This study employed a combination of experimental and numerical approaches to examine the effects of welding heat on fabricated mild steel gates. The study utilized AISI A36 Mild Steel plates as the material for the samples. These samples, both welded and unwelded, were prepared from plates with thicknesses of 2 mm, 3 mm, and 4 mm, featuring a width of 13 mm and a carbon content of 0.25 percent. Tensile tests were conducted using a Standard Universal Tensile Test Machine. Numerical simulation of the thermal distribution during welding, was done using ANSYS. The findings indicated that all tested samples exhibited fractures within the Heat Affected Zone (HAZ) and around the welded joints. Furthermore, the mechanical properties of the welded samples demonstrated a decrease in values, except for tensile strength, which exhibited an increase. This increase was attributed to grain recrystallization due to intense welding heat near the welded area.
