The low-cycle fatigue tests for TIG welding (tungsten inert gas arc welding) samples of GH4169 alloy were carried out. The special clamp for the thin samples was designed to eliminate the side-deformation during test loading. The results of curve, fatigue life and fatigue strength of the TIG welding joints were acquired by fitting the test data.
