Study of hardness propeties of butt welded joints using Metal Inert Gas (MIG) welding on stainless steel plate / Muhammad Izzat Hakimi Rosli

This proposal focused on hardness properties off butt welded joints using Metal Inert Gas (MIG) welding on stainless steel plate. MIG welding is one of the well -known welding techniques nowadays but is this type of MIG welding strong and hard. In addition, are there any porosity defects to the samples welded using MIG welding. Therefore, this research paper will continue the study to find out whether this type of MIG welding is suitable for welding stainless steel and whether there are any porosity defects after the welding is done. in this study, the stainless-steel plate will be welded using MIG type welding with butt joint type. Vickers hardness machine will be used to determine the hardness value of the sample that has been welded. Dye penetration test will be used in this study to detect whether there are any defects involving the porosity of the sample that has been welded.
