【 摘 要 】

The current research work is based on combine effect of TIG & MIG welding to achieve desirable mechanical properties. The stainless steel 304L plates were selected for welding. Current, Voltage and gas flow rate were taken as input parameters to study the response (hardness and width of weld bead). The experiments were conducted with the help of a full factorial design. The increase in gas flow rate decreases the hardness of the weld bead as well as increases the bead width to some extent. Non-dominated Sorting Genetic Algorithm was used to optimize the responses. Sixteen non-dominated solutions were obtained. The welding current, voltage and gas flow rate should be maintained at approximately 200A, 24V and 15-17 l/min respectively for the best hardness and bead width value.
