Abstract

The electric current magnitude is a fundamental parameter that directly affects penetration characteristics and weld bead geometry. This study analyzes the effect of current variations on physical and mechanical properties in the cladding process using the Shielded Metal Arc Welding (SMAW) method. The materials used are low-carbon steel and HV-600 electrodes with a diameter of 3.2 mm. The SMAW method was applied with current variations of 100 A, 120 A, 140 A, and 160 A. The tests carried out were NDT liquid penetrant, macro structure, micro structure and Vickers hardness. The results indicate a positive correlation between increasing current and hardness values in the weld area, with the highest hardness recorded at 665.803 HVN at 160 A and the lowest at 515.143 HVN at 100 A. Meanwhile, in the Heat Affected Zone (HAZ), a non-linear pattern was observed, with a maximum hardness of 263.237 HVN at 120 A and a minimum of 219.110 HVN at 140 A. Microstructural analysis revealed the formation of ferrite, pearlite, bainite, and martensite phases in the weld area, providing insights into optimizing welding parameters to enhance the mechanical properties of low-carbon steel cladding.

Abstract

Alkali treatment using NaOH solution aims to to enhance the mechanical strength of the composite. This study investigates the effect of varying immersion durations of vetiver root fibers in a NaOH solution on the tensile strength of polyurethane-based composites. The vetiver fibers, serving as reinforcement, were cut to a length of 3 cm and immersed in a 5% NaOH solution for 2, 3, 4, and 5 hours, along with a control group without treatment. After soaking, the fibers were rinsed until reaching neutral pH and dried for three days. The composites were fabricated using the compression molding method under a pressure of 5 bar for 24 hours. Tensile tests were conducted following ASTM D638 standards. The results indicate that alkali treatment affected the surface characteristics of the fibers, including cleanliness and structural changes. The maximum tensile strength of 1.592 MPa was achieved with a 4-hour immersion, whereas the lowest tensile strength of 0.893 MPa was recorded after 5 hours of soaking.

Abstract

Corrective maintenance merupakan langkah perawatan yang dilakukan setelah terjadinya kerusakan, salah satunya pada komponen bogie pada Bucket Wheel Excavator (BWE). Kerusakan bogie dapat mengganggu sistem gerak dan menghentikan operasional alat berat secara keseluruhan. Penelitian ini bertujuan untuk mengidentifikasi penyebab kerusakan bogie dan menjelaskan tahapan perawatan korektif yang dilakukan. Metode yang digunakan meliputi observasi lapangan, inspeksi visual, pembongkaran, hingga pemasangan ulang bogie hasil reparasi. Hasil kegiatan menunjukkan bahwa keausan signifikan pada diameter luar roda bogie disebabkan oleh penggunaan material yang tidak sesuai standar pada proses perbaikan sebelumnya, seperti logam dengan tingkat kekerasan rendah yang mudah aus saat menanggung beban berat dan gesekan terus-menerus. Selain itu, pelumasan yang tidak memadai mempercepat keausan pada permukaan roda. Ketidaksesuaian tersebut menyebabkan gangguan pada kestabilan gerak bogie dan potensi kecelakaan kerja. Proses perawatan korektif yang dilakukan berhasil mengembalikan fungsi bogie secara normal. Temuan ini menegaskan pentingnya pemilihan material yang tepat dan pelumasan yang sesuai dalam mendukung keandalan dan keselamatan operasional alat berat di lingkungan tambang.

Abstract

The use of external magnetic fields is very influential in TIG (Tungsten Inert Gas) welding because it can disrupt the stability of the electric arc formed between the tungsten electrode and the base metal. Magnetic fields can cause the arc to distort or shift, resulting in uneven and low quality welds. TIG (Tungsten Inert Gas) is a welding method that uses a non-melting tungsten electrode to produce a weld. This study aims to determine the effect of external magnetic field on the quality of TIG welding results. This research uses the TIG (Tungsten Inert Gas) welding process on low carbon steel material with speed variations of 4 mm/s, 6 mm/s, 8 mm/s and 10 mm/s and uses 2 Neodymium type external magnetic fields. Tests carried out on the results of welding joints are Vickers hardness test, micro & macro structure test. The highest hardness test value was obtained in the 4 mm/s welding speed variation using 2 external magnetic fields with a hardness value of 187.388 HVN. Microstructure testing shows that the base metal contains ferrite and pearlite structures. In the HAZ (Heat Affected Zone) area there are ferrite, pearlite and martensite structures. Macro structure testing shows several welding defects, including porosity, imperfect penetration, underfill and irregular surface. The use of two external magnetic fields can affect the results of TIG welding itself, such as deepening the penetration of welding so as to produce a good welding joint. Some things you should pay attention to if you don't want welding defects to occur are paying attention to the distance between the electric arc and the material, and the torch must be parallel to the welding line.
