The invention is further described with reference to the following drawings and specific examples, which are not intended to be limiting.
In a first embodiment, as shown in fig. 1, the invention provides an automatic sorting method for aluminum and aluminum alloy thin-wall pipes based on eddy current testing, which comprises the following steps:

the eddy current probe 11 is arranged at a detection area of the conveying equipment and is used for detecting quality information of the thin-walled tube in the detection area; the photoelectric switch 20 is used for determining the time when the thin-wall pipe enters and leaves the detection area;
the automatic sorting method comprises the following steps:
the flaw detector 10 transmits the quality signal obtained by the eddy current probe 11 to the programmable logic controller 30;

The qualified product is qualified, and the marking device does not act and does not mark at the moment; the blanking device acts to make the pipe enter the qualified product area. If the pipe is judged to have natural damage exceeding the specified requirement by the instrument and is an unqualified product, the marking device acts to mark the position of the natural damage; then the blanking device is actuated, and the pipe enters the unqualified material area. Thus, the automatic flaw detection of the aluminum and aluminum alloy thin-wall pipe is completed.

The removal of the quality signals at these two moments can also be implemented in the flaw detector 10.

the method for determining the defective part of the pipe comprising the defective part comprises the following steps:
and determining the defect part of the thin-wall pipe according to the transmission speed of the transmission equipment and the time when the quality signal detected by the eddy current probe 11 is the defect signal.
