  • Method for determining characteristic stress of welding structure, method for designing welded structure, and method for manufacturing welded structure
    Patent number: 9931715
    Abstract: A test piece preparation step of preparing a test piece (50) including a welding structure in which a welding material formed of an austenitic alloy is welded to a member formed of low-alloy steel or low-carbon steel, a hydrogen supply step of supplying hydrogen to the test piece (50), and a characteristic stress acquisition step of applying a load (F) to the test piece (50) to which hydrogen was supplied and acquiring a characteristic stress showing material mechanical properties of the test piece (50) are executed.
