Weld joint of aircraft landing gear bear the major alternating stress and impact stress
which often lead to fatigue cracks. According to the feature of landing gear damage and comparison of various detection methods
the ultrasonic phased array inspection method is chosen
and the reference block is made as the test piece. Ultrasonic phased array inspection can effectively detect the fatigue crack in weld joint through modeling and testing
and the problems that should be solved in practical detection by experiment are pointed out.
