Abstract

Welding is the process of joints metals by melting through heating. Interpass temperature can influence the rapid slowing of the cooling rate and also determine the percentage of accicular ferrite formation, the slower cooling rate will form more accicular ferrite. Accicular ferrite is a structure that is expected from every welding process because it has more resilient properties. This study aims to determine the effect of temperature interpas on the mechanical properties of the welding process SMAW SS400 carbon steel material. Welding specimens were given variations in interpas temperature treatment namely 100oC, 150oC, and 200oC. The results showed that interpas temperature variation could affect the tensile strength value of welded material. The voltage value on the 100oC interpas specimen is 38.26 Kgf / mm2. The value of the stress in the 150oC interpas specimen is 39.09 Kgf / mm2. The value of the stress in the 200oC specimen is 37.37 Kgf / mm2. The value of the stress without treatment is 32.21 Kgf / mm2. Keywords: Welding, SS400 Carbon Steel, Tensile Test, Interpass TemperatureAbstrak Pengelasan merupakan proses penyambungan logam dengan cara pencairan melalui pemanasan.

Abstract

Aluminium is a material that is now widely used for welding because this material has good mechanical properties, is corrosion resistant, is light in weight and can be recycled. The problem that occurs in aluminium welding is the presence of a passive layer or layer of Al2O3 oxide which has a high affinity for oxygen. This oxide layer is also an insulator which can inhibit the flow of current in welding. The amount of current in the welding process greatly affects the amount of heat input, weld concentration and arc stress. The purpose of this study was to determine changes in the mechanical properties of tensile strength and hardness of welded metal joints with variations in welding current on aluminium Al-6061 using the TIG welding process. The stages of the research method carried out were to carry out the TIG welding process on aluminium material joints with variations in currents of 120A, 140A and 160A. The filler rods used were AWS A5.10/ER-5356 and argon gas with a flow volume of 15 l/m. Furthermore, the results of the weld are tested for tensile and hardness to determine changes in the mechanical properties of the weld joint. The results show that the magnitude of the welding current affects the strength of the welding joint in terms of mechanical properties, especially the value of the tensile strength and hardness of the material when receiving loads and also affects the strain or elongation of a material. The highest tensile strength value is at a current strength of 160A of 9.83 Kgf/mm2, while the lowest tensile strength value is welding using a current strength of 120A with a value of 9.73 Kgf/mm2. The most ductile or ductile welded joints are welding using a current of 120A. While the highest hardness value was in the 160A weld metal area of 95.17 HRE and the lowest was in the HAZ area of 160A current of 41.17 HRE

Abstract

Gas Tungsten Arc Welding (GTAW) adalah suatu proses pengelasan dengan menggunakan gas mulia sebagai pelindung. Untuk menghasilkan busur listrik, digunakan elektroda yang tidak terkonsumsi terbuat dari logam tungsten atau paduannya yang memiliki titik lebur tinggi. Baja tahan karat austenite 304 atau yang sering disebut stainless steel 304 merupakan baja paduan dengan kandungan Cr 18-20%, dan Ni 8-10,5%. Baja jenis ini biasa digunakan sebagai bahan kontruksi utama dalam beberapa industri seperti nuklir, kimia, dan makanan. Baja ini memiliki ketahanan terhadap korosi yang baik karena terdapat lapisan kromium oksida pada permukaannya. SS304 merupakan baja yang memiliki tingkat kekerasan rendah sekitar 123 HB dan kekuatan tarik sebesar 505 N/mm². Penelitian ini bertujuan untuk mengetahui kekuatan tarik hasil pengelasan GTAW pada baja tahan karat SS304 dengan variasi sudut kampuh bevel. Dari pengujian yang telah dilakukan, diketahui bahwa kekuatan tarik tertinggi terdapat pada material tanpa penyambungan dengan nilai rata- rata kekuatan tarik 63.84 kgf/mm², sedangkan pada material yang dilas kekuatan tertinggi terdapat pada kampuh bevel dengan sudut 40° dengan nilai rata- rata 55.30 kgf/mm°, sedangkan kekuatan tarik terendah terdapat pada kampuh bevel dengan sudut 35° dengan rata- rata kekuatan tarik 50.68 kgf/mm².Kata kunci :  Pengelasan GTAW, stainless steel 304, kekuatan tarik, elektroda EWTH-2, kampuh. Effect of groove variations on the tensile strength of the material Stainless Steel 304 AbstractGas Tungsten Arc Welding (GTAW) is a welding process using argon gas as a shield. To produce electric arcs, non-consumed electrodes made of tungsten metal or alloys that have a high melting point. Stainless steel 304 is an alloy steel with 18-20% Cr content, and Ni 8-10.5%. This type of steel is commonly used as the main construction material in several industries such as nuclear, chemical, and food. This steel has good corrosion resistance because there is a layer of chromium oxide on its surface. SS304 is a steel that has a low hardness level of about 123 HB and tensile strength of 505 N / mm². This study aims to determine the tensile strength of GTAW welding results in SS304 stainless steel with a variation of the groove angle. From the tests that have been carried out, it is known that the highest tensile strength is in the material without connection with an average tensile strength value of 63.84 kgf / mm², while in the material welded the highest strength is in the bevel groove with an angle of 40 ° with an average value of 55.30 kgf / mm °, while the lowest tensile strength is in the bevel groove with an angle of 35 ° with an average tensile strength of 50.68 kgf / mm².

Abstract

Inspection of 900 angle pipe welds using the Radiography method with an Ir.192 source with a capacity of 150 Curie while operating 56 curies using the Double Wall Double Image Technique Case study at (PT. Sinar Mas, Riau). Errors and inaccuracies in timing result in the resulting image being damaged, not meeting radiographic film acceptance quality standards. irradiation (exposure time). The purpose of this paper is to be able to calculate the exposure time using computation, and to know the type of defects in the welding and there are significant undercutting defects that require repair or re-welding and are declared rejected by the radiographer. The results of the exposure time calculation between the calculations of several processes have a relatively large time difference, this is because they do not follow the curve value. In the end it can be concluded from the results of the film is very influential on the exposure time. Based on this, the resulting software can be declared in accordance with field conditions

Abstract

Electrodes for the Manual Metal Arc (MMA) welding process or welding electrodes are classified based on the type of coating which is informed by the last digit code of the electrode. Electrodes E7016 and E7018 are basic types of electrodes with a Low Hydrogen Potassium coating type which are widely used in welding heavy construction equipment and piping. This electrode has a minimum tensile value of 70 ksi (480 MPa) with a carbon content of 0.07% for E7018 and 0.08% for E7016. The difference in carbon content in the composition of the electrode will determine the hardness value of the resulting weld. In use in the field these two electrodes are often recommended and can even be exchanged according to the assumption that the minimum tensile value is relatively the same between the two electrodes. However, due to the difference in carbon content, it will affect the hardness of the weld (weld metal) after welding. Many studies have been carried out to determine the mechanical properties of the welded joints using these electrodes, but research on the specific mechanical properties of the welds of the two electrodes is very rarely carried out. The test method is carried out by making 2 test specimens each for currents of 80A, 100A, and 120A using E7016 and E7018 electrodes with a diameter of 3.2mm. The material used is SA.36. The hardness test was carried out using the Rockwell-C (HRC) method. The test results show that the hardness value of the basic low hydrogen potassium electrode E7018 has a higher hardness value than E7016 for the same current. At currents of 80A, 100A, and 120A, there was an increase in the hardness of the E7018 weld metal against E7016 by 2.0% each; 9.8%; and 6.7%. The highest hardness value is found at 80A of 42.3HRC for the E7018 electrode, and 41.5 HRC for the E7016 electrode. In E7016 the increase in current causes a decrease in hardness level of 8.2% from 80A to 100A; 12.3% from 100A to 120A. In E7018 the increase in current causes a 1.2% decrease in hardness from 80A to 100A; 14.7% from 100A to 120A

Abstract

Joint materials using welding require the correct stages, starting from the design stage to the processing stage. The design stage starts from the selection of the type of welding, to the selection of the seam angle used. Meanwhile, at the processing stage, the current strength will be selected according to the processing position. The purpose of this study was to determine the effect of welding heat input on the mechanical strength of SS-400 steel in SMAW welding. In this study the material used was SS-400 with current variations of 90 A and 100 A. The results showed that the welding current affected the tensile strength and toughness of the material. The welding current of 100 A has the highest tensile strength and toughness, and then 90 A which has the lowest tensile strength and toughness, while the strain that occurs at current 90A is 13.53%, and the strain that occurs at current 100 A is 12.07%.

Abstract

The drilling process commonly employs API 5CT pipes, one type of which is API 5CT Casing Pipe Grade L80 Type-1. Long casing pipes are generally connected using the Threaded and Coupled (male-female) method. In certain conditions, welding is used for joining, and the combination welding process GTAW-SMAW is commonly employed in the field. The electrodes used are generally ER-70S-G (GTAW) and E7010-P1 (SMAW). The E7010-P1 electrode is difficult to obtain in the field. It is not only expensive but also scarce. Therefore, in some cases, construction contractors often substitute the E7010-P1 electrode with E7016, which is more readily available. This substitution is based on the consideration that both electrodes have similar tensile strength values (70ksi). This study aims to determine the mechanical properties of the joint process of API 5CT Casing Pipe Grade L80 Type-1 using E7016 electrodes and to evaluate the feasibility of substituting it for the E7010-P1 electrode. NDT testing was performed using a penetrant test, while DT testing was carried out using Vickers Hardness testing. The hardness test results showed that the highest average hardness value was found in the material using the E7016 electrode, which was 304 HVN, specifically in the weld metal area. Based on these results, E7016 can be recommended as a substitute for the E7010-P1 electrode.
