영문 초록

Mild steel (SS400), which has excellent workability and strength, is typically used in the production of various structures, vessels, chemical plants, and machinery tools in industry. An excellent welding unit should be flawless and highly efficient at all types of position welding. Following welding, a structure should have excellent mechanical properties and be crack resistant. Tungsten inert gas (TIG) welding processes are divided into manual welding in which material and torch are manually manipulated by a welder, semi-automatic welding in which material is fed into a machine but where the torch is manually operated, and automatic welding in which both material and torch are operated by machines during the entire welding process. This study aims to compare and analyze the penetration shape variations based on electrode tip angles and shield gas changes during TIG welding. An experiment was conducted that showed that both the penetration shape and electrode angle changed when gas was used. In addition, the chemical components related to corrosion resistance were reduced, whereas those related to hardness were found to increase. Based on the results of this analysis, a more in-depth study should be conducted regarding the application of the processing method of electrodes when using gas.
