| Abstract: |
| The authors took the lead in studying the low temperature(-40℃) fatigue property (S-N curve) of welded joint of HSLA steel, HQ80C, thus providing a scientific basis for engineering design and so also the welded structure safety. The test results were modeled and forecasted by applying. the Grey System Theory for guiding the test process and improving test precision. |
| Key words: welded joint low temperature fatigue property grey forecast |
