Abstract :
We studied the characteristics of 316LN welded joints produced by different welding fillers through temperature and field dependent magnetization measurements. The magnetic permeability of welded joints showed significant variations depending on the used welding fillers. Qualitative changes from 316LN base material were observed in the field dependent magnetization of welded specimens. While the self-welded and low-Mn content filler-welded samples showed signs of secondary phase formation, considerable suppression of the secondary phase formation was observed in high-Mn content filler-welded samples. The austenitic-structure-retaining property was also observed in the FE-SEM microstructure.
