Abstract

The invention relates to the technical field of weld joint detection, in particular to a flaw detection device of a round pipe type steel member. The detection device comprises a substrate for carrying a round pipe type steel member; a base is mounted on the substrate; a positioning ring sleeved to the outside of the round pipe type steel member is arranged on the base; a detecting ring coaxiallydisposed with the positioning ring is installed on the positioning ring in a rotating manner; and an ultrasonic probe and a scribing device that slide radially relative to the detecting ring and are abutted against the outer surface of the round pipe type steel member are installed at the detecting ring. According to the detection device, while the weld joint position is detected, the boundary ofthe weld joint can be marked accurately, so that the efficiency of the weld joint detection is improved effectively.

Description

technical field [0001] The invention relates to the technical field of weld seam detection, in particular to a flaw detection device for circular tubular steel components. Background technique [0002] The steel component system has comprehensive advantages such as light weight, factory manufacturing, fast installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution. With the unique advantages of the development in three aspects, steel components have been reasonably and widely used in the field of construction engineering on a global scale, especially in developed countries and regions. In order to make the quality of steel components meet the requirements, the quality of steel components needs to be tested before leaving the factory. [0003] The existing publication number is CN108459079A, which is a circular tubular steel component flaw detection device, which includes a conveyor belt, an arc groove for pl...
