The invention relates to methods and devices for contactless quality control of objects made of electrically conductive materials during their manufacturing and use. A method of eddy-current testing of electrically conductive objects is based on the excitation of eddy current within an electrically conductive object by using a constant magnetic field, then scanning said electrically conductive object by using an eddy-current transducer comprising at least one constant-field inductor and at least one sensor for measuring the variation of electromagnetic field while moving the eddy-current transducer and electrically conductive object, and then registering the signals corresponding to the electromagnetic field variation, according to which the presence of faults is established. The difference is that the excitation of eddy currents within the electrically conductive object is performed by using a surface-type eddy-current transducer with the electromagnetic field variation sensors installed at the pole of the
