FIELD: measuring equipment.
SUBSTANCE: surface of the pipe weld is probed with a beam and, according to the received signal, the limit values of the characteristics of the weld defect are determined in comparison with the standard parameters, while the pipe is placed with closed ends vertically in a metal cylindrical vessel with water, the electromagnetic wave is excited on the surface of the weld by means of a microwave generator, and, according to the time of the weld unbending by this wave, the weld control is performed.
EFFECT: improved control effectiveness.
