Abstract

The brake system is one of the engine component elements in a vehicle that can support the comfort and safety factor in driving. Brakes work to slow down or slow down the movement of the wheels by means of problems. Kinetic energy lost from a moving object is usually converted into heat due to an effect. The purpose of this report is to know the canvas life, function, working principle and efficient calculation. The method used to make reports from direct observations of objects, literature studies and guidance from supervisors. From the specifications of the drum brakes that have been described, we can find out the calculation steps needed to find the normal force on the rear wheel, the permissible frictional force on the asphalt, the life of the canvas with ceramic material, and the maximum spring force at the top and bottom. After several calculation steps, the normal force on the rear wheel will be 2270.50 N. The permissible frictional force on the asphalt is 681.10 N. The service life of the canvas with 100 days of braking for 1.40 seconds is 45 days. The maximum force of the upper spring is 24.99 N, and the maximum force of the lower spring is 166.62 N.

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

AbstractCurrently, metal joining techniques in the field of welding have developed rapidly. In constructions that use metal raw materials, most of the joints are made by welding. Apart from joining, the welding process can also be used for repairs, for example to fill holes in castings, make coatings on tools, thicken worn parts and other repairs. Welding is also widely used for building construction, bridges, piping and automotive. As we know, there are many types of welding used today. One of them is Gas Tungsten Arc Welding (GTAW) or commonly called Tungsten Inert Gas (TIG).AISI 1045 steel is referred to as carbon steel because it complies with international coding, namely the 10xx series based on the nomenclature issued by AISI and SAE (Society of Automotive Engineers). The first number 10 is the code that indicates plain carbon, then the code xxx after the number 10 indicates the carbon composition. So AISI 1045 steel means carbon steel or plain carbon steel which has a carbon composition of 0.45%. Steel of this specification is widely used as a component of gears, shafts and bearings. According to its function, it must be able to withstand wear and tear due to friction with the chain. Wear resistance is defined as resistance to abrasion or resistance to dimension reduction due to friction
