Abstract

The invention relates to a method and a device for determining an intersecting line scanning central angle for pipe welding. The device comprises a traveling arc length acquisition module, a proportional coefficient acquisition module and a central angle acquisition module, wherein the traveling arc length acquisition module is used for acquiring an intersecting line traveling arc length in an intersecting line scanning process; the proportional coefficient acquisition module is used for comparing the intersecting line traveling arc length with a preset total intersecting line arc length to obtain a proportional coefficient; the central angle acquisition module is used for acquiring the scanning central angle according to the proportional coefficient; the scanning central angle is obtained by multiplying the proportional coefficient with 360 degrees. Therefore, according to the method and the device for determining the intersecting line scanning central angle for pipe welding, the proportional relation between the traveling arc length during intersecting line scanning and the total arc length of an intersecting line is converted into the scanning central angle, so that the intersecting line scanning central angle can be determined in real time, and the reliability of an ultrasonic flaw detection result is improved.

Description

technical field [0001] The invention relates to the technical field of ultrasonic flaw detection, in particular to a method and a device for determining the central angle of the scanning circle of intersecting lines for welding of pipe fittings. Background technique [0002] As we all know, the flaw detection of intersecting line welds of pipe fittings has always been the most difficult part in the ultrasonic flaw detection process. The weld cross section of the intersecting line weld of pipe fittings is different in each place. The width and relative depth of the weld will change at any time with the change of position, and in order to keep the ultrasonic beam perpendicular to the weld at the current position at each flaw detection position , it is necessary to adjust the appropriate probe detection angle at any time. In addition, different cross-sections at different positions, relative depths, multiple wave reflections, etc. will cause great difficulties in the positioni...
