                      Abstract: The hot wall hydrogenation reactor operates under harsh conditions such as high temperature, high pressure, and
                   hydrogen corrosion for a long time, and defect detection of the inner wall cladding layer is crucial for equipment safety. A multi-
                   mode fully focused imaging detection method based on mirror echo estimation is proposed to address the technical difficulties of
                   ultrasonic testing on the outer side of the hydrogenation reactor weld layer. Firstly, a mirror echo estimator is used for simulation
                   analysis to obtain the sensitivity of the multi-mode fully focused imaging area, and to determine the ultrasonic path sensitive to
                   defects in the weld overlay; Then, obtain the fully focused imaging features of crack defects under different paths; Finally, the
                   multi-mode fully focused imaging method is used to detect and locate crack defects of different sizes on the surface of the test block
                   weld layer. The simulation and experimental results have verified the reliability of this method in detecting inner wall cracks and
                   locating defects accurately, providing a more economical and efficient detection solution for the industry.
