Abstract: In accordance with GB/T 2358-94, CTOD (crack-tip opening diaplacement) tests were conducted at 650℃ for electron beam welded joints of GH4169 alloy. According to the requirements of the standard, the specimen was a standard SE(B) (three point bending), the results were calculated using the P-V curves of parent material and weld metal. Finally, the test results were summarized and analysed.
