This study by Ankur Bansod investigates the effect of different filler materials used in welded joints of 430 ferritic stainless steel (FSS) formed by the Tungsten Inert Gas (TIG) welding method. The TIG welding method is commonly preferred for ferritic stainless steel due to its ability to produce high-quality, clean, and precise welds.

Research Details:

This study analyzes the effects of 310 (austenitic) and 410 (ferritic) filler materials on the welded joints.

Microstructural Findings:

The 310 filler material led to a columnar microstructure in the weld.

The 410 filler material caused the formation of a ferritic (acicular ferrite) microstructure, along with martensite and austenite phases.

Mechanical Properties:

Weld samples with 410 filler material exhibited superior mechanical properties compared to those with 310 filler material.

Significant effects of filler material were observed in microhardness, chromium-nickel equivalent ratio, and tensile strength.

These findings emphasize the importance of selecting the appropriate filler material to achieve the desired microstructural and mechanical properties in weld joints.
