The utility model belongs to the technical field of belong to ultrasonic testing among the nondestructive test, a compressional wave mode electromagnetic acoustic internal inspection of pipeline spiral guided wave transducer is related to, including protecting sheathing, grip the structure, the walking bearing structure, permanent magnet and coil, its characterized in that: protecting sheathing isthe arch, and protecting sheathing both sides plane is connected with walking bearing structure, and one side walking bearing structure's opposite side is connected with and grips the structure, andprotecting sheathing extrados upside is opened has the holding tank, and the holding tank in -connection has the permanent magnet, and the terminal surface all is the cambered surface about the permanent magnet, and arc surface connection has the coil on the permanent magnet, and the last lower cambered surface magnetism of permanent magnet is opposite. It can produce follows the not electromagnetic acoustic guided wave of equidirectional propagation of pipeline to realize the production of the arbitrary direction spiral guided wave of pipeline and the detection of arbitrary direction tube waydefect.
