Jan 01, 2020 · Trichy, Tamilnadu- 620015, India Abstract In this work, an attempt was made to conduct bead on plate welding of NiTinol Shape memory alloy utilizing Yb:YAG laser welding process and identify the optimized parameters using Dengâs Similarity based Hybrid Intelligence Modeling using Genetic Algorithm for To obtain the desired weld bead geometry, HAZ width and make a good weld, it becomes important to set the welding process parameters. Since the experimental optimization of these parameters is time consuming, soft-computing techniques are commonly used for optimization of the welding process parameters (welding voltage, current and torch speed).

Modified 9Cr-1Mo steel is used as the structural material for steam generator components of power plants. Activated tungsten inert gas (A-TIG) welding is increasingly used for fabricating these components. With the aim to achieve maximum depth of penetration (DOP) and minimum heat affected zone (HAZ) width, computational methodologies were adopted for optimisation of A-TIG welding process.
