Study of hardness properties of butt welded joints using Metal Inert Gas (MIG) welding on mild steel plate / Muhammad Syahir Azman

Mild steel is one of the materials that is commonly utilised in many sectors due to its good mechanical qualities, but can this mild steel be used in welding with metal inert gas. An investigation was made on the welding procedure on mild steel plates employing metal inert gas. The butt kind of connection was employed for this investigation. After welding, mild steel plates undergo a hardness test using a Vickers hardness machine to determine their degree of hardness. On welded mild steel plates, dye penetration tests were also carried out. Any faults that could be present on the plate will be found using this test's outcome as its benchmark. The findings demonstrate that when mild steel plate is welded utilising metal inert gas welding, its hardness value improves.
