Abstract

The invention discloses a defect detection method, a device, a storage medium and a processor for T-shaped joint welds. Wherein, the method includes: detecting the thickness of the T-shaped joint workpiece to be detected; determining detection parameters for detecting defects in the T-shaped joint workpiece to be detected according to the thickness, wherein the detection parameters include at least phased array probe parameters and Detection angle: using the detection parameters to detect the defect of the weld seam of the T-shaped connection workpiece to be detected on the side of the branch pipe of the T-shaped connection workpiece to be detected. The invention solves the technical problem of relatively low defect detection rate.

Description

technical field [0001] The invention relates to the detection field, in particular to a defect detection method, device, storage medium and processor for T-shaped joint welds. Background technique [0002] The fillet weld of the pipe seat has a complex structure and groove type, and the thickness difference between the pipe seat and the main pipe is relatively large. During the welding process, due to the fast cooling of the fillet weld or the complex groove type, cracks, pores, incomplete penetration and incomplete The occurrence of defects such as fusion poses a certain threat to the quality of the weld. During the start, stop and operation of power plant boilers, the fillet welds of the pipe seat not only have to bear huge structural stress, but also bear the thermal stress caused by high temperature fluctuations and fluctuations in the operation process. The environment is complex and bad. Long-term operation of power plant boilers will cause the extension and expansio...
