  • Resistance test method
    Patent number: 7409869
    Abstract: A method for evaluating thermal fatigue resistance for a welding consumable alloy can include the following steps: placing a test specimen of a welding consumable alloy in a testing device such that a tensile load and a compressive load can be introduced to the test specimen; heating the test specimen to a first temperature; applying a compressive force to the test specimen while heating the test specimen; cooling the test specimen to a second temperature; and applying a tensile force to the test specimen while cooling the test specimen.
