Nashrullah, Muhammad Faiq (2019) Pengaruh Plunge Depth dan Heating Time Terhadap Kekuatan Geser Struktur Al-HDPE Dengan Metode Friction Spot Welding Menggunakan Clamping Frame AISI 304 dan Kayu Jati. Sarjana thesis, Universitas Brawijaya.
Abstract
Paduan aluminium dan High Density Polyethylene (HDPE) digunakan dalam berbagai aplikasi khususnya dalam bidang industri manufaktur karena memiliki keunggulan antara lain: berat yang ringan, ketahanan korosi yang baik, kuat, dan fleksibilitas desain. Penelitian ini bertujuan mengetahui kekuatan geser struktur Al-HDPE. Metode penyambungan yang digunakan yaitu friction spot welding yang merupakan metode penyambungan alternatif berbasis pengelasan. Penelitian ini dilakukan dengan menvariasikan plunge depth (1,5 mm dan 2 mm), heating time (10 detik, 20 detik, 30 detik, dan 60 detik), serta material clamping frame (AISI 304 dan kayu jati). Perlakuan permukaan aluminium dilakukan dengan proses grinding untuk meningkatkan kekasaran permukaan sehingga kekuatan geser akan meningkat. Uji kekuatan geser dilakukan sesuai standar ASTM D3163-01. Hasil penelitian menunjukkan bahwa kekuatan geser struktur Al-HDPE mengalami peningkatan pada heating time 10 detik sampai 20 detik kemudian cenderung menurung sampai heating time 60 detik. Berdasarkan analisis melalui foto makro pada heating time 10 detik panas yang diserap HDPE masih rendah sehingga lelehan pada HDPE sedikit yang mengakibatkan kekuatan geser rendah dan pada heating time >20 detik mengalami penurunan kekuatan dikarenakan kelebihan panas yang diserap. Kekuatan geser tinggi juga didapat pada plunge depth 2 mm dikarenakan pembentukan nub semakin terlihat jelas yang menyebabkan terjadinya makro mechanical interlocking.
English Abstract
Aluminum alloy and High Density Polyethylene (HDPE) are used in various applications specifically in the manufacturing industry because they have advantages such as: light weight, good corrosion resistance, strong, and design flexibility. This study aims to determine the shear strength of the Al-HDPE structure. The joining method used is friction spot welding which is a method of joining alternative based welding. This research was conducted by varying the plunge depth (1.5 mm and 2 mm), heating time (10 seconds, 20 seconds, 30 seconds, and 60 seconds), and clamping frame material (AISI 304 and teak wood). Aluminum surface treatment is carried out by grinding process to increase surface roughness so that shear strength will increase. The shear strength test was carried out according to ASTM D3163-01 standard. The results showed that the shear strength of the Al-HDPE structure experienced an increase in the heating time of 10 seconds to 20 seconds and then tended to decreased to 60 seconds heating time. Based on the analysis through macro photos on heating time of 10 seconds heat absorbed by HDPE is still low so that melt in HDPE is a little which results in low shear strength and at heating time> 20 seconds has decreased strength due to excess heat absorbed. High shear strength was also obtained at a 2 mm plunge depth because the formation of the nub was increasingly apparent which caused macro mechanical interlocking.
