Abstract

Abstract TIG welding is a welding technique for connecting metals using tungsten rod electrodes and using noble gas as a protective gas which is exhaled on the weld metal to protect against contamination with the surrounding atmosphere. Aluminum metal is a metal that has a high affinity for absorbing H2, N2 and O2 in the air at high temperatures, so it is necessary to have a high purity protective gas during the welding process, because N2 H2 and O2 will cause a decrease in the corrosion resistance of the material. To find out the effect of the TIG welding process on the mechanical properties and microstructure, a study was carried out to determine the mechanical properties, namely hardness, and bending properties, as well as the microstructure found in aluminum after the tungsten inert gas welding process was carried out using current. different. In this study the welding process used the Tungsten Innert Gas process by varying the welding current, namely 100 A, 130 A and with a welding time of 2.5 seconds, 4.5 seconds, . So that from the welding parameters used, it will be known the effect of the welding parameters Keywords : Welding Current, Alumnium Metal, TIG welding

Abstract

Abstract The use of metal materials to support human life continues to grow along with the rapid development of science and technology. This greatly influences the technology to process it into a ready-to-use product. Among the production techniques used to make a product is the welding process. Welding is a method of joining that is widely used in steel building construction and machine construction. Another connection method used on metal joints is bolts and rivets. Welding technology, besides being able to be used to join and cut metal, can also be used to fill holes in castings, make hard coatings on tools, thicken worn parts, and other kinds of repairs. AISI 1037 is a carbon steel with a carbon content of around 0.37%, which is classified as Medium Carbon Steel. The tensile strength of AISI 1037 is 650 MPa with a yield stress of 350 MPa. A test has been carried out on AISI 1037 with the welding method, where the welding method used is the 1G and 1 F welding process. With this method compared to the mechanical properties of the welding results, the seam used is seam V with an E 6013 electrode with a diameter of 2.6mm. The welding process refers to the AWS D1.1 standard with the SMAW welding type with a plate thickness of 5mm.

Abstract

This study aims to determine the effect of variations in electric current in SMAW welding on tensile strength and microstructure. One of the factors that affect the strength of a material is the mechanical strength of the material properties. if the material is welded, it can affect the tensile strength and structure of the material. This research uses AISI 1080 steel material with a diameter of 1.24mm which contains C = 0.083%, Si = 0.21%, Mn = 0.5%, P = 0.008%, S = 0.007%, Cu = 0.03%, Cr = 0.03%, Ni = 0.02%, B = 0.013%, Alt = 0.025%, As = 0.06%, N = 0.0038%, and O = 0.1%. Specimens were welded with varying electric currents at intervals of 25mA, starting from 700mA, 725mA, 750mA, 775mA, and 800mA using the splicing method. The tensile strength results from flash butt welding with a current of 700mA were 853.6N/mm², at a current of 725mA it was 867.7N/mm², at a current of 750mA it was 847.4N/mm², at a current of 775mA it was 881.8mA, and at a current of 800mA it was 805.3mA.

Abstract

In its development, every manufacturing industry increasingly makes people think more creatively and are faced with new problems, especially in making new innovations. The purpose of these production issues is to achieve faster and more efficient production targets. The metal machining process is an important factor to support the quality of the final product, but there is one obstacle that must be faced.The main shaft is a component on hino truck vehicles, to produce components that are precise in terms of size and good surfaces are used for machining processes using a CNC machine, to simplify the manufacturing process, it is assisted by the Cam X5 master program to produce the G Code program to be used on the machine CNC. The manufacturing process uses a CNC Turning Machine.This research is an application of the CAD CAM course, the mastercam software application is very helpful in component manufacturing innovation. The main shaft is a form of a product resulting from the machining process, the material for the main shaft is made of AISI 1050 material

Abstract

Based on the results of research in Majalengka Regency, it was found that there were 200 semi-finished wood processing secondary industries, spread over 26 sub-districts with the type of wood used being dominated by teak, mahogany, these types of wood are used for semi-finished materials in the form of frames, doors, windows, cabinets, sideboard and chairs. There is also production of wood that is native to Indonesia, namely wood carving. Wood carving has its own uniqueness because it is a human creation based on an aesthetic sense according to what the human himself wants. Wood carving works of art are usually created using sculpting techniques. The creation of works of wood carving with the arrangement of elements so that meaningful elements are formed and one must have creative sculpting skills to produce works that are good, attractive and have meaning and high aesthetic value as well as being useful in people's lives.

Abstract

Biogas is one solution to overcome community difficulties due to rising fuel prices and the scarcity of LPG gas, this technology can be immediately applied, especially for cattle breeders. Utilizing cow dung that is processed anaerobically in a digester which will produce methane gas as an alternative energy. In planning this household-scale biogas device, there are several components designed including a digester with a volume capacity of 400L with a filling capacity of 2/3 of the digester volume, the material used is HDPE plastic (High Density Polyethylene) and a holding capacity of 147 L which produces a flash time. fire for 20.01 minutes for 15 days of the fermentation process. Where the lowest pressure is obtained on the 3rd day with a pressure of 104.668,73 N/m2, and the maximum pressure is on the 12th day with a maximum pressure of 107.201,85 N/m2i. simulation using solidwork software results in the digester construction which is planned to be used because it has a fairly good level of security

Abstract

In manufacturing companies, production activities are a very important activity. If the production activities produce a lot of defective products, it will cause losses in the form of additional time and raw material costs for repairing these defective products, so that quality control is needed so that the company can produce products that comply with predetermined quality standards. This final project research was conducted at PT. XYZ Majalengka where this company is engaged in the service industry, production activities at PT. XYZ Majalengka is carried out based on a make to order response demand strategy, namely the company carries out production activities when there are orders from consumers. This research focuses on the production process of the pirn winder machine which functions to wind yarn raw materials according to the desired weight and according to the available TFO capacity (700 gr, 714 gr, 1000gr or 1500gr). However, regardless of production quality standards on the pirn winder machine, it does not rule out the possibility that defects will always occur. Therefore it is necessary to have quality control in the production process of this pirn winder machine. Its function is clear to reduce the number of defects and improve the quality of production produced. Statistical Process Control (SPC) is a statistical analysis used for quality control, starting from monitoring, analyzing, predicting, controlling and improving the production process and product quality through control charts. Statistical quality control using SPC (Statistical Process Control) has seven statistical tools that can be used as tools to control quality, namely, check sheets, histograms, P control charts, pareto diagrams, cause and effect diagrams, scatter diagrams, and diagrams. process.
