Description

Ultrasonic inspection method has been recently developed to be applicable to gas pressure welding of reinforcing bars. The practicability of this method was tested in such a way at several construction sites as to apply to over 16000 points of pressure welded bars. And for 370 pressure welded points, both ultrasonic inspection and tension tests were performed. The results are encouraging and it can be concluded that the ultrasonic inspection is very useful not only to find out defect of bars but also to grade up generally the quality of pressure welding. Personal deviation of measurements has been examined and a draft of judging criteria has been obtained
