The utility model discloses an ultrasonic reference test block for detecting a welding seam of a same steel fillet at a pipeline pressure measuring point. The ultrasonic reference test block comprises a simulated pipeline barrel and a simulated pressure measuring point connecting pipe, the simulation pipeline cylinder is welded with the simulation pressure measuring point connecting pipe to form a connecting pipe seat fillet weld, the root incomplete penetration artificial defect and the groove incomplete fusion artificial defect are arranged in the connecting pipe seat fillet weld, and the reference block can be used for detecting the internal defects of the same steel fillet weld of four large pipeline pressure measuring point connecting pipe seats. And the combined performance of the ultrasonic detector and the probe can be verified, the detection sensitivity can be adjusted, and the defect size and position can be determined. 本实用新型公开了一种用于管道压力测点同种钢角焊缝检测的超声对比试块，包括模拟管道筒体及模拟压力测点接管；模拟管道筒体与模拟压力测点接管相焊接，以形成接管座角焊缝
