Microstructural features of Aisi 430 Ferritic Stainless Steel (FSS) Weld Produced under varying process parameter

Microstructural features of Aisi 430 Ferritic Stainless Steel (FSS) Weld Produced under varying process parameter

the microstructural features of the weld section which are controlled by the energy input and heat transfer factors. The welding current, travel speed and the material property govern these parameters. However, the specific influence of range of heat input rates on the microstructural features of FS...
