Description

Technical Field

[0001] The utility model relates to the technical field of metal detection equipment, in particular to an auxiliary detection device for deformation and cracks of metal materials. Background Art

[0002] During the production and processing of stainless steel pipes, cracks are prone to occur in the material. When detecting cracks on the inside of stainless steel pipes, an eddy current flaw detector is needed. When using the eddy current flaw detector, the staff is required to hold the stainless steel pipe and pass it through the probe for detection. Since the staff pushes it manually, the speed of manual pushing directly affects the detection efficiency of the stainless steel pipe. At the same time, affected by the intensity of work, the physical strength of the staff will gradually decrease, resulting in the staff being unable to maintain a fast pushing speed for a long time. In addition, affected by the length of the stainless steel pipe, the longer the length of the stainless steel pipe, the longer the time it takes for the staff, which is very inconvenient.
