The invention belongs to the technical field of ultrasonic inspection in nondestructive testing, and relates to a transverse wave mode pipe external inspection electromagnetic ultrasonic spiral guided wave energy converter. The transverse wave mode pipe external inspection electromagnetic ultrasonic spiral guided wave energy converter comprises a yoke, a holding structure, walking supporting structures, pinch bar structures, permanent magnets and a coil; the energy converter is characterized in that the yoke is archy, the holding structure is connected to the upper side of the outer arc face of the yoke, the walking supporting structures are connected to planes on the two sides of the yoke, the pinch bar structures are connected to the walking supporting structures, the two archy permanent magnets are connected to the inner arc face of the yoke, the magnetisms of the inner arc faces of the two permanent magnets are opposite, and the coil is connected between the two permanent magnets; and electromagnetic ultrasonic guide waves propagating in different directions of a pipe can be generated, and therefore generation of spiral guide waves in any direction of the pipe and inspection of defects of the pipe in any direction can be achieved.
