Embodiment Construction
[0067] Further description will be given below in conjunction with the accompanying drawings and preferred embodiments of the present invention.
[0068] Such as figure 1 , figure 2 As shown, a single-sided, double-sided, multi-angle ultrasonic testing method for welded seams of heterogeneous structural types includes the following steps:
[0069] Step (1): In the simulation software, establish a 3D model of the pipeline to be tested with flange or elbow welds and two multi-angle ultrasonic probes, which are respectively the simulated pipeline to be tested and the simulated ultrasonic probe;
[0070] Step (2): In the simulation software, place two simulated ultrasonic probes on both sides of the simulated weld, respectively, and make the two simulated ultrasonic probes simulate sector scanning;
[0071] Step (3): Move the two simulated ultrasonic probes back and forth until the simulated sound beams of the two simulated ultrasonic probes can completely cover the simulated w...
