Abstract

Power source is a device that serves to supply electrical current in type of welding SMAW (Shield Metal Arc Welding), an example is DC-400 machine. The output current of machine is set using a knob on the output control panel in order to generate heat as needed welding. Along with the development, welder realized that there are limitations in the way of controlling current on the machine. Distance control that requires users to go directly to the machine caused inefficiency in work. Therefore, we need a controller for adjusting the output current from long distance. It is necessary to create "Current Control Device for DC-400 Machine Based Microcontroller and Android". This device can adjust the output current value from long distance and wireless which is a microcontroller as the central controller and android as the input source. From the results of research, the greater value of R1 in potentiometer is set, the greater welding current is generated. The average error between the welding current using the knob and remote is 4.65%.

Abstract

High residual stress can occur in stainless steel and carbon steel weld joints due to difference of thermal expansion coefficients. Corrosion-resistant and mechanical properties of weld joint is affected by stainless steel sensitization, resulted by chromium carbide precipitation, and carbon diffusion on heat-affected zone. This study is conducted to investigate post-weld heat treatment effects of stainless steel 316 and AISI 1018 weld joint with 309L filler metal. As the post-weld heat treatment temperature rises between 400 and 700°C, the hardness value decreases. Observed microstructure of heat-affected zone shows dominance of ferrite phase which experiencing grain growth.

Abstract

SKD 11 steel is a tool steel which is often applied in the manufacturing industry, such as cutting, punching, stamping tools, shear blades, dies and others. And in it’s application, of course steel must have a hard structure, strong and touhgness affected due to external forces causing deformation or change in shape. To improve the quality, heat treatment is required on the steel by providing austenizing, quenching and tempering temperature variations 400 °C, 550 °C and 650 °C. Which purpose to determine the hardness and microstructure of the tempering variation results. The first step of cutting material SKD 11 steel, followed by austenizing process up to 1050 °C and then quenching process (fast cooling) with medium water and continue the process of tempering variation 400 °C, 550 °C and 650 °C. After the heat treatment was complete, take hardness test and view the microstructure of the SKD 11 steel. At temperatures tempering 400 °C showed the highest hardness value of 56.5 HRC, followed by tempering temperatures 550 °C at 52.9 HRC and the lowest occurred at temperature tempering 650 °C at 39.1 HRC. Microstructure formed pearlite and martensite. Then the higher temperature tempering then the declining value of steel hardness SKD 11.

Abstract

Corrosion is a problem that always occurs in metals in their application to the environment. Although there are already several other substitute materials such as polymers and composites, the use of metals is still very much needed and plays an important role, especially in the oil and gas fabrication industry. Corrosion cannot be avoided but can be minimized because of the nature of the metal that will return to its origin. Metals used in the oil and gas fabrication industry require a material test against stress factors and the environment. The SSCC (Sulphide Stress Corrosion Cracking) test based on NACE TM0316 is a test of material resistance to stress and acidic environments. In this SSCC test, the method used is Four-Point Bending, which means that there are four roller jigs to bend the specimen. The specimens used are API 5L X65 pipe welded joint specimens and ASTM A694 flange. The welding process on this specimen uses the GTAW (Gas Tungsten Arc Welding) process. The specimens tested have several stages, starting from the preparation of the machined material, cleaning, then bending to soaking in an acidic liquid. This aims to determine the indications that appear on the surface of the specimen in the form of cracks in both the weld and the base metal. The test used three specimens with different IPRR welding processes. Specimens 1 and 3 are accepted specimens, while specimen 2 is rejected specimens based on the SSCC DNV Test Procedure, where the acceptance criteria from the MPI results are acceptable if the indication is less than 1 mm in length.

Abstract

Welder qualification is the qualification of a welder or welder that aims to prove the quality of the welder, which is carried out following the rules in international codes/standards such as AWS, API, ASME, ISO, and other codes/ codes/standards. The purpose of this report is to design a welder qualification scheme using three codes/standards at once, namely: AWS D1.1 (2020), ASME Sec. IX (2019) and ISO 9609-1 (2017). Thus, it can minimize costs, time, and the preparation needed to qualify the welder. The methodology used was a literature review to get the similarity of the variables, which will later be used to qualify the welder using the three codes/standards used. After obtaining the required variables, the next step was the implementation of these variables to qualify the welder from the material preparation and welding process to test the weld results. In order to qualify the welder with three codes/standards at once, it was necessary to pay attention to the relationship for each variable used to cover one code with another. If one of the variables cannot be met in one of the codes/standards used, then the welder's qualification using three codes/standards cannot be implemented. The material used in this welder qualification is ASTM A106 Grade B with a material length of 170 mm × 170 mm with a thickness of 18.26 mm and a diameter of 6" (168.3 mm) sch 160. The test methods used were Visual Inspection and Side Bend Test with four samples.

Abstract

Power BI merupakan salah satu software intelligence buatan Microsoft yang digunakan untuk mengolah serta memvisualisasikan data dan menampilkannya dengan grafis yang lebih interakif serta variatif dalam bentuk dashboard. Beberapa keunggulan Power BI ini ialah bersifat Share Data, Real Time Dashboard, dan dapat mengolah data original yang jumlahnya melebihi kapasitas aplikasi lainnya. Dashboard pada Power BI akan digunakan untuk mengolah data Non-Conformance Material. Data Non-Conformance Material adalah data yang mencakup keseluruhan informasi dari kumpulan aktual material yang menyimpang dari standar atau ketentuan yang sudah ditetapkan dan dikategorikan ke dalam beberapa Defect Type. Material yang memiliki defect akan dikarantina untuk sementara waktu sampai mendapatkan disposisi yang telah disepakati pada saat Material Review Committee (MRC) Meeting. MRC Meeting merupakan pertemuan dari perwakilan masing-masing departemen untuk menentukan disposisi terhadap material Non-Conformance. Maka dari itu, penggunaan Power BI untuk representasikan data Non-Conformance Material sangat bermanfaat dikarenakan salah satu keunggulannya yaitu dashboard Power BI sendiri bersifat Live Data yang artinya ketika mengubah atau menambahkan sesuatu di Master File, dashboard Power BI akan berubah secara otomatis mengikuti Master File tersebut. Hal ini tentu saja dapat mempermudah visual yang tampak rumit bagi pengguna maupun audience yang melihat.

Abstract

NDT means testing without damaging the material or specimen. One of the NDT equipment that can be used to measure the thickness of the hull plate is the Ultrasonic Thickness Gauge (UTG). This tool uses sound waves that are reflected and received by the probe and converted to numerical data, the number is used to see the thickness of the plate material. The research purpose is identifying the thickness of tanker Tyche hull plate by Ultrasonic Thickness Gauge (UTG). Based on data from the Tyche hull shell opening table on the portside and sideboard the smallest test results are 9.7 mm. These results are still included in the tolerance because if the initial plate thickness is calculated from 12 mm – 2.4 mm, then the minimum acceptable thickness is 9.6 mm. If it is found that the plate thickness is below 9.6 mm based on the standards from the Indonesian Classification Bureau (BKI), the plate will be declared NG (Not Good) and the replating process will be carried out. Based on the test table, no UTG results were found which were below the standard plate thickness that had been set. Therefore, the Tyche tanker with the IMO code 8794891 is still feasible to operating and there is no need for a partial or complete replating process.

Abstract

The working principle of CNC Milling machine is the machine rotates and contacts with the workpiece so that erosion and cutting occur. The machining process affects the mechanical properties of the material, so it needs to conduct a study to determine changes in the character of the material due to the machining process. This research was conducted to determine the effect of the number of 2 flutes and 4 flutes on the workpiece surface roughness using PMC-5VT20 CNC Milling machine. Specimens test use 304 material stainless steel that has strength and resistance to the corrosive. The research method was carried out experimentally using 304 stainless steel material which had been done with a finishing process using an endmill cutter with 2 flutes and 4 flutes. The roughness of specimens were tested using surface roughness tester to determain the effect of flute number on the surface roughness. The result of testing shows that the number of flutes affects the roughness of the machining process. The roughness value using 2 flutes is lower than the use of 4 flutes.
