Abstract
Welding is the science of metal joining, usually performed on similar metals. In the current study, Nd-YAG laser welding system was used for joining two different categories of steel (Mild Steel and SS-304), expected to have different properties. Dissimilar joints play a crucial role in the current industrial situation where multiple materials are used for everyday tasks. DOE was used to optimize the system input parameters. Quality of a weld is determined by the aspect ratio (depth of weld/width of weld), which was determined using metallography. Microhardness test was also inducted to study the hardness of these welds. A relationship was determined between microhardness, quality of weld and input parameters using Grey Relational Analysis (GRA) methodology.
