Analysis of Welding Current Variation Effects on Gas Metal Arc Welding (GMAW) Characteristics in Low-Carbon Steel

Journal of Educational Engineering and Environment
This research utilizes Gas Metal Arc Welding (GMAW), a process whose performance characteristics significantly influence weld strength, particularly tensile capacity and flexibility. Higher electrical control contributes to increased tensile strength in welds, sometimes exceeding the base metal's tensile strength.
