Title

WELDING OF 304L STAINLESS STEEL WITH ACTIVATED TUNGSTEN INERT GAS PROCESS (A-TIG)

Pages

  27-33

Abstract

 Gas tungsten arc welding is a popular process in those applications requiring a high degree of quality and accuracy. However, this process has a big disadvantage against the substantially high productivity welding procedures. Hence, many efforts have been made to improve its productivity. One of these efforts is the use of activating flux (A-TIG WELDING). In this study, the performance of A-TIG WELDING on 304L austenitic STAINLESS STEEL plates has been presented. Two OXIDE FLUXes, TiO2 and SiO2 were used to investigate the effect of A-TIG WELDING process on weld morphology, microstructure and mechanical properties of weldments. The experimental results indicated that A-TIG WELDING could increase the weld penetration and depth-to-wide ratio. It was also found that A-TIG WELDING could increase the DELTA-FERRITE content of weld metals and improve the mechanical properties. Moreover, a 2D axial symmetric model was developed to simulate the flow behavior in the melting pool. These results were compared to those experiments carried out on a STAINLESS STEEL (304L) melted by a stationary heat source.
