Abstract

The invention relates to a pipe welding opening detector and belongs to the technical felid of welding equipment. The pipe welding opening detector comprises an admission piece 1, a barometer 2, a sealing strip 3, a detector shell 4, a screw clamp 5, and a detector shell joint 6. The admission piece 1 and the barometer 2 are arranged on the detector shell 4. The detector shell 4 is in the shape of a semi-circle. The sealing strip 3 is arranged inside the detector shell 4. The screw clamp 5 is arranged on the outer edge of the detector shell 4. The detector shell joint 6 is used for connecting two detector shells 4. The middle of the detector shell 4 is arc-shaped. In use, two edges are respectively fixedly arranged on two pipelines which are welded together. The arc in the middle of the detector shell 4 is directed at the welding opening of the two pipelines.

Description

technical field [0001] The invention relates to the technical field of welding equipment, and relates to a pipeline welding joint detector. Background technique [0002] The invention mainly aims at the difficulty that some small cracks cannot be detected whether the part to be welded is completely welded or not when the pipeline is welded, and invents a pipeline welded joint detector. Contents of the invention [0003] The invention is a pipe welding joint detector which uses air to detect whether there are cracks in the pipe welding joint, and can solve the above-mentioned problems. [0004] The invention is composed of an air inlet nozzle, an air pressure gauge, a sealing strip, a detector casing, a screw clamp, and a joint of the detector casing. The air inlet nozzle and the barometer are installed on the detector shell, which is semicircular, the sealing strip is installed on the inner side of the detector shell, the screw clip is installed on the outer edge of the d...
