Aimed at the location and guidance problems of X-rays automatic inspection equipment in tube-tube sheet (TTS) welding, this paper presents a method for detecting central coordinates of girth welds based on inverse compositional AAM with a triaxial flaw detection device for tubular heat exchanger. The method includes the design of software framework, calibration algorithm, center detection algorithm, etc. Using the proposed center detection algorithm, the accuracy is verified with experimental data.
