Abstract

In the steel structure fabrication industry, girders play a crucial role as supporting beams during construction. The girder's components include end plates and beams, with the end plate serving as a critical connection point for the beam to the column. Welding at this juncture demands careful consideration. This analytical research focuses on the impact of multiple repair welding and quenching temperatures during the heat straightening process on the toughness and microstructure of HSLA SM490YA material, utilizing FCAW welding. To assess the effects of multiple repair welding, the study compares different repair scenarios—welding without repair, two repairs, and three repairs, all performed at a 50% depth. Subsequently, the heat straightening process occurs at a temperature of 650ºC on the repaired material. Post-heat straightening, quenching is carried out with temperature variations of 650ºC, 475ºC, and 300ºC. The findings indicate that the repair process during welding and subsequent quenching after the heat straightening process leads to a decrease in toughness values. This results in a finer grain size, with the material phase predominantly composed of pearlite. These research outcomes should be carefully considered by industry professionals, particularly in critical connections, when determining quenching temperatures after the heat straightening process in repair procedures.

Abstract

The wrapping up and portray fabricating handle may be a organize of venture work at PT. Lintech Duta Pratama. Disgraceful portray forms result in absconds. Items that have absconds require repair so they can at that point be sent to clients. Rehashed repair forms cause expanded handle costs and obstruct item conveyance. In this manner, to get great item quality and diminish handle costs, inquire about to obtain ideal parameter settings is required. The method parameters considered are surface harshness, substrate temperature, and sort of abrasive fabric. The experimental design used is the taguchi method in the form of an orthogonal matrix . From the exploratory comes about, the ideal combination of handle parameters for prepare costs was gotten, to be specific surface harshness at level 1 with a esteem of 50 μm, temperature at level 2 with a esteem of 34 ° C, and rough fabric sort at level 2 with steel coarseness.

Abstract

Mesin TruPunch 5000 merupakan mesin pemotong dengan penggerak hidrolik yang menghasilkan tekanan hingga 1.600 langkah permenit, memiliki working area dengan ukuran 3050 mm x 1550 mm. Proses loading dan unloading pada mesin TruPunch 5000 menggunakan proses secara manual. Dimana untuk proses ini diperlukan 2 operator, 1 operator untuk melakukan proses loading dan unloading dan 1 operator untuk handle mesin pada saat pengambilan plat dari mesin agar kembali menyala. Sehingga penulis merancangkan alat bantu alternatif mesin loading-unloading yang diperlukan dalam pembuatan mesin agar mempercepat proses produksi. Metode perancangan yang digunakan adalah Metode Ulrich dengan membuat tiga konsep desain yang nantinya akan dipilih satu desain terbaik sesuai kriteria seleksi. Pembuatan desain dan analisis kekuatan struktur menggunakan Software Fusion 360 yang berbasis Finite Element Methods. Analisis kekuatan struktur mesin loading-unloading pada konsep terpilih didapatkan hasil dengan nilai tegangan (von mises stress) maksimum sebesar 80,9 MPa pada analisis software dengan batas tegangan izin material ASTM A36 sebesar 166,667 MPa. Kemudian didapatkan nilai safety factor sebesar 3, yang berarti struktur rangka mesin aman untuk digunakan.

Abstract

Vocational High Schools (SMK) have a strategic function in preparing graduates who are in line with the demands of the industrial world. However, approximately 55% of SMK graduates in Indonesia still do not achieve the expected competency standards, especially in the fields of digital technology-based engineering and manufacturing. One factor contributing to this condition is the limited mastery of 3D Computer-Aided Design (CAD) software, especially Autodesk Inventor. This activity is designed to improve the ability of SMK students in operating Autodesk Inventor through an intensive training program organized by the Design and Manufacturing Engineering Study Program of the Surabaya State Polytechnic of Shipping (PPNS) for students of SMK Negeri 5 Surabaya. The training program was attended by 85 students and was implemented using a participatory approach and Project-Based Learning. Assessment of learning outcomes was carried out through a comparison of pre-test and post-test scores analyzed using the Wilcoxon Signed-Rank test. The results of the analysis showed a significant increase in students' abilities in using Autodesk Inventor, as reflected in the difference in scores before and after the training. In general, this activity contributes positively to strengthening the technical skills of vocational school students while strengthening collaboration between universities and vocational schools in developing industrial technology-based competencies.ABSTRAKSekolah Menengah Kejuruan (SMK) memiliki fungsi strategis dalam menyiapkan lulusan yang selaras dengan tuntutan dunia industri.

Hasil analisis menunjukkan adanya peningkatan kemampuan siswa secara signifikan dalam penggunaan Autodesk Inventor, yang tercermin dari perbedaan skor sebelum dan sesudah pelatihan. Secara umum, kegiatan ini berkontribusi positif terhadap penguatan keterampilan teknis siswa SMK sekaligus mempererat kolaborasi antara perguruan tinggi dan sekolah kejuruan dalam pengembangan kompetensi berbasis teknologi industri.
