Description

Technical Field

[0001] The utility model relates to the technical field of non-destructive testing of pipes, and mainly relates to a non-destructive testing device for pipes with an alarm marking function. Background Art

[0002] During the welding process of metal pipes, it is necessary to use a flaw detector to perform non-destructive testing on the welds on the metal pipes to detect defects such as cracks, sand holes, pores, white spots, inclusions, etc.

[0003] The marking function of existing non-destructive testing devices for metal pipes is not comprehensive enough. When defects are found in the pipes, the pipes cannot be marked in time or the marking is unclear. Subsequent users need to spend a lot of time to find them, which is not convenient for users to quickly find defects in metal pipes and repair them. Utility Model Content
