The effects of different Ar/H2/N2 plasma gas mixtures on the performance of stainless steel plasma cutting has been investigated experimentally using a plasma arc cutting torch working at 400A. Results of the microstructural and compositional analysis of the kerf surface using SEM - EDS show that the presence of N2 or Air in the plasma arc column can affect the chemical composition and microstructural characteristics of the kerf surface, influencing machinability and weldability.

Abstract

The effects of different Ar/H2/N2 plasma gas mixtures on the performance of stainless steel plasma cutting has been investigated experimentally using a plasma arc cutting torch working at 400A. Results of the microstructural and compositional analysis of the kerf surface using SEM - EDS show that the presence of N2 or Air in the plasma arc column can affect the chemical composition and microstructural characteristics of the kerf surface, influencing machinability and weldability.
