摘要： PURPOSE:To easily record the results of flaw detection by mounting a recorder which electrically takes out the outputs corresponding to the varying sizes of large, medium or small defects and operates based on the signals thereof to a wave transmitting probe in a manner as to move cooperatively with the probe. CONSTITUTION:A wave transmitting probe 1 and a receiving probe 2 are moved equidistantly in mutually opposite directions from a ground line, whereby the entire area of a weld zone C is detected for flaws. The electric signals from the transmitting probe and the receiving probe are inputted to an ultrasonic flaw detector 3, which detects the size of the flaws of the weld zone based on said signal and lights defect display lamps 3A-3C. A recorder 4 for the results of the flaw detection is provided with a pen supporting table 5 which moves cooperatively with the probes. The table 5 supports a purality of pens 7A-7C which display by segmenting the degrees of the defects of the weld zone. The pens 7A-7C are operated by the output signals corresponding to the degrees of the defects of the weld zone from the ultrasonic flaw detector and record the positions and degrees of the defects on recording paper 10.

摘要： PURPOSE:To make it possible to judge a defective echo only from the echo level resulting from only one longitudinal scanning operation by providing a flaw detecting element for generating ultrasonic beam and by a flaw detecting element for receiving the same and by moving and scanning them at the same speed on the body sides of a mother material by means of a jig. CONSTITUTION:In case the welded portion C between a column A and a beam B is to be inspected the center shaft 6 of a link mechanism 3 is fixed in position on the mother material by means of a magnet. A transmitting flaw detecting element 1 and a receiving flaw detecting element 2 are attached to the stationary shafts 4 and 5 of the link and connected with a flaw recorder 13. An element moving device 17 is fixed to the both sides of the mother material by means of a magnet so that a wheel 20 is made to mesh with a gear 16. If a synchronous motor 14 fixed to the mother material by a magnet 15 is turned the elements 1 and 2 are moved at an equal speed in the opposite directions so that the echoes reflected from the welded portion C following that movement are recorded. A defective echo diagram is attained in accordance with the level so that the defective echo can be judged only from its level by the once longitudinal scanning operation.

摘要： PURPOSE:To perform the flow detection of the weldered parts simply and correctly, by using two probes. CONSTITUTION:At the fixed axes 6 and 8 placed at the tip of the links 3a to 3f fixed to the center shaft of the surface plate 1, the transmission probe 5 having the same width as the thickness of the beam flange B and transmitting ultrasonic beam toward the boundary T, and the reception probe 7 receiving the ultrasonic beam reflected on the boundary T with the same constitution are placed. Further, while the probes 5 and 7 are moved with equal distance toward opposite direction each other along the side surface of the beam flange B, ultrasonic waves are propagated in the steel member through the contact medium such as glycerin. The all the surface of the welded part C is checked for cracks, the height to deficient echo is detected, the changes in the height and the integration value are compared with value for the comparing test piece to estimate the deficient area at the welded part C.

摘要： PURPOSE:To maintain a reinforcing effect, a stress transmission effect and a concrete filling effect by joining a steel girder having a closed section and a steel girder using a reinforcing hardware circumscribing the steel column and a joining material directly joined to the hardware. CONSTITUTION:A steel column 1 having a closed section is circumscribed with a belt-like reinforcing hardware 3 formed by joining four unit hardwares 3o separated in the middle portion of a flange of the steel column 1 to each other. Further, a joining hardware 4 is disposed extending over two unit hardwares 3o adjacent to each other and joined by bolts 6. Steel girders 2 having a closed section are joined to the joining hardwares 4. A bracket may be used instead of the joining hardware 4. A reinforcing effect, a stress transmission effect and a concrete filling effect which the reinforcing hardware 3 has can be maintained without any influence on the steel column 1 by welding in a sound joining condition.
