摘要： The present invention relates to a semi-automatic scanner for ultrasonic inspection of a branch pipe weld that has a small size and is able to perform an inspection while moving in a state of being attached to a test object by a magnetic force, thereby being applied to fittings having various shapes, such as a branch pipe and an elbow. The semi-automatic scanner for ultrasonic inspection according to the present invention includes a probe configured to inspect a weld by irradiating ultrasonic waves onto a surface of a test object, a probe holder configured to couple the probe by applying an elastic force so as to be pressed against the surface of the test object, an installation bracket having a rod shape, to which the probe holder is coupled so as to be laterally movable, four wheel units installed on both front and rear side surfaces of the installation bracket so as to be vertically slidable, and four magnet parts, each of which is installed on one of the four wheel units and presses the one of the wheel units against the test object with a magnetic force.

摘要： The present invention relates to a scanner having a flexible probe which is an apparatus capable of being utilized for an inspection on a weld zone of a general ferrite material and a stainless material and allowing an inspection to be performed on a fitting weld zone where it is difficult for a general phased array ultrasonic testing (PAUT) probe to approach. A scanner having a flexible probe according to the present invention includes a probe fixing body (110) which moves while coming into contact with a surface of a bent fitting pipe and to which a probe body (101) is fixed, a flexible connecting chain part (120) installed to be connected to one end of the probe fixing body (110) and having a freely bendable structure, a sensor installation part (130) installed on an end of the flexible connecting chain part (120) and configured to move while pressed against the surface of the fitting pipe, a sensor (140) which is connected to the probe body (101) in a flexible state and of which an end is installed on the sensor installation part (130) and scans a weld zone of the fitting pipe, and an encoder part (150) installed to be connected at one side of the probe fixing body (110) and configured to move while pressed against the fitting pipe and detect a moving distance and a position.
