Abstract

The invention relates to an apparatus for examining welded joint dimension and cylindrical shell circularity, and belongs to the filed of pressure vessels and boiler examining equipment. The apparatus includes a rack body with a calibrated scale. The rack body has a middle part serving as a mounting area and two ends serving as telescopic areas. The center of the rack body is provided with a distance measuring apparatus. The rack body is provided with a sliding reference block through a fastening bolt on one side of the distance measuring apparatus. The distance measuring apparatus is externally connected to a calculator for calculating the difference between a distance between the center of the rack body and a measuring point from a set value or a reference value. The invention has the beneficial effects of: direction determination of conformity between joint corner angles, erroneous variables and cylindrical shell circularity and standards and rules through aligning the distance measuring apparatus with a point to be tested, reading a distance value before uploading the distance value to the calculator, calculating by a computer built-in program, automatically obtaining the difference and displaying the difference; the apparatus has a reasonable entire structure design, simple and easy operation, high efficient measuring efficiency, and low measuring cost.

Description

technical field [0001] The invention relates to an inspection instrument which can be applied to inspect whether the size of the welded joint of the pressure vessel and the boiler and the roundness of the cylinder conform to the inspection standard, and especially relates to a welding apparatus suitable for inspecting the circumferential edge angle and circumferential misalignment of the welded joint The utility model relates to an inspection instrument for joint size and cylinder roundness, which belongs to the field of pressure vessel and boiler inspection equipment. Background technique [0002] At present, according to the provisions of GB150-2011 "Pressure Vessels", the method for inspecting the circumferential edges and corners of welded joints of pressure vessels is to use a chord length equal to D i / 6, and not less than 300mm inner template (or outer template) inspection. GB150-2011 "Pressure Vessels" also stipulates that the roundness can be measured by the inner ...
