Abstract:

Fatigue life of BT20 Titanium alloy sheet and its laser beam welded joints was evaluated experimentally. The mean fatigue life of the joints, under various stress levels, was obtained. The lower band life of lease beam welded joints, with a survival probability of 99% and a confidence level of 95%, was also obtained. The effect of welding condition on the fatigue life of the joints was analyzed. It was found that the fatigue life of the joints, either welded by conventional leaser beam or by active leaser beam, is lower than that of the base metal.
