초록
This study focused on the effects of pulse current factors, such as peak current, base current, pulse frequency, and pulse length,on the mechanical and metallurgical characteristics of AA5754-H111 steel during gas tungsten arc welding. A total of eighteenconnections were created by correcting the above changes. The purpose of the current research is to examine the mechanicaland microstructural characteristics of welded joints. The optical microscope and SEM analysis were used to carry out themetallurgical characterization. The different types of welding parameter used and evaluated all the welded samples. Thecombination of 160A peak current, 75 Hz pulse frequency, and a 42% duration pulse results in the welded samples' superiormechanical properties as compared to other input welding conditions. These joints have advantages such as consistentlydistributed deposits, better fusion zone hardness, and increased grain quality in the weld zone. These characteristics assist toenhance the tensile characteristics present in joints.
