7. The automatic scanning device of the ultrasonic phased array of pipe seat fillet welds according to claim 1, wherein the number of the magnetic wheels (14) is four, and the four magnetic wheels (14) are respectively positioned at four corners of the base (12).
8. The automatic scanning device of the tube seat fillet weld ultrasonic phased array according to claim 1, wherein an included angle range of the main tube (1) and the branch tube (13) is 0 ° < θ <180 °, and θ is an included angle of the main tube (1) and the branch tube (13).
9. The scanning method adopting the tube seat fillet weld ultrasonic phased array automatic scanning device as claimed in claim 1, comprising the following steps:
A plurality of magnetic wheels (14) are adsorbed on the outer wall surface of the branch pipe (13), the magnetic wheels (14) start to work, and the magnetic wheels (14) drive the base (12) to do circular motion on the branch pipe (13);
the driving structure moves circularly along with the base (12) and drives the probe detection structure (3) to move on the outer wall surface of the branch pipe (13) or the outer wall surface of the main pipe (1) to form a movement track;
the probe detection structure (3) transmits acquired data to the phased array controller (17) in real time, so that automatic detection of the ultrasonic phased array of the welding seam is realized.
