Abstract

The invention provides a magnetic memory detection device for a cross manifold weld, used for detecting a weld (5) between a straight pipe (3) and an inclined pipe (4), wherein the magnetic memory detection device for the cross manifold weld comprises a magnetic memory sensor detection driving mechanism (1) and an assistant adjusting support (2), the magnetic memory sensor detection driving mechanism (1) comprises a detection unit (103) and a circular rail (115) capable of sleeving the outside of the inclined pipe (4), and the detection unit (103) can detect the detected weld (5) during the process of moving along the circular rail (115); the magnetic memory detection device for the cross manifold weld can perform omni-directional barrier-free detection on oblique crossing pipe intersecting line fillet welds with small angle areas. The error caused by manual operation during measuring can be greatly reduced, the smooth and stable detection process and accurate measuring result are ensured, and the measuring efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of non-destructive testing equipment for pipelines, in particular to a magnetic memory testing device for small-angle fillet welds of intersecting pipelines. Background technique [0002] Fillet welds are widely used in petrochemical, energy and electric power, railway bridges and other fields, especially in long-distance oil and gas pipelines, chemical pipelines, pressure vessels, flanges, valves, and row pipes in the petrochemical field. Since the stress state of fillet welds under pressure is relatively complex, and most single-sided welding is prone to incomplete penetration defects during manufacturing, it is extremely necessary to carry out timely and effective non-destructive testing and evaluation. [0003] However, conventional non-destructive testing methods are difficult to find defects in fillet welds, such as ultrasonic testing. For fillet welds, small pipe diameters, and thin pipe walls, it is difficult ...
