INVESTIGATING THE EFFECT OF WELDING CONDITIONS ON THE TENSILE STRENGTH OF GMAW JOINTS

Abstract

This study investigates the impact of various welding conditions on the tensile strength of joints produced using Gas Metal Arc Welding (GMAW). The tensile strength is a critical parameter in evaluating the mechanical performance and durability of welded structures. Different welding parameters, including voltage, current, welding speed, and filler material, were systematically varied to assess their effect on the tensile strength of the welded joints. The experimental procedure involved creating a series of welds on mild steel specimens, followed by tensile testing to determine the strength of the welds. The results demonstrated a significant relationship between welding conditions and the tensile strength, with certain parameter combinations leading to enhanced joint performance. Additionally, the study analyzed the microstructure of the welds to correlate the mechanical properties with the microstructural changes. The findings provide valuable insights into optimizing welding parameters for achieving strong and reliable welds in industrial applications.
