diperkuat serat daun nanas dengan variasi fraksi volume serat daun nanas 60% : resin 40%, serat daun nanas 70% : resin 30%, dan serat daun nanas 85% : resin 15%. Dari variasi persentase tersebut yang memiliki kekuatan tarik tertinggi pada serat daun nanas 85% : resin 15% dengan nilai rata-rata sebesar 105,694 MPa, kekuatan modulus elastisitas 1576 MPa, dan elongation yaitu 6,74%. Sedangkan nilai kekuatan tarik terendah terdapat pada serat daun nanas 60% : resin 40% , dengan nilai rata-rata sebesar 74,30 MPa,kekuatan modulus elastisitas 1231 MPa, dan elongationi 6,04%, maka dapat disimpulkan bahwa semakin banyak persentase serat maka semakin tinggi nilai kekuatan tarik. Variasi fraksi volume serat daun nanas dapat mempengaruhi sifat mekanik komposit resin polyester bening. Nilai kekuatan komposit naik sering bertambahnya fraksi volume serat. Namun fraksi volume serat yang tinggi tidak selalu memberikan pengaruh yang baik terhadap kekuatan komposit. Kekuatan komposit tidak hanya dipengaruhi oleh jumlah serat tetapi juga dipengaruhi oleh faktor pengikat yaitu matrik.
