Abstract A novel technique of using activated flux in Tungsten inert gas (TIG) welding is used in the present investigations. The effect of hybrid multi-component surfactant (flux) is discussed in terms of depth of penetration (DOP), micro-hardness, tensile strength, and metallurgical traits. The activated TIG welding has been carried for different thickness of workpiece material with three factors current, travel speed, and flow rate at three levels. The results revealed a significant increase in the depth of penetration on using activated flux. The maximum DOP achieved is 8.283 mm with current 110 A, speed 82 mm/min and flow rate of 14 L/min. The results obtained from tensile test demonstrates that A-TIG welding produces welds with better strength. Radiography highlight defect-free welds on using activated flux. The outcomes of the present study confirm the applicability of this low-cost welding technique for joining SS-304 stainless steel thick sheets for the improved endowment.
