Welding is widely used for construction of many structures. Effect of welding on dynamic characteristics and reliability has not been clear. Inthis paper, effect of welding on the damping ratio and the natural frequency is examined by experiment. By using many specimens of same size, thedamping ratio and the natural frequency are estimated. It is concluded that the damping ratio of welded specimen is larger than that of base metal.The natural frequency of welded specimen is almost same as that of base metal. Next, effect of welding on reliability of structure is examined forwhite noise excitation. For first excursion problem, reliability of welded specimen is higher than that of base metal.
