Purpose: The σ-phase is the most serious of these secondary phases due to its impact on the mechanical properties, corrosion resistance or weldability of stainless steels among other properties. The purpose of this study is getting free σ-phase welding joints by using very novel welding method such a called friction stir welding. Design/methodology/approach: Both of fusion welding methods (MIG and TIG) and friction stir welding method were used to compare microstructure analysis of AISI 430 ferritic stainless steels. After welding, the formation of σ-phase was investigated by mechanical, chemical and micro structure analyses of welded joints. Findings: As a result, the formation of σ-phase have not been observed in FSW processes while compared to traditional fusion welding processes. Not only σ-phase have not been observed in metallurgical investigations but also micro hardness of all specimen have not been over 400HV on friction stir welded joints. Research limitations/implications: It is very difficult to be constant vertical force during friction stir welding. For keeping constant this force, hydraulic controlled welding machines could be used in further researches. Practical implications: This paper and its’ results shown that the friction stir welding could be used for joining of ferritic stainless steels, when you select suitable welding parameters. Originality/value: This study was performed in the frame of the Pamukkale University Scientific Research Projects Coordination Unit project no 2009FBE022 “The research of the factors affecting the friction stir weldability of ferritic stainless steels”.
