Sp. Mikhailov et Ve. Shcherbinin, MAGNETIC AND EDDY-CURRENT METHODS - PROBLEM OF AUTOMATED EVALUATION OF THE QUALITY OF BUTT WELDED-JOINTS IN MAGNETOGRAPHIC FLAW INSPECTION .1. ALGORITHM FOR SUPPRESSING THE BEAD SIGNAL, Russian journal of nondestructive testing, 29(11), 1993, pp. 843-852
The problem of the effect of the bead of a butt welded joint and relia
bility of magnetographic inspection is examined and the currently avai
lable methods of suppressing the weld signal are discussed. On the bas
is of a theoretical model of the surface dipole the authors an algorit
hm for suppressing the bead signal, the efficiency of the algorithm wa
s examined by numerical modeling.
