Positioning Fixture for Weld Detection
Technical Field The utility model belongs to the technical field of weld detection and particularly relates to a positioning fixture for weld detection.
Description of Related Art When steel bridge structures are prefabricated, different bridge sections need to be welded together in the bridge construction process due to the limitation of steel materials, and hence, welds are formed. Nowadays, welding of steel bridges, as one of the most important processes of the steel bridges, still have some problems such as incorrect weld sizes, incomplete penetration, cracks, welding beading, weld porosity, and breakage and deformation of welded parts. Flaw detection, also referred to as non-destructive testing, is a technology for checking whether there are any defects on metal surfaces and in welds. Common non-destructive testing technologies for internal weld defects include ultrasonic testing and radiographic testing, which are implemented by detectors by performing detection on weld surfaces with a flaw detection device. However, welds cannot be stably located by manual operations, and consequentially, the detection accuracy is unsatisfying.
Brief Summary of the Utility Model The technical issue primarily to be settled by the utility model is to provide a positioning fixture for weld detection. The positioning fixture is clamped on a detected part to allow a flaw detection probe to perform detection, and the distance between the flaw detection probe and a detected weld is ensured, so that the detection reliability is guaranteed.
