Description

The application of field-welded butt joints of flanges and web plates for steel girder bridges has been on the increase in Japan. Figure 1 is an illustration of such a field-welded joint. The thickness of the flange plate may at times be in excess of 75 mm. Radiographic testing has been used to inspect the quality of welded joints in the shop; however, taking into account material having a thickness that is beyond the capacity of the radiographic testing and the risk of using X-rays in the field, ultrasonic testing is applied to field-welded joints [1,2].
