Abstract: This study aims to elucidate the impact of welding methods on the hardness and tensile properties of weld joints. Findings revealed that double pass welding significantly increased hardness in the weld zone compared to single pass welding. This difference is attributed to the rapid heating and cooling in single pass welding, resulting in lower hardness values. The additional pass in double pass welding enhanced the hardness by promoting better mixing and homogenization of the filler material with the base metal. Single pass heat affected zone (HAZ) showed variable hardness, increasing with distance from the centerline due to different thermal exposures. Double pass HAZ, when subjected to two heat cycles, experienced more extensive thermal exposure. The additional filler material in double pass welding improved ultimate tensile strength and yield strength by 20% and 15%, respectively. These results highlight the significant impact of double pass welding on both hardness and tensile strength.
