IRSM 41 is a corrosion-resistant steel widely employed in railway wagons. In the present study, IRSM 41 steel plates of 8 mm thickness were joined using conventional TIG welding (C-TIG) and activated tungsten inert gas welding (A-TIG). Three multicomponent fluxes were utilised during the A-TIG welding. The application of fluxes enhanced the depth of penetration and reduced the bead width. Weldments produced with flux 3 have a thorough penetration of 8 mm in a single weld pass. Bead geometry has been analysed through various aspects such as bead width, depth of penetration and depth-to-width ratio. Metallographic examination and Hardness study of C-TIG and A-TIG weldments was performed. The average fusion zone hardness was found to be better in A-TIG weldments than in C-TIG weldments. The obtained weldments bead geometry and properties have been discussed in contrast of various input parameters.
