Abstract

The purpose of this study is to examine metal inert gas (MIG) and tungsten inert gas (TIG) welding processes. This study focuses on welding defects with various kinds of AISI- 1020 mild steel welding joints when using metal inert gas (MIG) and tungsten inert gas (TIG). The impact of different process variables on mild steel welding was looked into. In this study, the main process parameters were changed, and destructive tests (tensile test) were used to examine the impact on hardness and impact strength. Yield stress, elastic stress, breaking stress, and breaking force were all measured during a tensile test. Additionally, non-destructive (NDT) testing was done. Non-destructive testing was used for the liquid penetration and ultrasonic tests. The necessity of exceptional weld quality was also highlighted by a comparison of the two testing methods. The tensile test results for MIG welding are displayed in Fig. 12 and are 204.793 N/mm2 for yield, 27688 N/mm2 for elastic behavior, and 180 N/mm2 for breaking behavior. For MIG welding, the welding link was broken at 180 N/mm2. Figure 13 shows the TIG welding stresses as 313.633 N/mm2 for yield, 16506.2 N/mm2 for elastic, and 257.890

N/mm2 for breaking. At 257.890 N/mm2, the welding connection failed. AISI-1020 mild steel had a breaking stress of 420 N/mm2 prior to welding. Following welding, the breaking stress decreased to 257.890 N/mm2. Shielded metal arc welding, gas metal arc welding, flux cored arc welding, submerged arc welding, electro slag welding, electron beam welding, and gas tungsten arc welding are just a few of the various welding techniques available for joining materials. The type of current, the thickness of the base materials, and the compositional range of the

material to be welded are the main factors that influence the choice of welding. The most widely used gas shielding arc welding technique in many industrial domains is TIG welding. The most crucial factors in determining arc stability, arc penetration, and defect-free welds are covered in this case study, including the power source, type of current, gas flow rate, electrodes, filer wire, TIG machine settings, and shielding gases.
