Structure and Mechanical Properties of 1.4539 Austenic Steel Joints Made by TIG and Laser-Beam Welding
This paper presents the analysis of structural research, micro-hardness and fatigue properties of the base material which is 1.4539 steel and joints made with CO2 laser beam and TIG method. Theoretical and experimental analysis of low cycle fatigue based on deformation criterion was presented. Safe fatigue estimation consistent with the results of experiments was obtained during calculations.
