Abstract

Welding is a technique that is widely used, such as in steel construction, the use of welding techniques can also save production costs. The extent of the use of this welding technique is due to buildings and machines that use jointing techniques to be lighter and simpler in the manufacturing process. TIG depends on the base metal to be welded. The filler rod is made of a metal whose composition is superior to that of the base metal. Because in the welding process there are some metal elements that are reduced or their structural transformations have an impact on reducing the mechanical properties of the metal. The purpose of this study was to determine the effect of filler on the microstructure of ASTM A36 steel welded joints and to determine the stress factor of safety on ASTM A36 steel using solid work software. The results obtained from the tensile testing process on the ER 70S -4 filler welding with an average strain of 2.2mm and a maximum tensile strength of 20.0 kg/mm2, and in the ER70S-6 filler welding the average tensile strain test results obtained 3 .1mm and an average maximum tensile strength of 28.1 kg/mm2. From the results of the Solidworks software simulation, it is known that the maximum tensile strength for specimens with filler ER 70S – 4 rods No. 1 is 21.71 Kg/mm2, rods No. 2 is 15.999 Kg/mm2, rods No. 3 is 22.12 Kg/mm2, for specimens with filler ER 70S – 6 rods No. 1 of 26.76 Kg/mm2, rods No. 2 of 36.63 Kg/mm2, rods No. 3 of 21.17 Kg/mm2 after calculating the error the maximum tensile strength test and simulation results obtained The biggest error value for ER 70S – 4 filler is 3.07% and for ER 70S – 6 filler is 2.97%. In this research, it can be found that ASTM A36 steel with ER 70S – 4 and ER 70S – 6 fillers is superior to using ER 70S – 6 filler from the higher tensile test results and the undoubted microstructure results in every part.

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
