Al2O3 and TiO2 flux enabling activated tungsten inert gas welding of 304 austenitic stainless steel plates

Gas tungsten arc welding (GTAW) is important in those manufacturing where it significant to control the mechanical and metallurgical characteristics its weld bead geometry. This work has been committed study influence of oxide fluxes on 4 mm thick 304 austenitic stainless steel plates. The Al2O3 TiO2 were used as an flux powder form are mixed with acetone. prepared mixture applied plate without any joint preparation filler wire addition. Taguchi method L9 orthogonal array determine optimal parameters. current aims explore parameters geometry (i.e. width, penetration angular distortion), & for welds. seems narrow thereby density increases at anode spot, that results high depth.
